A useful PPC agency shortlist should make it easier to eliminate the wrong firms.
Some companies need a paid search specialist who can repair conversion tracking and manage a $15,000 monthly Google Ads budget. Others need search, social, creative, landing pages, and CRM attribution coordinated across several markets. Those are different assignments. An agency can be excellent at one and poorly suited to the other.
This guide compares eight US agencies with established paid media practices. It does not claim that one firm is universally best, and the order is not a performance ranking. Instead, each profile explains the type of engagement the agency appears built to handle, the capabilities it promotes, and the questions a buyer should ask before signing.
Disclosure: Black Propeller publishes this guide and is included in it. Our description is based on our current service pages and public case studies. Information about other agencies comes primarily from their own websites and was checked in October 2026. Agency-reported results are examples, not promises of future performance.
Key takeaways
- Black Propeller is worth considering when paid search needs to work alongside paid social, performance creative, Amazon, and reliable measurement.
- KlientBoost makes sense for companies that want paid media and landing-page experimentation handled together.
- WebFX offers the breadth and staffing of a large full-service agency.
- Disruptive Advertising combines paid search, paid social, lifecycle marketing, and conversion-rate optimization.
- SmartSites covers a broad range of paid channels and has dedicated offerings for local, multi-location, and ecommerce advertisers.
- HawkSEM positions paid search inside a wider performance program supported by its ConversionIQ measurement platform.
- Directive is the clearest specialist on this list for B2B and SaaS teams that report on pipeline rather than lead volume alone.
- AdVenture Media Group is a useful option for brands seeking a paid media specialist with consulting, measurement, and creative capabilities.

The table is a starting point, not a verdict. Service menus change, and the team assigned to your account matters more than a logo wall. Use the profiles below to narrow the field, then validate the details that affect your engagement directly.
How these agencies were selected
The original version of this article tried to turn unlike agencies into a numerical ranking. That created more certainty than the available evidence could support. Client mix, account complexity, internal talent, fee structure, and access to creative resources all affect fit. Public review totals do not resolve those differences.
For this revision, an agency had to meet four practical requirements:
- PPC is a substantial service, not a line item buried in a general marketing menu.
- The agency explains what it manages. This may include platforms, tracking, landing pages, creative, reporting, or CRM integration.
- There is public evidence of client work. Case studies may be agency-reported, but they must describe a real engagement and a measurable outcome.
- The firm serves US advertisers and has enough public information for a buyer to investigate further.
We did not award points for the largest headcount, the most reviews, or the longest client list. Those facts can indicate operating scale, but none proves that the people assigned to your account will understand its economics.
Google Partner status also should not decide the shortlist by itself. Google says Premier Partner status is reserved for the top 3% of participating companies in each country, based on factors that include client growth, retention, product diversification, and annual ad spend. It is evidence of platform activity and certification, not an independent guarantee of business results. You can read Google’s explanation of Partner requirements before treating a badge as a quality score.
Agency profiles
Black Propeller: paid media with creative and measurement in the same engagement
Black Propeller manages paid search, paid social, performance creative, Amazon advertising, SEO, HubSpot, and measurement. Its paid search service covers Google Ads, Microsoft Advertising, YouTube, Display, remarketing, and Performance Max.
The agency is headquartered in Abingdon, Maryland, and became part of Stellar in 2026. Black Propeller says its paid search team manages more than $5 million in annual ad spend. Its usual fit is a growth-stage company investing at least $10,000 a month in media, although it also has experience with substantially larger accounts.
Reporting is unusually specific on the service page: clients receive a live dashboard that refreshes every 15 minutes, with meetings generally held every two weeks and quarterly business reviews used for longer-range planning. The fee is a tiered monthly retainer rather than a percentage of ad spend. That distinction matters. A percentage fee automatically rises when media spend rises; a tiered retainer can make the management cost easier to forecast.
Public case studies show how the wider service mix can help. For World Spa, Black Propeller reports that return on ad spend increased from 1.8 to 3.7 while click-through rate rose 24.8%. For Active Skin Repair, the agency reports a 36% increase in ROAS, a 17.5% reduction in cost per acquisition, and a 12% rise in average order value. These are company-reported results from individual accounts, so use them as evidence of the work performed, not as a forecast for your account.
Best suited to: growth-stage ecommerce, home services, legal, finance, B2B, SaaS, and multi-location brands that need more than bid management.
Ask before hiring: Which specialists will work on the account each week? Which creative deliverables are included in the retainer? What data must be available before the team can optimize toward revenue rather than platform conversions?
