Best AI SEO Agencies 2026: 15 GEO and AEO Firms Ranked

A disclosure, before anything else

We are on this list, and we put ourselves first. So read this as our argument rather than a neutral verdict, and use the test at the end to check it. Every fact about another agency here was read off that agency’s own website in August 2026, and anything we could not confirm is marked UNVERIFIED rather than guessed.

Here is why we think the argument holds anyway. Almost every “best GEO agency” article is written by whoever sits at number one, and most of them hide that. We would rather state it, publish the criteria, publish our own weaknesses, and let you compare. Every claim below about another agency is something we fetched from their own website in August 2026. Where we could not verify something, the table says UNVERIFIED rather than guessing.

Do you actually need a GEO agency right now?

Probably not, if nobody is searching for your category in AI tools yet. Run your top buyer question through ChatGPT and Perplexity before you spend anything. If a competitor gets named and you do not, you have a gap worth paying to close. If the engines return vague, generic answers with no brands, the category is not being answered yet and your money is better spent elsewhere.

You can also do a meaningful amount yourself. Adding direct-answer sections, publishing genuine first-party data and earning a handful of third-party mentions will move simpler queries without an agency. The wall most in-house teams hit is measurement across several engines plus the off-site work, since AirOps found 85% of brand mentions in AI answers come from domains other than the brand’s own. That is the part that eats a full-time role.

How we ranked the best AI SEO agencies 2026

We deliberately scored what can be checked rather than what sounds impressive. Every criterion below is something a reader can verify on the agency’s own site in a few minutes: published pricing, named case studies with numbers, original research and a stated method for measuring AI citations. Claims we could not check score zero.

What we could not verify, and did not publish: founding years, headcount and Clutch ratings. Several profile pages block automated access, and we would rather leave a column out than fill it with numbers we did not confirm. If a comparison table anywhere shows a confident figure for all 15, ask where it came from.

Quick comparison: the top AI SEO agencies 2026 at a glance

Verified in August 2026 from each agency’s own website, not from directories, press releases or third-party listings. Where a figure or a claim was not published anywhere we could reach, the row says so rather than carrying an estimate. Prices and positioning move, so re-check anything you are about to act on.

Two agencies we removed. Terakeet and Amsive appear on other GEO lists, and both now offer AI search work: Amsive lists “SEO + AEO” among its services and Terakeet lists “Generative AI Optimization”. Neither leads with it. Terakeet’s homepage positions it as reputation management and Amsive’s as data-led performance marketing, so we kept the list to firms whose positioning centres on search.

What it actually costs

Only 7 of the 15 publish a number. Here is every figure we could verify, read off the agency’s own pricing page in August 2026. The spread is wide enough that an average would mislead, so the individual figures are listed instead, with the pricing model each one attaches to.

The spread is more than 100 times from bottom to top, from $165 a month to an average retainer above $20,000, and it does not track quality. It tracks who the agency is built to serve. A $20,000 monthly retainer is the right answer if you are defending a category. It is the wrong answer if you need six pages cited by next quarter.

The guarantee question, and why almost nobody offers one

No agency can honestly guarantee that ChatGPT will cite you. The engines own their retrieval logic and change it constantly. Anyone promising guaranteed placement in a specific answer is selling certainty that does not exist, and the wider industry treats that promise as a red flag. We agree with that.

What an agency can commit to is what it will do if the work falls short. That is a different kind of promise, and it is the only kind worth having.

Ours is deliberately not a placement promise. The 1-in-4 Guarantee covers our monthly plans. You approve 50 to 100 buyer questions in week one, we baseline them across ChatGPT, Perplexity, Gemini and Copilot, and you publish our work within 14 days of delivery. If AI engines do not name you on at least 25% of those questions within 90 days, we work the next two months free. A question counts when you appear in two of three runs. The remedy is always more work, never a refund, because a refund leaves you exactly where you started. Outside this list, Cited and KeyCrew also publish 90-day guarantees.

The 15 best AI visibility agencies, one by one

1. CiteVantage: best for small teams that want AI citation visibility without an enterprise retainer

We are an AI SEO agency working across ChatGPT, Google AI Overviews, Gemini, Perplexity and Copilot. The free audit measures where you stand on ChatGPT, Perplexity, Gemini and Copilot, the $249 one-time 30-Day Sprint fixes the gaps it finds, and monthly plans keep the work going. Our largest published dataset is the 500-Query Houston Real Estate AI Visibility Study: 2,000 AI answers in which about 94% of Houston’s roughly 50,000 Realtors were never named. An earlier study of 181 US ecommerce brands found 87% absent from all four engines it tested.

