A GEO agency can sound convincing long before it has proved that it can change what an AI answer says.
The vocabulary is easy to borrow: prompt tracking, citation share, entity optimization, answer visibility. The harder questions come later. Which prompts will the agency monitor? How will it separate a fleeting mention from a repeatable gain? Who will fix the site, create the evidence, earn third-party coverage and connect AI referrals with pipeline?
That is where the firms on this list differ.
We reviewed the public GEO or AEO service material, measurement claims, case studies, commercial information and client fit of US GEO agencies active in AI search. The ranking favors firms that can execute the work, not merely report visibility from a software dashboard.
Disclosure: Black Propeller publishes this article and is included in the ranking. That conflict is unavoidable, so the evidence standard is stated below and gaps are left visible. “Not publicly disclosed” means exactly that; it is not replaced with an estimate.
The shortlist
| Rank | Agency | Strongest fit | What is publicly clear | Pricing visibility |
|---|---|---|---|---|
| 1 | Black Propeller | Mid-market brands that want GEO connected with paid media, SEO and conversion data | Dedicated GEO and AEO services; first-party results from its own site | Custom; no public starting price |
| 2 | iPullRank | Enterprise teams with complex sites and technical AI-search needs | Detailed measurement framework, Relevance Engineering and extensive public research | Not publicly disclosed |
| 3 | Siege Media | Brands using content, digital PR and editorial placements to build citation authority | GEO service, citation-graph approach and monthly share-of-voice reporting | Not publicly disclosed |
| 4 | Directive | B2B companies that want AI visibility tied to demand generation | Dedicated B2B GEO methodology covering entities, content, structured data and reporting | Not publicly disclosed |
| 5 | Go Fish Digital | Ecommerce and large sites needing page- and passage-level technical work | Semantic audits, passage optimization, technical SEO and digital PR | Custom proposals |
| 6 | Victorious | Mid-market and enterprise teams that prefer structured 90-day work cycles | Integrated SEO and GEO service with monthly reporting | Scoped after an audit |
| 7 | NoGood | Growth-stage and larger brands wanting AEO inside a broader growth program | Full-service AEO spanning technical work, content, earned media and monitoring | Not published on its AEO page |
| 8 | Omniscient Digital | B2B software companies that need content-led SEO and AEO | Verified directory reviews describe SEO, content, link building and AEO delivery | Directory minimum of $5,000; GEO scope not separately priced |
| 9 | First Page Sage | B2B organizations that favor thought leadership and editorial content | SEO and GEO positioned together around lead generation | Not publicly disclosed |
| 10 | Single Grain | Brands wanting GEO combined with content, PR, local presence and conversion work | Broad GEO service with prompt research, technical work, distribution and attribution | Not publicly disclosed |
There is no universal “best” GEO agency. A retailer with thousands of product pages should not buy the same program as a B2B software company with a long sales cycle. The ranking is a starting point for a shortlist, not a substitute for reviewing the proposed team, scope and evidence.
What we mean by a GEO agency
Generative engine optimization is the work of improving whether, where and how a brand or source appears in AI-generated answers. Depending on the surface and question, the desired outcome may be a citation, an accurate brand mention, inclusion in a shortlist or an AI-referred visit that becomes pipeline.
The term came into wider use after researchers introduced a GEO framework and benchmark for generative-engine visibility. Their peer-reviewed KDD 2024 paper reported visibility gains of up to 40% in its experimental setting and, importantly, found that the effectiveness of individual tactics varied by domain. That result is evidence that optimization is possible under the study conditions, not a promise that adding statistics will lift every commercial page by 40%. Read the published GEO paper through the ACM.
In agency practice, GEO, AEO, AI search optimization and LLM optimization overlap heavily. Firms draw the boundaries differently. Buyers should pay more attention to the proposed work than the acronym on the proposal.
A credible engagement usually touches four areas:
- Baseline measurement: a stable set of prompts, engines, locations and testing conditions
- Owned assets: pages, product information, case studies, original research and technical access
- Off-site evidence: press, reviews, communities, directories and other sources an answer engine may retrieve
- Business reporting: AI visibility alongside referral traffic, conversions, pipeline and assisted outcomes
A tracking dashboard may be part of that work. It is not the work by itself.