KlientBoost: PPC and landing-page testing under one roof
KlientBoost combines Google Ads, Microsoft Advertising, paid social, conversion-rate optimization, creative, and landing-page design. Its service pages put considerable emphasis on message match: the promise in an ad should continue on the page a visitor reaches.
That makes KlientBoost a logical candidate when the account has enough traffic but the post-click experience is weak. The agency says it performs A/B testing, heatmap analysis, landing-page design, bid optimization, and revenue attribution. It also describes CRM and offline-conversion work for B2B companies with longer sales cycles.
KlientBoost publishes a large case-study library. As with any agency portfolio, the visible wins are selected examples. Ask for work from a company with a similar sales cycle, conversion volume, and average order or contract value. A successful ecommerce landing-page test tells you little about the agency’s ability to manage a six-month enterprise software buying process.
Best suited to: SaaS, B2B, and ecommerce teams that want campaign management and CRO managed as one program.
Ask before hiring: Is landing-page production included in the quoted scope? Who owns the page and test data if the engagement ends? How will the team connect ad leads to qualified opportunities or revenue?
WebFX: a large full-service team with proprietary reporting technology
WebFX offers PPC management alongside SEO, web design, content, social media, CRO, and other digital services. Its paid media offering includes Google Ads, Microsoft Advertising, paid social, programmatic advertising, and newer placements such as ads within AI products where available.
The agency’s scale is the differentiator. WebFX states that it has more than 750 digital marketing specialists and over 30 years of experience. It also promotes a proprietary revenue platform that connects marketing activity with leads and sales.
That breadth can help a marketing leader who would otherwise coordinate several vendors. It can also introduce complexity. Buyers should establish who owns strategy, how many accounts each manager carries, and which services require separate statements of work.
Best suited to: mid-market and enterprise organizations that want a broad digital program, substantial production capacity, and consolidated reporting.
Ask before hiring: Who is the senior paid media decision-maker on the account? Which platform and analytics integrations are included? Can your team export its data in a usable format if you leave?
Disruptive Advertising: multi-channel performance marketing and CRO
Disruptive Advertising provides paid search, paid social, lifecycle marketing, creative, and conversion-rate optimization. The agency works across Google, Microsoft, Meta, LinkedIn, TikTok, and other channels, with case studies spanning lead generation and ecommerce.
Its positioning is broader than search account management. The firm examines the path from audience and ad creative through landing page and customer retention. That may suit a brand whose acquisition problem crosses several stages of the funnel. A company looking only for hands-on Google Ads maintenance should confirm that the proposed team and fee do not assume a larger engagement than it needs.
Best suited to: established advertisers that want paid search and paid social coordinated with creative, CRO, or lifecycle work.
Ask before hiring: Which channel owns the testing roadmap? How does the agency distinguish an incrementally acquired customer from one who would have converted anyway? Which work is handled in-house?
SmartSites: broad PPC coverage for local, multi-location, and ecommerce brands
SmartSites manages Google Ads, Microsoft Advertising, Meta, Amazon, Local Services Ads, and other paid channels. It publishes dedicated offerings for local businesses, franchises, law firms, ecommerce companies, and enterprise advertisers.
That range is useful for companies with practical local acquisition needs. A multi-location service brand, for example, may need Search campaigns, Local Services Ads, call tracking, location-level budgets, and lead reporting in one program. SmartSites says its Client Hub brings calls, messages, and other leads into one view.
The agency also provides web design, SEO, and social media services. Buyers should identify whether the PPC team will work within the existing site or recommend a wider rebuild, and whether each channel has its own specialist.
Best suited to: local services, franchise and multi-location businesses, ecommerce retailers, and companies seeking a wider digital agency.
Ask before hiring: How are calls and booked jobs deduplicated across Google Ads and Local Services Ads? Who manages product feeds or location data? What is included in creative production?
HawkSEM: paid search tied to full-funnel attribution
HawkSEM provides paid search, paid social, SEO, remarketing, and conversion-rate optimization. Its main differentiator is ConversionIQ, a proprietary measurement system the agency says it uses to connect campaign activity with qualified leads and revenue.
The public paid-search material covers Google and Microsoft campaigns as well as Shopping, video, and display. HawkSEM also publishes vertical-specific services for ecommerce, home services, legal, healthcare, education, and B2B companies.
The agency reports that work for Peer Software increased conversions by 128% while reducing cost per conversion by more than 46%. As with every case study in this guide, the result belongs to one engagement and should not be treated as a typical return.
Best suited to: companies that need paid media evaluated against downstream lead quality or revenue and want a broader performance marketing partner.
