Generative Engine Optimization Agencies: 10 to Consider

Generative engine optimization agencies help brands get retrieved, cited, described accurately and recommended inside AI generated answers, not just ranked in a list of links. The useful comparison isn't who promises the most mentions, it's who publishes pricing, defines deliverables and can prove change on the same prompts over time. BrightEdge reported in 2025 that 68% of organizations were actively changing their strategies in response to AI search and generative engine optimization, based on a survey of more than 750 search, content and digital marketing professionals.

Day to day, the work covers prompt and citation research, crawlability and structured data fixes, source and comparison pages, digital PR for third party mentions and repeated measurement of AI answers. Published pricing is rare, and most results are agency reported, so scope and verification matter more than claims.

That discipline matters because software answers are short and unstable. Kliqo's published research on 568 ChatGPT answers across 142 software buying questions found the top pick shifts between runs and links often go to tools' own sites, which is why citation work and repeat measurement matter for any agency on this list.

1. Go Fish Digital#

Go Fish Digital combines technical and semantic SEO, content audits and digital PR under one GEO service. The aim is to make site content easier for AI systems to interpret and cite, while strengthening brand presence on relevant external sources. Larger teams and complex sites that want a structured audit and implementation plan are the clearest fit.

What the service covers#

• Semantic content audits: topical coverage, entity signals and content structure checked for clarity and gaps.
• Digital PR: brand mentions earned on authoritative sources that AI answers may cite or draw from.
• AI Overview tooling: an analyzer and similarity score tool offered alongside the service.
• Sector range: SaaS, ecommerce, B2B, legal, healthcare and financial services work described publicly.

Buyers weighing GEO against a rebadged SEO retainer can use practical background on ChatGPT SEO fundamentals to test whether audit recommendations are specific to AI answers.

The strengths are combined technical SEO, content and PR and audit areas explained in practical terms. The limits are equally plain. Pricing is custom and not published, some tool descriptions rely on the agency's interpretation of search patents so recommendations should be tested, and methodology and reported results aren't independent proof of outcomes.

2. Siege Media#

Siege Media runs a content and authority led GEO program supported by SEO consulting, digital PR, affiliate work and Reddit. The agency says prompt and citation data identify visibility gaps, then content and coverage address them. Public client examples include agency reported AI visibility and traffic value figures, which gives buyers something concrete to question on a first call.

Its offer pairs GEO consulting informed by prompt and citation analysis with content production, SEO and digital PR. Affiliate and community channel work sit alongside that core, so the program suits brands whose citation gaps live off site. A practical check against how to get cited in Google AI Overviews helps separate citation tactics from general content volume.

A case study is useful only when the prompt set, dates and measurement method are available for review.

Pricing isn't published and depends on scope. Performance figures are agency claims, so methodology and dates should be confirmed before signing. A content and PR heavy program may also exceed the needs of a team that only wants a technical audit or crawlability fixes.

3. Relevance#

When the problem is trust rather than technical structure, Relevance is built differently. It combines digital PR, SEO and AI visibility work, including crawler access, structured data, entity clarity and earned citations. Reporting brings AI visibility together with rankings, topical authority and technical site health.

Public descriptions name work with brands including Chime, Nurx, EY and 1-800-GOT-JUNK. That breadth suggests a fit for brands that need both their own site and their third party reputation improved, rather than prompt monitoring alone.

Where it fits and where it doesn't#

• Useful when: visibility depends on third party coverage, reviews and trust signals beyond owned pages.
• Useful when: PR, SEO and content expertise need to sit under one engagement instead of three vendors.
• Less suitable when: the priority is frequent prompt level monitoring or a narrow technical fix list.
• Verify first: standard prompts, engines tracked and reporting cadence aren't specified for every client.

The agency says it discusses realistic timelines and fit before engagement, which is worth testing with direct questions. Pricing is custom, so buyers should ask what's included in the first phase and what counts as extra implementation.

4. Stratabeat#

Stratabeat targets B2B companies with GEO and AI SEO services. Published scope covers prompt research, content strategy, technical SEO, schema, entity optimization, digital PR and reporting. The agency says strategists typically manage only two to four accounts, positioning the work as closely supported rather than high volume.