How the agencies were ranked
This is an editorial comparison based on public information available on October 28, 2026. Each firm was reviewed against the same questions.
Can a buyer see an actual service?
The agency needed a dedicated GEO, AEO or AI-search offering, or clear evidence that it delivers the work inside a broader organic program. A passing reference to “AI-ready content” was not enough.
Does the scope go beyond on-page rewriting?
The stronger offerings address some combination of technical access, content, entity clarity, digital PR, third-party mentions, communities and measurement. No single tactic controls an AI answer.
Is the measurement method intelligible?
We looked for prompt-level tracking across more than one engine, citation or mention analysis, AI referral traffic and some connection to conversions or pipeline. Proprietary software was not awarded points merely for being proprietary.
Is there public evidence?
Named case studies, verified client reviews, published methods and first-party experiments are all useful, but they are not equivalent. Agency-authored claims are described as such. Directory reviews are identified as directory evidence. No claim was upgraded into an independent result without an independent source.
Can a buyer understand the fit?
Industry, company size, operating model and likely engagement shape matter. An agency is more useful when it says whom it serves and what its team actually does.
Price received less weight because most firms do not publish a GEO rate. A directory minimum is not the same as the likely price of a full GEO engagement, so the comparison does not pretend otherwise.
The top 10 GEO agencies in the US
1. Black Propeller
Best fit: Mid-market companies that want AI-search work connected with paid search, paid social, SEO and conversion measurement.
Black Propeller has separate GEO and AEO services. Its public scope covers AI and LLM content structuring, semantic optimization, conversational readiness, direct-answer content, structured data and authority signals.
The case for placing it first is integration. The same agency can use paid-search query data to identify commercially useful language, SEO data to understand existing demand, and conversion records to distinguish a prompt that attracts attention from one that contributes to revenue. That does not make paid media a GEO tactic. It gives the GEO team better evidence for prioritization.
Black Propeller has also published results from its own site through a Pixis customer story. The reported program reorganized the blog into topic clusters, mapped content against tracked prompts and combined content work with technical changes. Because Pixis and Black Propeller are part of the same wider group, buyers should treat this as first-party evidence, not an independent case study.
What to verify in the sales process: the exact engines and prompts included, how off-site authority work is handled, which team owns implementation, and the reporting connection between citations, visits and qualified outcomes.
Pricing: custom. No public GEO starting price was found.
2. iPullRank
Best fit: Enterprise organizations that need a technical operating model for AI search.
iPullRank has one of the most developed public bodies of work in this category. Its AI Search Manual explains its Relevance Engineering approach, while its published guide to AI-search measurement separates input measures such as passage relevance and bot activity from channel measures such as citation rate, share of voice, referral traffic and conversions.
That depth matters for large sites. GEO on an enterprise domain may involve renderability, crawl behavior, query fan-out, passage retrieval, entity disambiguation, analytics and coordination among SEO, content, PR and engineering teams. iPullRank speaks directly to that complexity instead of reducing the work to content formatting.
The tradeoff is also clear. This is likely to suit a buyer with internal specialists and implementation capacity better than a small company looking for a simple managed content package.
What to verify: the implementation split between the agency and internal teams, the reporting cadence, how synthetic prompts are selected, and which changes the agency can ship without client engineering support.
Pricing: not publicly disclosed in the sources reviewed.
3. Siege Media
Best fit: Companies using content, digital PR and third-party editorial coverage as their main organic growth levers.
Siege Media’s GEO service is built around what it calls the citation graph: owned content, editorial roundups, digital PR, communities and other sources that influence AI answers. That is a useful distinction. A brand cannot make itself independently authoritative simply by saying the same thing more clearly on its own site.
The agency says its engagements report LLM share of voice, citations earned on affected surfaces, AI referral behavior and classic organic measures. Its long content-marketing background should appeal to brands that need both the source asset and the distribution around it.
Buyers should still ask how community work is disclosed and governed. A legitimate program should not depend on undisclosed promotion, manufactured consensus or low-quality placements that create a reputation problem later.
What to verify: the mix of owned content, PR, editorial placements and community work; whether placement costs are included; and how revenue influence is calculated.
Pricing: not publicly disclosed.