Ask before hiring: What systems must connect to ConversionIQ? Can your company retain the underlying data and reporting history? How does the team handle offline conversions and delayed revenue?
Directive: paid media for B2B and SaaS pipeline
Directive is the most narrowly positioned agency on this list. Its PPC service is built for B2B companies and centers on Google Ads and Microsoft Advertising, qualified opportunities, cost per opportunity, and customer acquisition economics.
That language is important. B2B accounts often look healthy inside an ad platform while sending the sales team poor-fit leads. Directive says it handles campaign architecture, keyword strategy, landing-page optimization, conversion tracking, and measurement against pipeline. It also offers paid social, performance creative, CRO, and revenue operations services.
The specialization may be valuable for software and technology companies with long sales cycles and multiple buying stakeholders. It is less obviously suited to a local service company or a small ecommerce store.
Best suited to: B2B SaaS and technology companies that can connect advertising data to CRM opportunities and customer revenue.
Ask before hiring: Which lifecycle stages will be sent back to the ad platforms? How will the agency account for pipeline created outside paid search? What conversion volume is required for value-based bidding?
AdVenture Media Group: specialist paid media with consulting depth
AdVenture Media Group works across paid search, paid social, programmatic advertising, creative, measurement, and marketing automation. Its site shows offices in New York, Philadelphia, and South Florida and features work across ecommerce, lead generation, and enterprise accounts.
AdVenture also provides consulting and training. That can be useful when an internal team wants outside diagnosis or a new operating system without outsourcing every campaign indefinitely. Its public case studies describe work on lead quality, cost per click, conversion rate, and customer acquisition.
Because the firm now positions itself as AI-first, buyers should ask what that means in daily account management. Every major ad platform already uses machine learning. The useful distinction is whether the agency has better measurement, creative inputs, exclusions, and human review, not whether it uses AI at all.
Best suited to: ecommerce, lead-generation, and enterprise advertisers looking for a specialist agency or strategic consulting support.
Ask before hiring: Which decisions are automated and which require strategist approval? How are incrementality and lead quality measured? Can the agency work alongside an internal media team?
What a capable PPC agency should deliver
An impressive pitch is easy to produce. The operating details reveal whether an agency can manage the account.
A measurement plan before a scaling plan
The agency should identify the conversion actions that matter, test whether they fire correctly, and agree on the source of truth. For ecommerce, that may mean reconciling platform revenue with the store and analytics platform. For lead generation, it may mean sending qualified-lead, opportunity, or sale data back from the CRM.
Google recommends connecting first-party data sources so its bidding systems can optimize with stronger signals. That does not mean uploading every available event. The agency should explain which events will be primary conversions, which are observations, and how duplicate or low-quality actions will be excluded. Google’s current data-strength guidance is a useful reference, but the implementation must reflect your business.
Before changing bids or budgets, a new partner should complete a Google Ads conversion-tracking audit. Scaling from broken measurement only produces faster, less intelligible waste.
Account access that belongs to the advertiser
Your company should retain administrative access to its ad accounts, analytics properties, tag manager, product feeds, landing pages, and creative files. The agency can work through a manager account without becoming the sole owner.
Put the exit process in the agreement. Confirm that campaigns, audiences, scripts, dashboards, and historical data remain accessible after termination. An agency’s proprietary platform may be licensed only during the engagement, but your underlying business data should not disappear with it.
A written testing backlog
“Continuous optimization” is too vague to buy. A useful plan names the tests, the order, the success metric, and the decision rule. Early work may include search-term exclusions, geographic settings, conversion cleanup, campaign structure, feed quality, ad messaging, creative formats, or landing-page friction.
The agency also needs enough volume to learn. Splitting a modest budget across too many campaigns and audiences can leave every test inconclusive. Ask how the team will concentrate data before expanding.
Reporting that reaches business outcomes
Clicks, impressions, and platform conversions help diagnose a campaign. They are not the final score.
An ecommerce report should connect spend with contribution margin, new-customer revenue, returns, and repeat purchasing where the data allows. A lead-generation report should distinguish raw inquiries from qualified leads, appointments, opportunities, and sales. A B2B report should account for lag between the click and the closed deal.
If an agency cannot access downstream data, it should say so and define the interim metrics it will use. False precision is worse than an honest measurement limit.
A clear communication rhythm
Know who attends calls, who works in the account, and how urgent issues are handled. Monthly reporting can be adequate for a stable account. A major launch, tracking failure, or volatile seasonal period needs faster communication.
The best cadence is the one that supports decisions. A weekly call that recites dashboard numbers is less useful than a concise biweekly review with decisions, owners, and deadlines.