Research starts with audience and prompt analysis, competitor review and visibility audits. Technical work includes schema, semantic HTML and entity optimization, while content is human written and organized around topic clusters and thought leadership using first party data. Ongoing experimentation and custom reporting round out the program.

That mix connects GEO with established SEO and content operations, which suits B2B and SaaS buyer questions and comparison content. A software team comparing alternatives pages, for example, gets one team handling both ranking and recommendation.

Pricing isn't publicly stated. Performance claims should be checked for definitions and measurement details, especially how a recommendation differs from a mention. The scope may also be extensive for a company that only needs a one off audit or a single implementation task.

5. Momentence#

Momentence narrows its focus to B2B software and SaaS brands. Rather than counting citations alone, it looks at whether AI answers include a brand in shortlists and describe it accurately. That distinction matters in software buying, where being cited for the wrong use case can be worse than being absent.

Work can address off site evidence such as reviews, comparison pages, roundups and stale or incorrect claims. The agency lists a free AI discovery snapshot and paid diagnostic options, so buyers can start with a defined deliverable.

Pricing transparency#

• Published pricing: some engagements are listed, including a standalone program starting at $4,500 per month.
• Minimum term: listed programs carry a six month minimum, so total commitment should be calculated upfront.
• Trade off: that pricing may sit beyond early stage budgets, even with the free snapshot as an entry point.

SaaS specialization may suit comparison driven buying journeys, and published pricing is more open than most providers here. Off site work may require client participation and coordination, including access to review profiles and product facts.

6. Search Engine People#

Packaging is the differentiator at Search Engine People. Its AEO and GEO packages combine prompt and competitor tracking with content optimization, technical work, schema, entity optimization and reporting. Three package levels describe different prompt and competitor volumes, with coverage including ChatGPT, Gemini, Perplexity and Google AI Overviews.

Tiers describe coverage for 50, 150 or 300 plus prompts and 3, 5 or 10 competitors. Higher levels add content and authority building support. That structure makes scope easier to compare against a custom proposal where prompt counts stay vague.

Practical rule: Compare packages on prompts tracked, engines covered and rerun frequency, not on article counts.

The package structure also combines monitoring with implementation, which may suit teams already considering traditional SEO support. There's less need to buy separate tracking if the tier includes enough prompts.

Exact package prices weren't visible in the reviewed information, so transparency stops at scope rather than cost. Engine coverage and deliverables may vary by package. A packaged service may also be less flexible than a program built for specific buyer prompts.

7. Single Grain#

Single Grain positions GEO inside broader growth work. Its service combines AI question research, citation gap analysis, content, technical SEO, digital PR, conversion optimization and performance tracking. The agency says it tracks share of answer, citations and mentions, with dashboards intended to connect visibility to traffic and business outcomes.

Research covers AI prompts, buyer questions and high intent topics. Content assets include comparison pages and Q&A content, while technical work addresses crawlability, schema, entity mapping and internal links. Digital PR and brand presence work aim to strengthen sources beyond the client's own site.

Growth teams that want GEO integrated with acquisition, rather than run as an isolated experiment, are the natural audience. The breadth covers strategy, execution and conversion in one engagement.

Pricing isn't published, and no standard package or public rate is provided. Buyers should ask directly how AI attributed traffic and leads are distinguished from other sources, since dashboards that blend channels can hide whether GEO work itself moved anything measurable.

8. 009 Agency#

Measurement comes first at 009 Agency. It offers published pricing and an audit first option, which separates it from most generative engine optimization agencies on this list. Its complimentary manual audit runs a category specific prompt panel through six engines, logs answers and sources and produces a health score and prioritized findings.

The retainer then combines measurement with technical readability, entity development, publishable content and source building work. Full cycle work re measures the same prompt panel, so before and after comparisons use matched questions rather than new screenshots. Pricing factors such as markets, languages, brands and implementation responsibilities are explained publicly.

What to verify#

• Audit ownership: the audit is described as a deliverable the buyer keeps, even without a retainer.
• Baseline scope: published pricing assumes one brand, one market and one language, and broader programs cost more.
• Honest limits: the agency identifies situations where GEO may not be a good investment.

The full cycle retainer starts at a relatively high monthly price. Audit value also depends on prompt selection and how findings translate into implementation the client team can ship.