4. Directive
Best fit: B2B companies that want GEO framed around buyers, demand and pipeline.
Directive’s B2B GEO service covers entity and topic mapping, content optimization, structured data, technical work and visibility reporting. The public methodology is explicitly aimed at B2B discovery across ChatGPT, Claude, Perplexity, Gemini, Copilot and Google’s AI surfaces.
Its positioning will be familiar to B2B marketing teams: organize work around personas, long-tail buying questions and pipeline influence rather than treating every mention as equally valuable. That is sensible, although the public page provides more methodology than independently verifiable case-study detail.
There is one item buyers should question carefully. Directive’s page refers to submitting content to AI datasets and platforms. The agency should explain exactly what that means for each engine, because there is no universal submission mechanism that places a commercial page into model answers.
What to verify: what “indexing and visibility” work consists of, how prompt performance is connected with pipeline, and whether digital PR or off-site citation work is included.
Pricing: not publicly disclosed.
5. Go Fish Digital
Best fit: Ecommerce, marketplaces and large content libraries needing technical and passage-level analysis.
Go Fish Digital’s GEO service combines semantic content audits, page- and passage-level optimization, technical SEO and digital PR. The passage-level emphasis is useful because generative systems may retrieve a relevant section rather than reward an entire page as a single unit.
The agency also connects traditional discoverability with AI visibility. That avoids a common false choice. Content still needs to be accessible and understood before an engine can retrieve it, even though conventional ranking and AI citation are not identical outcomes.
Some claims on the public service page describe relationships between citations, rankings and AI inclusion quite strongly. Ask the team which conclusions come from client data, published research or internal modeling.
What to verify: the tools and datasets used for passage scoring, how product or category pages are prioritized, the role of digital PR, and the business outcomes included in reporting.
Pricing: custom proposals; no GEO starting figure was found on the service page.
6. Victorious
Best fit: Mid-market and enterprise teams that want GEO incorporated into an established SEO program.
Victorious presents GEO as an extension of SEO rather than a separate replacement. Its GEO service page covers entity clarity, extractable content, third-party authority and visibility across multiple AI platforms.
The operating rhythm is unusually clear. Victorious says its programs run in 90-day sprints with monthly reporting and that the first full assessment comes at the end of the initial sprint. That is not a guarantee of results in 90 days; it is a defined review cycle, which is more useful.
The agency prices after an audit according to site size, category competition and the condition of the existing foundation. Buyers who want a published package will not find one, but the scoping logic is visible.
What to verify: the deliverables inside the first sprint, whether implementation is included, how third-party authority is built, and which metrics determine the next sprint.
Pricing: scoped after an audit.
7. NoGood
Best fit: Growth-stage and larger brands that want AEO connected with content, earned media, social and broader growth work.
NoGood uses the AEO label, but the practical scope overlaps heavily with GEO. Its AEO service includes prompt research, competitive analysis, content development, technical audits, schema, site architecture, earned media, reputation work and monitoring across major AI platforms.
This is one of the broader public scopes in the comparison. NoGood also states that it uses Goodie AI, an external platform, for visibility monitoring. That disclosure is helpful. Buyers can separate the agency’s strategy and execution from the software used to observe results.
The page says timelines depend on the starting point and that movement may begin within a few months. Treat that as general guidance, not a delivery commitment. Prompt volatility and uneven citation behavior make universal timelines unreliable.
What to verify: which deliverables are produced by NoGood versus the tracking platform, how off-site work is disclosed, and what the proposed team has done in the buyer’s category.
Pricing: not published on the AEO service page reviewed.
8. Omniscient Digital
Best fit: B2B software companies that need content-led SEO and AEO tied to organic pipeline.
Omniscient Digital does not present the same standalone public GEO service page as several firms above. Its evidence appears through its organic-growth positioning and verified client reviews.
On Clutch’s Omniscient Digital profile, a verified 2026 review describes technical audits, content briefs, link building and AEO monitoring for an AI software company. Another verified review for Convert describes a program covering a content roadmap, LLM optimization, content production and PR. The directory lists generative engine optimization among the agency’s SEO capabilities.
That makes Omniscient a credible candidate for B2B content programs, but buyers should not infer a standardized GEO product from the directory alone. Ask to see the actual AEO scope, reporting and team proposed for the account.