How to choose the right PPC agency for your business
Begin with the constraint
Write down the main reason performance is stuck. If you do not know, make diagnosis the first paid assignment.
- Poor tracking: prioritize analytics, tag management, CRM integration, and offline conversions.
- Enough traffic but weak conversion: look for landing-page and CRO capability.
- Creative fatigue: verify production capacity and testing speed, especially for paid social.
- Low-quality leads: focus on CRM feedback, qualification logic, keyword intent, and value-based optimization.
- Complex product catalog: look for Shopping, feed management, merchandising, and margin-aware bidding.
- Many service areas: test the agency’s experience with location structure, call tracking, local landing pages, and Local Services Ads.
- Long B2B sales cycle: require opportunity and revenue reporting, not form-fill optimization alone.
This exercise usually removes several agencies before the first call.
Compare the proposed team, not the sales team
Ask to meet the person who will own strategy and learn who will perform routine optimization. Request the expected client load for each role. A famous agency with an overstretched account team can be a worse choice than a smaller firm whose senior specialists remain involved.
Relevant experience matters, but define “relevant” carefully. The closest match may share your sales cycle, economics, geography, or operational constraint rather than your industry label.
Give finalists the same brief
Provide the same business goals, account context, media spend, target markets, margins or lead values, and known tracking problems. Then compare how each firm reasons.
A credible proposal should state assumptions and limits. Be cautious when an agency promises a specific ROAS before seeing reliable conversion data, or proposes a large budget increase without explaining the marginal return it expects.
For a regional shortlist, our separate guide to PPC agencies in Maryland compares firms with local operations. Use that page when proximity or Maryland market knowledge is a genuine requirement. This national guide should remain focused on operating fit.
Best PPC agency pricing: what to compare
There is no dependable national price range that covers all the agencies and account types in this guide. A single-market Search account and a multi-country program with paid social, landing pages, feeds, and CRM attribution do not belong in the same average.
Most proposals use one or a combination of these models:
- Flat monthly retainer: predictable, but the scope and service limits must be explicit.
- Percentage of ad spend: simple to calculate, although the agency earns more when spend rises even if workload does not rise proportionally.
- Tiered retainer: the fee changes when spend or complexity crosses agreed thresholds.
- Hourly or project fee: common for audits, tracking implementations, account builds, and consulting.
- Performance component: may align incentives, but only when revenue, attribution, margins, refunds, and the agency’s degree of control are defined carefully.
Ask every finalist for a total first-year cost, not only the management fee. Include onboarding, tracking work, landing pages, creative production, feed management, software, travel, and contract termination terms.
Then compare capacity. How many strategist hours, creative concepts, landing pages, meetings, and markets are included? A lower retainer can cost more if the internal team must supply all the work omitted from the proposal.
Twelve questions to ask on the first call
- Who will make strategic decisions on our account, and can we meet that person before signing?
- How many accounts does each assigned team member manage?
- What would you inspect during the first two weeks?
- Which business metric will guide optimization?
- How will you verify and improve conversion tracking?
- How will CRM, sales, margin, or repeat-purchase data affect bidding?
- What creative and landing-page work is included?
- Which tasks are automated, and how are automated changes reviewed?
- How often will we receive decisions and recommendations, not just reports?
- What must our internal team provide for the engagement to succeed?
- Who owns the accounts, campaigns, data, and creative when the contract ends?
- Can you show an engagement with similar economics and explain what did not work as well as what did?
The final question is especially revealing. A team that can discuss a failed test, weak assumption, or measurement problem usually understands the work more deeply than one that presents only uninterrupted wins.
Warning signs during the sales process
- The agency guarantees a ranking, revenue figure, lead volume, or ROAS before auditing the account.
- The pitch focuses on proprietary AI but cannot explain the data, controls, or human decisions behind it.
- Case studies omit the time period, starting point, spend change, or business context.
- The agency wants to create and own the ad account.
- Reports stop at impressions, clicks, and platform conversions even though sales data is available.
- The proposal spreads a limited budget across many channels without explaining how each will gather enough data.
- The contract makes it difficult to retain campaigns, tracking, creative, or reporting history.
- The sales team cannot identify the people who will actually manage the work.
Frequently asked questions
What does a PPC agency do?
A PPC agency plans, builds, manages, and measures paid advertising. Depending on the engagement, that can include keyword and audience research, campaign structure, bidding, ad copy, creative, product feeds, landing pages, conversion tracking, experimentation, and reporting. Some agencies specialize in paid search; others manage a larger performance program.
If you are new to the channel, our guide to what PPC is and how it works explains the basic auction and campaign types.