9. HOU Digital Marketing#

HOU Digital Marketing is a Houston focused agency serving local businesses and clients seeking AI search visibility. Its GEO service covers ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews alongside SEO. Founder led strategy, month to month plans and a free strategy call shape the offer.

For a local software or services firm, local market emphasis and Houston area campaign experience may matter more than national scale. The agency publishes a starting price, with GEO services starting at $800 per month, which makes it a lower cost starting point to investigate.

It also says it will advise prospective clients if GEO isn't a priority. That claim is testable on the free strategy call by asking what should be fixed in conventional search first.

The strongest specialization appears to be Houston and local business marketing, so national SaaS teams should check relevant experience carefully. Public information doesn't show a fixed deliverables list for each GEO engagement. Buyers should confirm which prompts, engines, reporting and implementation work are included at the starting price before comparing it with packaged offers elsewhere.

10. GEO Digital#

GEO Digital is a remote first agency explicitly offering GEO, AEO and LLM optimization across ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews. Dedicated service pages cover several platforms individually, and the site offers a free GEO audit plus case studies and resources for prospective clients to review.

Clear specialization across multiple AI platforms is the main draw. A team that wants platform specific pages for ChatGPT, Gemini, Perplexity and Claude, rather than one blended AI service, can see how the agency frames each surface. Background on what generative engine optimization is helps buyers judge whether that framing matches their own buyer questions.

Remote service may suit teams that want a provider regardless of location. The audit before a paid engagement also lowers the cost of an initial conversation.

Pricing isn't published. Reviewed information is less specific about standard deliverables, measurement frequency and reporting methodology, so prospective clients should request client examples, audit scope and outcome verification details before treating case studies as proof.

GEO agencies at a glance#

How to Evaluate and Choose a GEO Partner#

Start with verification, not logos. AI answer coverage itself moves, since Semrush reported Google AI Overviews appeared for 6.49% of tracked keywords in January 2025, rose to 24.61% in July and later fell to 15.69% in November. A single screenshot can't separate agency impact from platform fluctuation.

• Written deliverables list: Require named outputs, owners and dates, not activity descriptions.
• Prompts and engines: Confirm which buyer questions are tracked, on which engines, in which markets and how often.
• Matched measurement: Demand before and after results on the same questions, with missing observations shown as missing.
• Crawlability first: Run an AI crawler checker to confirm robots.txt, sitemap and homepage access before paying for content.
• Case study checks: Verify methodology, dates, prompt wording and whether a mention meant an explicit recommendation.

Packaged engagements make scope comparison easier, while custom programs fit multi market or PR heavy needs. Baseline visibility can be checked before hiring anyone by following the steps to get recommended by ChatGPT and recording answers in a clean session.

For teams that only need measurement, Kliqo tracks nightly AI answers across ChatGPT, Google AI Overviews, Google AI Mode, Gemini and Copilot from $79 a month.

FAQ#

What does a GEO agency cost#

Published prices on this list range from $800 per month for a local starting plan to $4,500 per month for a standalone SaaS program, while most agencies quote custom. Total cost depends on prompts, markets, languages and who implements fixes.

How long until GEO shows results#

Technical fixes like crawler access can be verified immediately, but recommendation change depends on third parties publishing and engines retrieving new sources. Buyers should require repeated measurement on the same prompts rather than accept a fixed timeline promise.

Is GEO different from SEO#

Yes. SEO earns rankings and clicks, while GEO earns mentions, citations and recommendations inside generated answers that may produce no click. The work overlaps on crawlability and content quality, but measurement and off site evidence differ.

Can GEO be done without an agency#

Yes, for teams with SEO, content and PR capacity. Practical starting steps include fixing robots.txt, publishing crawlable comparison pages, getting listed on third party lists buyers trust and measuring AI answers repeatedly.

How is AI visibility measured#

Sound measurement records the exact prompt, engine, answer, brand position, sentiment, cited URLs and competitor share on every run. Repeated runs across engines and markets matter because a single answer is a sample, not a stable result.

Before paying any agency, build a baseline of the buyer questions that matter and check how AI answers describe each competitor today. Kliqo AI runs those prompts nightly across major AI engines, shows which sources get cited and separates mentions from explicit recommendations, so agency work can be judged on recorded change.