What to verify: prompt-tracking methodology, technical implementation, the division between SEO and AEO deliverables, and a current example of AI-visibility reporting.
Pricing: Clutch lists a $5,000 minimum project size. That is a directory profile minimum, not a quoted price for a full GEO engagement.
9. First Page Sage
Best fit: B2B organizations that want thought leadership, organic content and GEO managed as one lead-generation program.
First Page Sage positions SEO and GEO together and emphasizes expert content, lead generation and long-term brand visibility. It also publishes extensive agency rankings and market research about GEO.
Those materials demonstrate commitment to the category, but much of the supporting evidence is self-published. Its agency rankings score First Page Sage highly, and its 2026 pricing report describes a large proprietary dataset. Buyers should ask for the underlying methodology, client references and examples that can be examined beyond the company’s own editorial properties.
The firm may suit teams that value a thought-leadership publishing program over a narrowly technical engagement. The public site is less explicit than some competitors about prompt sets, raw visibility access and platform-specific reporting.
What to verify: the exact GEO deliverables, reporting sample, named implementation team, third-party authority work and client evidence relevant to the buyer’s industry.
Pricing: not publicly disclosed on the pages reviewed.
10. Single Grain
Best fit: Companies seeking a broad program spanning content, technical GEO, digital PR, local presence and conversion optimization.
Single Grain’s GEO service covers question and prompt research, AI-citable content, technical structure, entity work, digital PR, community distribution, local visibility, conversion optimization and reporting. Few firms on this list describe such a wide scope on one page.
Breadth can be an advantage if the proposed team truly owns each discipline. It can also produce a shallow engagement if the retainer is spread across too many workstreams. The proposal should make the monthly output and accountable specialists clear.
Single Grain says it measures share of answer, citations, prompt coverage, conversions and revenue. Ask to see how those measures appear in an actual client report and how it handles traffic that arrives without a clean AI referrer.
What to verify: named specialists, monthly deliverables, the balance between owned content and authority building, attribution rules and whether conversion optimization is included or separately scoped.
Pricing: not publicly disclosed.
Five questions that expose a weak GEO proposal
Which prompts will you track, and who approves them?
“We monitor thousands of prompts” can be less useful than a carefully governed set of 100. The agency should explain how it found the prompts, which buying stage each represents, how branded prompts are treated and how the set will change without destroying the baseline.
Ask to see the prompt list before the engagement starts. If it contains only broad informational questions, it may create an impressive visibility chart with little commercial relevance.
How do you handle volatility?
AI answers vary by engine, time, model, location, account state and phrasing. One screenshot is not a baseline. A serious method repeats tests under stated conditions, stores the raw answers and reports trends rather than celebrating a single mention.
The agency should also distinguish a citation from a brand mention. A source can be cited without the brand being recommended, and a brand can be named without receiving a link.
What will you change outside our website?
Owned content matters, but answer engines also retrieve publishers, communities, reviews, directories, videos and other third-party sources. Ask which off-site surfaces matter in your category and how the agency will work there.
The answer should include governance. Undisclosed promotion, fake reviews and manufactured community activity are not authority strategies.
How will visibility connect with a business outcome?
AI referral traffic is useful when it can be identified, but referrer data is incomplete. A practical measurement plan can also use landing-page cohorts, self-reported attribution, CRM source capture, assisted conversions and branded-demand changes. None is perfect alone.
This is where Black Propeller’s paid-search service and SEO service can inform a combined program: query and conversion data help decide which themes deserve attention. The same principle applies whichever agency is hired.
What exactly will we own?
The contract should state who owns the prompt set, research, content, dashboards, schema, digital assets and accounts. It should also explain what remains accessible after termination. A buyer should not lose its measurement history because an agency relationship ends.
What GEO pricing can honestly tell you
The market does not yet support a reliable universal price band from the public pages of these ten firms. Most quote after discovery, and directory minimums often apply to any service line rather than GEO specifically.