How much does a PPC agency cost?
The cost depends on media spend, number of platforms, markets, conversion-tracking condition, creative requirements, landing-page work, and reporting complexity. Compare the complete scope and first-year cost. A quote that excludes measurement or creative may look cheaper while requiring far more internal support.
How long does a new PPC agency need to improve performance?
There is no universal 30-, 60-, or 90-day answer. A mature account with sound tracking and enough conversions can support useful decisions quickly. A new or damaged account may first need measurement repairs, a rebuild, and enough conversion volume to evaluate the changes. Ask for a phased plan with early diagnostic milestones rather than a guaranteed result date.
Is Google Premier Partner status important?
It is useful evidence that an agency meets Google’s current program requirements and operates at meaningful scale. It does not prove that the assigned team understands your business, and it should not outweigh relevant case work, measurement quality, account ownership, or the proposed team.
Should I hire a PPC specialist or a full-service agency?
Hire a specialist when the main constraint sits inside paid media and your team can supply strategy, creative, web development, and analytics support. Consider a broader agency when performance depends on several of those functions moving together. In either case, make one person accountable for the overall acquisition result.
Should I hire an agency or build an in-house team?
An in-house hire offers close business context and daily access. An agency provides a wider set of specialists and exposure to more accounts. The decision depends on workload and complexity. Some companies use an internal growth lead for ownership and an agency for platform execution, creative, or measurement. Define decision rights before adopting a hybrid model.
Which PPC agency is best for a small business?
The best fit is usually an agency whose minimum viable engagement matches the business’s media budget and conversion volume. A large team built for enterprise complexity may be unnecessary. Small businesses should prioritize clean tracking, local or niche experience, clear ownership, and a scope that leaves enough budget for the media itself.
Start with the account, not the agency list
The shortlist should be the beginning of the decision, not the decision itself. Give two or three suitable firms the same information and ask each to explain the first problems it would investigate. The strongest answer will be specific to your account, candid about missing data, and clear about the tradeoffs.

Ask before hiring: Which specialists will work on the account each week? Which creative deliverables are included in the retainer? What data must be available before the team can optimize toward revenue rather than platform conversions?
KlientBoost: PPC and landing-page testing under one roof
KlientBoost combines Google Ads, Microsoft Advertising, paid social, conversion-rate optimization, creative, and landing-page design. Its service pages put considerable emphasis on message match: the promise in an ad should continue on the page a visitor reaches.
That makes KlientBoost a logical candidate when the account has enough traffic but the post-click experience is weak. The agency says it performs A/B testing, heatmap analysis, landing-page design, bid optimization, and revenue attribution. It also describes CRM and offline-conversion work for B2B companies with longer sales cycles.
KlientBoost publishes a large case-study library. As with any agency portfolio, the visible wins are selected examples. Ask for work from a company with a similar sales cycle, conversion volume, and average order or contract value. A successful ecommerce landing-page test tells you little about the agency’s ability to manage a six-month enterprise software buying process.

WebFX offers PPC management alongside SEO, web design, content, social media, CRO, and other digital services. Its paid media offering includes Google Ads, Microsoft Advertising, paid social, programmatic advertising, and newer placements such as ads within AI products where available.
The agency’s scale is the differentiator. WebFX states that it has more than 750 digital marketing specialists and over 30 years of experience. It also promotes a proprietary revenue platform that connects marketing activity with leads and sales.

Disruptive Advertising: multi-channel performance marketing and CRO
Disruptive Advertising provides paid search, paid social, lifecycle marketing, creative, and conversion-rate optimization. The agency works across Google, Microsoft, Meta, LinkedIn, TikTok, and other channels, with case studies spanning lead generation and ecommerce.
Its positioning is broader than search account management. The firm examines the path from audience and ad creative through landing page and customer retention. That may suit a brand whose acquisition problem crosses several stages of the funnel. A company looking only for hands-on Google Ads maintenance should confirm that the proposed team and fee do not assume a larger engagement than it needs.

Ask before hiring: Which channel owns the testing roadmap? How does the agency distinguish an incrementally acquired customer from one who would have converted anyway? Which work is handled in-house?
SmartSites: broad PPC coverage for local, multi-location, and ecommerce brands
SmartSites manages Google Ads, Microsoft Advertising, Meta, Amazon, Local Services Ads, and other paid channels. It publishes dedicated offerings for local businesses, franchises, law firms, ecommerce companies, and enterprise advertisers.
That range is useful for companies with practical local acquisition needs. A multi-location service brand, for example, may need Search campaigns, Local Services Ads, call tracking, location-level budgets, and lead reporting in one program. SmartSites says its Client Hub brings calls, messages, and other leads into one view.