Pros: a published price ladder: a free audit, a $249 one-time Sprint, then monthly plans at $499, $999 or $1,899. The 1-in-4 Guarantee, measured on buyer questions the client approves. As of October 2026, ours is the only guarantee in this list measured on questions the client approves, with a published 25% threshold. Multi-engine measurement under a published method, with screenshots of real answers, not ranking charts. Direct access to the founder rather than an account manager. Real multi-site results, including Bright Realty International, a 17-domain international property network that reached roughly 2.1x organic clicks in three months and has 35 pages cited by AI engines.

Cons: founded in 2026, so there is no decade of references and we are the wrong call if that is your bar. Most of our published case studies are ecommerce rather than the vertical you may be in. We have no filmed client testimonials yet, so our proof is written and self-published and you should weigh it accordingly. We do not build websites. If you want a new site with MLS or ecommerce platform integration, Luxury Presence, AgentFire or a development shop will serve you better. We make the site you already have the one AI recommends. The work is done by one founder with capped intake, so there can be a wait.

On pricing, plainly: CiteVantage LLC is registered in Wyoming, and the work is founder-led from Pakistan on AI systems we built, which is why our prices sit below a comparable US agency’s. It is not a difference in method.

2. Minuttia: best for B2B SaaS entity authority

Homepage headline is “Dominate AI Search”, and the positioning is genuinely built around AI search rather than bolted on. Strong reputation in B2B SaaS content.

Pros: clear specialism, both GEO and AEO stated publicly, well regarded for depth on entity work. Cons: no published pricing, so you cannot qualify yourself before a call. No guarantee found. Narrow vertical fit if you are not B2B software.

3. iPullRank: best for enterprise technical AI search

Positions as a “Pioneering Enterprise and Mid-Market AI Search Agency”. The most technically credible name on this list for large, complex sites.

Pros: deep technical capability, genuine thought leadership, enterprise and mid-market focus stated openly. Cons: no published pricing and enterprise engagements are priced accordingly. AEO is not mentioned on the homepage. Almost certainly oversized for a small business.

4. Siege Media: best for content-led GEO at scale

Describes itself as a “Full-Service GEO Agency for Brands”. Content and digital PR heritage, now pointed at AI search.

Pros: strong content production capacity, GEO stated (AEO is not named on the homepage), real editorial quality. Cons: no published pricing. Content-led programmes need volume and time, so results are slower. Better fit for brands with existing authority than for a standing start.

5. First Page Sage: best for established B2B with long sales cycles

Titles itself simply “Best SEO Agency” and publishes a widely cited GEO agency roundup of its own.

Pros: established, publishes plenty of methodology, covers GEO and AEO. Cons: no published pricing. The “best SEO agency” framing is a claim rather than a specialism. Their roundups rank themselves highly, which is worth knowing when you read them.

6. Foundation Inc: best for B2B tech and SaaS content programmes

Homepage reads “AI Visibility Agency for B2B Tech & SaaS”, which is one of the more specific positions in this set.

Pros: clear vertical, AI visibility stated as the core service, respected content operation. Cons: no published pricing, and AEO is absent from the homepage. Not a fit outside B2B tech.

7. Loopex Digital: best for breadth of specialisms under one roof

An “SEO Agency for Growth in Search and AI” with an unusually wide service menu and, technically, the most sophisticated AI-readable setup we found anywhere: every page is available as clean markdown and there is a full-content file for language models.

Pros: excellent technical GEO implementation, strong digital PR engine, publishes at least one price. Cons: generalist rather than vertical. Their backlink profile includes a visible quantity of low-quality network links, which is worth asking about. Their real estate ranking page carries no real estate case studies behind it.

8. Stratabeat: best for B2B brand and GEO combined

An “Award-Winning B2B SEO, GEO & Content Agency” that pairs brand and design work with search.

Pros: brand plus search under one roof, GEO stated publicly, established B2B track record. Cons: no published pricing, and AEO is absent from the homepage. Regional and B2B focus limits fit.

9. Omniscient Digital: best for B2B software content programmes

An “Organic Growth Agency for B2B Software Companies” with a published entry point of $10,000 per month.

Pros: publishes pricing, which most of this tier does not. Clear vertical. Both GEO and AEO stated. Cons: the $10,000 entry point rules out most small businesses. No guarantee found. Content-led, so slow by design.