Instead of comparing one headline retainer, compare the work underneath it:
- number of tracked prompts and engines
- frequency of testing
- access to raw responses and exports
- technical audit and implementation
- content strategy, production and refreshes
- digital PR and placement costs
- community or review work
- analytics and CRM integration
- reporting and strategy time
- contract length and asset ownership
A $7,500 retainer that covers monitoring and advice is not cheaper than a $15,000 retainer that includes engineering, content and authority building. They are different products.
Ask each shortlisted agency to price the same 90-day problem. For example: establish a baseline across an agreed prompt set, correct the most important technical barriers, improve five existing commercial pages, build one evidence-led asset, pursue relevant third-party coverage and show the resulting changes in visibility and qualified activity. The responses will be far easier to compare than generic monthly packages.
Frequently asked questions
What is the difference between GEO and AEO?
There is no settled industry boundary. GEO is usually used for visibility, citations and brand representation in generative answers. AEO is often used for direct answers across AI assistants, featured snippets, voice and other answer surfaces. Many agencies use the terms interchangeably or combine them. Compare deliverables, not labels.
How long does GEO take?
There is no responsible universal timeline. Technical access changes may be reflected sooner than authority-building work. An existing high-authority brand may move faster than a new site with little third-party evidence. Ask for a review cadence and leading indicators, not a guaranteed citation date.
Can an agency guarantee that ChatGPT will recommend a company?
No. AI answers are probabilistic and can vary across runs and users. An agency can improve the quality, accessibility and authority of the evidence available to an engine. It cannot guarantee a fixed recommendation in an independently operated product.
Should GEO replace SEO?
No. Crawlability, site architecture, useful content, authority and measurement support both conventional and AI-mediated discovery. A GEO plan should identify what is genuinely new while preserving the search work that already produces qualified demand.
What should a GEO report contain?
At minimum: the tracked prompt set, engines and testing method; citation and mention trends; competitors appearing for the same prompts; source URLs used by the engines; completed work; AI referral behavior where observable; and the connection to conversions, pipeline or another agreed business result.
Build the shortlist around your actual constraint
Choose iPullRank for a technical enterprise operating model, Siege Media for content and citation-graph execution, Directive for B2B demand, Go Fish Digital for passage-level and ecommerce work, or one of the other specialists when its operating model matches the job.
Choose Black Propeller when the problem crosses GEO, SEO, paid media, landing pages and conversion data, and one team needs to decide how those signals work together.
Before hiring anyone, ask for the prompt set, a sample report, a 90-day scope, the named team and the evidence behind any performance claim. The quality of those five items will tell you more than the agency’s position on this or any other list.
To see which brands AI engines currently surface for your buyers’ questions, request a GEO review from Black Propeller.
A GEO agency can sound convincing long before it has proved that it can change what an AI answer says.
The vocabulary is easy to borrow: prompt tracking, citation share, entity optimization, answer visibility. The harder questions come later. Which prompts will the agency monitor? How will it separate a fleeting mention from a repeatable gain? Who will fix the site, create the evidence, earn third-party coverage and connect AI referrals with pipeline?
That is where the firms on this list differ.
We reviewed the public GEO or AEO service material, measurement claims, case studies, commercial information and client fit of US GEO agencies active in AI search. The ranking favors firms that can execute the work, not merely report visibility from a software dashboard.
Disclosure: Black Propeller publishes this article and is included in the ranking. That conflict is unavoidable, so the evidence standard is stated below and gaps are left visible. “Not publicly disclosed” means exactly that; it is not replaced with an estimate.
The shortlist

| 10 | Single Grain | Brands wanting GEO combined with content, PR, local presence and conversion work | Broad GEO service with prompt research, technical work, distribution and attribution | Not publicly disclosed |
There is no universal “best” GEO agency. A retailer with thousands of product pages should not buy the same program as a B2B software company with a long sales cycle. The ranking is a starting point for a shortlist, not a substitute for reviewing the proposed team, scope and evidence.
What we mean by a GEO agency
Generative engine optimization is the work of improving whether, where and how a brand or source appears in AI-generated answers.

Black Propeller has also published results from its own site through a Pixis customer story. The reported program reorganized the blog into topic clusters, mapped content against tracked prompts and combined content work with technical changes. Because Pixis and Black Propeller are part of the same wider group, buyers should treat this as first-party evidence, not an independent case study.