The agency also provides web design, SEO, and social media services. Buyers should identify whether the PPC team will work within the existing site or recommend a wider rebuild, and whether each channel has its own specialist.
Best suited to: local services, franchise and multi-location businesses, ecommerce retailers, and companies seeking a wider digital agency.
Ask before hiring: How are calls and booked jobs deduplicated across Google Ads and Local Services Ads? Who manages product feeds or location data? What is included in creative production?
HawkSEM: paid search tied to full-funnel attribution
HawkSEM provides paid search, paid social, SEO, remarketing, and conversion-rate optimization. Its main differentiator is ConversionIQ, a proprietary measurement system the agency says it uses to connect campaign activity with qualified leads and revenue.
The public paid-search material covers Google and Microsoft campaigns as well as Shopping, video, and display. HawkSEM also publishes vertical-specific services for ecommerce, home services, legal, healthcare, education, and B2B companies.
The agency reports that work for Peer Software increased conversions by 128% while reducing cost per conversion by more than 46%. As with every case study in this guide, the result belongs to one engagement and should not be treated as a typical return.
Best suited to: companies that need paid media evaluated against downstream lead quality or revenue and want a broader performance marketing partner.
Ask before hiring: What systems must connect to ConversionIQ? Can your company retain the underlying data and reporting history? How does the team handle offline conversions and delayed revenue?
Directive: paid media for B2B and SaaS pipeline
Directive is the most narrowly positioned agency on this list. Its PPC service is built for B2B companies and centers on Google Ads and Microsoft Advertising, qualified opportunities, cost per opportunity, and customer acquisition economics.
That language is important. B2B accounts often look healthy inside an ad platform while sending the sales team poor-fit leads. Directive says it handles campaign architecture, keyword strategy, landing-page optimization, conversion tracking, and measurement against pipeline. It also offers paid social, performance creative, CRO, and revenue operations services.
The specialization may be valuable for software and technology companies with long sales cycles and multiple buying stakeholders. It is less obviously suited to a local service company or a small ecommerce store.
Best suited to: B2B SaaS and technology companies that can connect advertising data to CRM opportunities and customer revenue.
Ask before hiring: Which lifecycle stages will be sent back to the ad platforms? How will the agency account for pipeline created outside paid search? What conversion volume is required for value-based bidding?
AdVenture Media Group: specialist paid media with consulting depth
AdVenture Media Group works across paid search, paid social, programmatic advertising, creative, measurement, and marketing automation. Its site shows offices in New York, Philadelphia, and South Florida and features work across ecommerce, lead generation, and enterprise accounts.
AdVenture also provides consulting and training. That can be useful when an internal team wants outside diagnosis or a new operating system without outsourcing every campaign indefinitely. Its public case studies describe work on lead quality, cost per click, conversion rate, and customer acquisition.
Because the firm now positions itself as AI-first, buyers should ask what that means in daily account management. Every major ad platform already uses machine learning. The useful distinction is whether the agency has better measurement, creative inputs, exclusions, and human review, not whether it uses AI at all.
Best suited to: ecommerce, lead-generation, and enterprise advertisers looking for a specialist agency or strategic consulting support.
Ask before hiring: Which decisions are automated and which require strategist approval? How are incrementality and lead quality measured? Can the agency work alongside an internal media team?
What a capable PPC agency should deliver
An impressive pitch is easy to produce. The operating details reveal whether an agency can manage the account.
A measurement plan before a scaling plan
The agency should identify the conversion actions that matter, test whether they fire correctly, and agree on the source of truth. For ecommerce, that may mean reconciling platform revenue with the store and analytics platform. For lead generation, it may mean sending qualified-lead, opportunity, or sale data back from the CRM.
Google recommends connecting first-party data sources so its bidding systems can optimize with stronger signals. That does not mean uploading every available event. The agency should explain which events will be primary conversions, which are observations, and how duplicate or low-quality actions will be excluded. Google’s current data-strength guidance is a useful reference, but the implementation must reflect your business.
Before changing bids or budgets, a new partner should complete a Google Ads conversion-tracking audit. Scaling from broken measurement only produces faster, less intelligible waste.
Account access that belongs to the advertiser
Your company should retain administrative access to its ad accounts, analytics properties, tag manager, product feeds, landing pages, and creative files. The agency can work through a manager account without becoming the sole owner.
Put the exit process in the agreement. Confirm that campaigns, audiences, scripts, dashboards, and historical data remain accessible after termination. An agency’s proprietary platform may be licensed only during the engagement, but your underlying business data should not disappear with it.