10. Growth Marshal: best for small business buyers who want published pricing

Positions around AI agents for small business. Its domains now redirect to machinelike.ai, and the tiered price list it used to publish is no longer available.

Pros: explicitly aimed at small business, and its pricing page lists GEO and content as one of the agent workloads it sells. Cons: neither GEO nor AEO appears on the homepage. The positioning leans toward AI agents rather than citation visibility specifically, so confirm the deliverable matches what you need. No guarantee found.

11. Rise at Seven: best for digital PR driven citations

An “Award Winning Search-First Content Marketing Agency” built on creative digital PR, which is a genuinely effective route to AI citations given how much of that citation layer is earned media.

Pros: the earned-media mechanism is exactly what moves AI citations, and a strong creative reputation sits behind it, with both GEO and AEO stated. Cons: there is no published pricing, and campaign-led work is unpredictable by nature. Not a technical GEO shop.

12. Single Grain: best for multi-channel revenue marketing

A “Revenue Marketing Agency” spanning SEO, paid media and AI growth, with pricing published from $10,000.

Pros: publishes pricing, broad channel coverage, well established. Cons: GEO is one service among many rather than the core. The only guarantee found relates to response times, not outcomes. Enterprise-level entry point.

13. NoGood: best for venture-backed growth teams

A growth marketing agency working with funded startups and scale-ups, with an average retainer above $20,000 per month visible in site copy.

Pros: strong growth-marketing pedigree, works with well-funded teams, AEO mentioned. Cons: the highest average retainer on this list. GEO is not stated on the homepage. Growth marketing first, AI visibility second.

14. InboundREM: best for real estate buyers who want a long track record

A real estate SEO and AEO agency publishing content since around 2017, with pricing disclosed inside its llms.txt at $750 to $2,500 per month.

Pros: by far the longest real estate track record here, roughly 750 pages of published content, an unusually strong entity setup including a machine-readable press and citation graph most agencies do not bother with. Publishes pricing. Cons: no guarantee found. GEO is absent from the homepage even though AEO is present. Real estate only, so no help outside that vertical. If you are weighing the two of us, our CiteVantage vs InboundREM comparison sets plans, terms, guarantee wording and proof side by side, each sourced and dated.

15. FlyDragon: best for real estate market-level coverage

An “AI SEO Agency for Real Estate Agents” with published pricing from $799 per month for its Town tier on a 6-month commitment (checked September 2026) up to $2,599 per month, filmed client testimonials and around 1,200 templated pages covering individual US markets.

Pros: the only competitor here with filmed, unscripted client video. Published pricing. Genuine market-by-market coverage. A market exclusivity guarantee, meaning one agent per market, and as of September 2026 a promise on its GEO service page to extend the engagement free if your AI visibility score has not moved meaningfully in 90 days. Cons: their templated market pages carry only default page and breadcrumb markup, with no agent or list structured data, and some are padded with placeholder agent entries. The stated ranking basis on those pages does not correspond to any visible field. Real estate only. The CiteVantage vs FlyDragon comparison puts price, minimum term, guarantee wording and proof next to each other, with our bias declared.

Red flags to watch for

Questions to ask any agency before you sign

Which agency should you actually pick?

If you are a small team or a single-vertical brand, start with a free audit and a fixed-scope sprint rather than a retainer. That is where CiteVantage sits and it is the argument this page exists to make. If you are running an enterprise programme with a category to own, Minuttia, iPullRank or Siege Media are better matches and we would rather tell you that than take the wrong engagement.

The honest summary of this market in 2026 is that the label moved faster than the practice. Most of the fifteen firms here mention GEO or AEO publicly, but the underlying work is often the same content and authority programme it always was. That is not a scandal, because entity authority and quotable content genuinely are the job. It just means the label tells you very little, and the only reliable filters are published pricing, measurable proof and a straight answer about what happens if it fails.

If you are in real estate specifically, we ran the same 15-agency exercise for that vertical, including which agency each of the five engines actually named, in the best AI SEO agencies for real estate agents.

We have run the same exercise for three more buyer types: real estate brokerages and teams, property management companies, and ecommerce and DTC brands. Each has a different shortlist, because the engines answer each question from different sources.

Run your top buyer question through ChatGPT and Perplexity right now. If a competitor is named and you are not, that gap is the entire brief. Our free AI visibility audit checks ChatGPT, Perplexity, Gemini and Copilot and shows you exactly who gets cited instead of you.