4. Directive
Best fit: B2B companies that want GEO framed around buyers, demand and pipeline.
Directive’s B2B GEO service covers entity and topic mapping, content optimization, structured data, technical work and visibility reporting. The public methodology is explicitly aimed at B2B discovery across ChatGPT, Claude, Perplexity, Gemini, Copilot and Google’s AI surfaces.
Its positioning will be familiar to B2B marketing teams: organize work around personas, long-tail buying questions and pipeline influence rather than treating every mention as equally valuable.

6. Victorious
Best fit: Mid-market and enterprise teams that want GEO incorporated into an established SEO program.
Victorious presents GEO as an extension of SEO rather than a separate replacement. Its GEO service page covers entity clarity, extractable content, third-party authority and visibility across multiple AI platforms.

7. NoGood
Best fit: Growth-stage and larger brands that want AEO connected with content, earned media, social and broader growth work.
NoGood uses the AEO label, but the practical scope overlaps heavily with GEO. Its AEO service includes prompt research, competitive analysis, content development, technical audits, schema, site architecture, earned media, reputation work and monitoring across major AI platforms.

Pricing: not published on the AEO service page reviewed.
8. Omniscient Digital
Best fit: B2B software companies that need content-led SEO and AEO tied to organic pipeline.
Omniscient Digital does not present the same standalone public GEO service page as several firms above. Its evidence appears through its organic-growth positioning and verified client reviews.
On Clutch’s Omniscient Digital profile, a verified 2026 review describes technical audits, content briefs, link building and AEO monitoring for an AI software company. Another verified review for Convert describes a program covering a content roadmap, LLM optimization, content production and PR. The directory lists generative engine optimization among the agency’s SEO capabilities.
That makes Omniscient a credible candidate for B2B content programs, but buyers should not infer a standardized GEO product from the directory alone. Ask to see the actual AEO scope, reporting and team proposed for the account.
What to verify: prompt-tracking methodology, technical implementation, the division between SEO and AEO deliverables, and a current example of AI-visibility reporting.
Pricing: Clutch lists a $5,000 minimum project size. That is a directory profile minimum, not a quoted price for a full GEO engagement.
9. First Page Sage
Best fit: B2B organizations that want thought leadership, organic content and GEO managed as one lead-generation program.
First Page Sage positions SEO and GEO together and emphasizes expert content, lead generation and long-term brand visibility. It also publishes extensive agency rankings and market research about GEO.
Those materials demonstrate commitment to the category, but much of the supporting evidence is self-published. Its agency rankings score First Page Sage highly, and its 2026 pricing report describes a large proprietary dataset. Buyers should ask for the underlying methodology, client references and examples that can be examined beyond the company’s own editorial properties.
The firm may suit teams that value a thought-leadership publishing program over a narrowly technical engagement. The public site is less explicit than some competitors about prompt sets, raw visibility access and platform-specific reporting.
What to verify: the exact GEO deliverables, reporting sample, named implementation team, third-party authority work and client evidence relevant to the buyer’s industry.
Pricing: not publicly disclosed on the pages reviewed.
10. Single Grain
Best fit: Companies seeking a broad program spanning content, technical GEO, digital PR, local presence and conversion optimization.
Single Grain’s GEO service covers question and prompt research, AI-citable content, technical structure, entity work, digital PR, community distribution, local visibility, conversion optimization and reporting. Few firms on this list describe such a wide scope on one page.
Breadth can be an advantage if the proposed team truly owns each discipline. It can also produce a shallow engagement if the retainer is spread across too many workstreams. The proposal should make the monthly output and accountable specialists clear.
Single Grain says it measures share of answer, citations, prompt coverage, conversions and revenue. Ask to see how those measures appear in an actual client report and how it handles traffic that arrives without a clean AI referrer.
What to verify: named specialists, monthly deliverables, the balance between owned content and authority building, attribution rules and whether conversion optimization is included or separately scoped.
Pricing: not publicly disclosed.
Five questions that expose a weak GEO proposal
Which prompts will you track, and who approves them?
“We monitor thousands of prompts” can be less useful than a carefully governed set of 100. The agency should explain how it found the prompts, which buying stage each represents, how branded prompts are treated and how the set will change without destroying the baseline.