A written testing backlog
“Continuous optimization” is too vague to buy. A useful plan names the tests, the order, the success metric, and the decision rule. Early work may include search-term exclusions, geographic settings, conversion cleanup, campaign structure, feed quality, ad messaging, creative formats, or landing-page friction.
The agency also needs enough volume to learn. Splitting a modest budget across too many campaigns and audiences can leave every test inconclusive. Ask how the team will concentrate data before expanding.
Reporting that reaches business outcomes
Clicks, impressions, and platform conversions help diagnose a campaign. They are not the final score.
An ecommerce report should connect spend with contribution margin, new-customer revenue, returns, and repeat purchasing where the data allows. A lead-generation report should distinguish raw inquiries from qualified leads, appointments, opportunities, and sales. A B2B report should account for lag between the click and the closed deal.
If an agency cannot access downstream data, it should say so and define the interim metrics it will use. False precision is worse than an honest measurement limit.
A clear communication rhythm
Know who attends calls, who works in the account, and how urgent issues are handled. Monthly reporting can be adequate for a stable account. A major launch, tracking failure, or volatile seasonal period needs faster communication.
The best cadence is the one that supports decisions. A weekly call that recites dashboard numbers is less useful than a concise biweekly review with decisions, owners, and deadlines.
How to choose the right PPC agency for your business
Begin with the constraint
Write down the main reason performance is stuck. If you do not know, make diagnosis the first paid assignment.
- Poor tracking: prioritize analytics, tag management, CRM integration, and offline conversions.
- Enough traffic but weak conversion: look for landing-page and CRO capability.
- Creative fatigue: verify production capacity and testing speed, especially for paid social.
- Low-quality leads: focus on CRM feedback, qualification logic, keyword intent, and value-based optimization.
- Complex product catalog: look for Shopping, feed management, merchandising, and margin-aware bidding.
- Many service areas: test the agency’s experience with location structure, call tracking, local landing pages, and Local Services Ads.
- Long B2B sales cycle: require opportunity and revenue reporting, not form-fill optimization alone.
This exercise usually removes several agencies before the first call.
Compare the proposed team, not the sales team
Ask to meet the person who will own strategy and learn who will perform routine optimization. Request the expected client load for each role. A famous agency with an overstretched account team can be a worse choice than a smaller firm whose senior specialists remain involved.
Relevant experience matters, but define “relevant” carefully. The closest match may share your sales cycle, economics, geography, or operational constraint rather than your industry label.
Give finalists the same brief
Provide the same business goals, account context, media spend, target markets, margins or lead values, and known tracking problems. Then compare how each firm reasons.
A credible proposal should state assumptions and limits. Be cautious when an agency promises a specific ROAS before seeing reliable conversion data, or proposes a large budget increase without explaining the marginal return it expects.

Best PPC agency pricing: what to compare
There is no dependable national price range that covers all the agencies and account types in this guide. A single-market Search account and a multi-country program with paid social, landing pages, feeds, and CRM attribution do not belong in the same average.
Most proposals use one or a combination of these models:
- Flat monthly retainer: predictable, but the scope and service limits must be explicit.
- Percentage of ad spend: simple to calculate, although the agency earns more when spend rises even if workload does not rise proportionally.
- Tiered retainer: the fee changes when spend or complexity crosses agreed thresholds.
- Hourly or project fee: common for audits, tracking implementations, account builds, and consulting.
- Performance component: may align incentives, but only when revenue, attribution, margins, refunds, and the agency’s degree of control are defined carefully.
Ask every finalist for a total first-year cost, not only the management fee. Include onboarding, tracking work, landing pages, creative production, feed management, software, travel, and contract termination terms.
Then compare capacity. How many strategist hours, creative concepts, landing pages, meetings, and markets are included? A lower retainer can cost more if the internal team must supply all the work omitted from the proposal.
Twelve questions to ask on the first call
- Who will make strategic decisions on our account, and can we meet that person before signing?
- How many accounts does each assigned team member manage?
- What would you inspect during the first two weeks?
- Which business metric will guide optimization?
- How will you verify and improve conversion tracking?
- How will CRM, sales, margin, or repeat-purchase data affect bidding?
- What creative and landing-page work is included?
- Which tasks are automated, and how are automated changes reviewed?
- How often will we receive decisions and recommendations, not just reports?
- What must our internal team provide for the engagement to succeed?
- Who owns the accounts, campaigns, data, and creative when the contract ends?
- Can you show an engagement with similar economics and explain what did not work as well as what did?