Ask to see the prompt list before the engagement starts. If it contains only broad informational questions, it may create an impressive visibility chart with little commercial relevance.
How do you handle volatility?
AI answers vary by engine, time, model, location, account state and phrasing. One screenshot is not a baseline. A serious method repeats tests under stated conditions, stores the raw answers and reports trends rather than celebrating a single mention.
The agency should also distinguish a citation from a brand mention. A source can be cited without the brand being recommended, and a brand can be named without receiving a link.
What will you change outside our website?
Owned content matters, but answer engines also retrieve publishers, communities, reviews, directories, videos and other third-party sources. Ask which off-site surfaces matter in your category and how the agency will work there.
The answer should include governance. Undisclosed promotion, fake reviews and manufactured community activity are not authority strategies.
How will visibility connect with a business outcome?
AI referral traffic is useful when it can be identified, but referrer data is incomplete. A practical measurement plan can also use landing-page cohorts, self-reported attribution, CRM source capture, assisted conversions and branded-demand changes. None is perfect alone.
This is where Black Propeller’s paid-search service and SEO service can inform a combined program: query and conversion data help decide which themes deserve attention. The same principle applies whichever agency is hired.
What exactly will we own?
The contract should state who owns the prompt set, research, content, dashboards, schema, digital assets and accounts. It should also explain what remains accessible after termination. A buyer should not lose its measurement history because an agency relationship ends.
What GEO pricing can honestly tell you
The market does not yet support a reliable universal price band from the public pages of these ten firms. Most quote after discovery, and directory minimums often apply to any service line rather than GEO specifically.
Instead of comparing one headline retainer, compare the work underneath it:
- number of tracked prompts and engines
- frequency of testing
- access to raw responses and exports
- technical audit and implementation
- content strategy, production and refreshes
- digital PR and placement costs
- community or review work
- analytics and CRM integration
- reporting and strategy time
- contract length and asset ownership
A $7,500 retainer that covers monitoring and advice is not cheaper than a $15,000 retainer that includes engineering, content and authority building. They are different products.
Ask each shortlisted agency to price the same 90-day problem. For example: establish a baseline across an agreed prompt set, correct the most important technical barriers, improve five existing commercial pages, build one evidence-led asset, pursue relevant third-party coverage and show the resulting changes in visibility and qualified activity. The responses will be far easier to compare than generic monthly packages.
Frequently asked questions
What is the difference between GEO and AEO?
There is no settled industry boundary. GEO is usually used for visibility, citations and brand representation in generative answers. AEO is often used for direct answers across AI assistants, featured snippets, voice and other answer surfaces. Many agencies use the terms interchangeably or combine them. Compare deliverables, not labels.
How long does GEO take?
There is no responsible universal timeline. Technical access changes may be reflected sooner than authority-building work. An existing high-authority brand may move faster than a new site with little third-party evidence. Ask for a review cadence and leading indicators, not a guaranteed citation date.
Can an agency guarantee that ChatGPT will recommend a company?
No. AI answers are probabilistic and can vary across runs and users. An agency can improve the quality, accessibility and authority of the evidence available to an engine. It cannot guarantee a fixed recommendation in an independently operated product.
Should GEO replace SEO?
No. Crawlability, site architecture, useful content, authority and measurement support both conventional and AI-mediated discovery. A GEO plan should identify what is genuinely new while preserving the search work that already produces qualified demand.
What should a GEO report contain?
At minimum: the tracked prompt set, engines and testing method; citation and mention trends; competitors appearing for the same prompts; source URLs used by the engines; completed work; AI referral behavior where observable; and the connection to conversions, pipeline or another agreed business result.
Build the shortlist around your actual constraint
Choose iPullRank for a technical enterprise operating model, Siege Media for content and citation-graph execution, Directive for B2B demand, Go Fish Digital for passage-level and ecommerce work, or one of the other specialists when its operating model matches the job.
Choose Black Propeller when the problem crosses GEO, SEO, paid media, landing pages and conversion data, and one team needs to decide how those signals work together.
Before hiring anyone, ask for the prompt set, a sample report, a 90-day scope, the named team and the evidence behind any performance claim. The quality of those five items will tell you more than the agency’s position on this or any other list.

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.