The final question is especially revealing. A team that can discuss a failed test, weak assumption, or measurement problem usually understands the work more deeply than one that presents only uninterrupted wins.
Warning signs during the sales process
- The agency guarantees a ranking, revenue figure, lead volume, or ROAS before auditing the account.
- The pitch focuses on proprietary AI but cannot explain the data, controls, or human decisions behind it.
- Case studies omit the time period, starting point, spend change, or business context.
- The agency wants to create and own the ad account.
- Reports stop at impressions, clicks, and platform conversions even though sales data is available.
- The proposal spreads a limited budget across many channels without explaining how each will gather enough data.
- The contract makes it difficult to retain campaigns, tracking, creative, or reporting history.
- The sales team cannot identify the people who will actually manage the work.
Frequently asked questions
What does a PPC agency do?
A PPC agency plans, builds, manages, and measures paid advertising. Depending on the engagement, that can include keyword and audience research, campaign structure, bidding, ad copy, creative, product feeds, landing pages, conversion tracking, experimentation, and reporting. Some agencies specialize in paid search; others manage a larger performance program.
If you are new to the channel, our guide to what PPC is and how it works explains the basic auction and campaign types.
How much does a PPC agency cost?
The cost depends on media spend, number of platforms, markets, conversion-tracking condition, creative requirements, landing-page work, and reporting complexity. Compare the complete scope and first-year cost. A quote that excludes measurement or creative may look cheaper while requiring far more internal support.
How long does a new PPC agency need to improve performance?
There is no universal 30-, 60-, or 90-day answer. A mature account with sound tracking and enough conversions can support useful decisions quickly. A new or damaged account may first need measurement repairs, a rebuild, and enough conversion volume to evaluate the changes. Ask for a phased plan with early diagnostic milestones rather than a guaranteed result date.
Is Google Premier Partner status important?
It is useful evidence that an agency meets Google’s current program requirements and operates at meaningful scale. It does not prove that the assigned team understands your business, and it should not outweigh relevant case work, measurement quality, account ownership, or the proposed team.
Should I hire a PPC specialist or a full-service agency?
Hire a specialist when the main constraint sits inside paid media and your team can supply strategy, creative, web development, and analytics support. Consider a broader agency when performance depends on several of those functions moving together. In either case, make one person accountable for the overall acquisition result.
Should I hire an agency or build an in-house team?
An in-house hire offers close business context and daily access. An agency provides a wider set of specialists and exposure to more accounts. The decision depends on workload and complexity. Some companies use an internal growth lead for ownership and an agency for platform execution, creative, or measurement. Define decision rights before adopting a hybrid model.
Which PPC agency is best for a small business?
The best fit is usually an agency whose minimum viable engagement matches the business’s media budget and conversion volume. A large team built for enterprise complexity may be unnecessary. Small businesses should prioritize clean tracking, local or niche experience, clear ownership, and a scope that leaves enough budget for the media itself.
Start with the account, not the agency list
The shortlist should be the beginning of the decision, not the decision itself. Give two or three suitable firms the same information and ask each to explain the first problems it would investigate. The strongest answer will be specific to your account, candid about missing data, and clear about the tradeoffs.
Black Propeller offers paid media audits for companies that want an evidence-based view of their current search and social programs. We review measurement, account structure, search terms, targeting, creative, landing pages, and the connection between platform conversions and business results.

PakarPBN
A Private Blog Network (PBN) is a collection of websites that are controlled by a single individual or organization and used primarily to build backlinks to a “money site” in order to influence its ranking in search engines such as Google. The core idea behind a PBN is based on the importance of backlinks in Google’s ranking algorithm. Since Google views backlinks as signals of authority and trust, some website owners attempt to artificially create these signals through a controlled network of sites.
In a typical PBN setup, the owner acquires expired or aged domains that already have existing authority, backlinks, and history. These domains are rebuilt with new content and hosted separately, often using different IP addresses, hosting providers, themes, and ownership details to make them appear unrelated. Within the content published on these sites, links are strategically placed that point to the main website the owner wants to rank higher. By doing this, the owner attempts to pass link equity (also known as “link juice”) from the PBN sites to the target website.
The purpose of a PBN is to give the impression that the target website is naturally earning links from multiple independent sources. If done effectively, this can temporarily improve keyword rankings, increase organic visibility, and drive more traffic from search results.
However, using a PBN violates Google’s Webmaster Guidelines because it is considered a manipulative link scheme. Google actively works to detect and penalize such networks through algorithm updates and manual actions. If discovered, the target website may lose rankings or be removed from search results entirely. For this reason, while PBNs may offer short-term ranking gains, they carry significant long-term risks.
