Best AI SEO agencies in 2026
Four established SEO agencies that added AI-search work on top of ranking work, reviewed on proof, scope and what their numbers actually measure.
Four established SEO agencies added AI-search work on top of ranking work they already sold, rather than being built around it. This list reviews all four on the same terms — proof, scope and what their headline numbers measure — because a large traffic percentage and an AI-citation count are not the same claim.
If you want agencies built around AI visibility from day one instead, see the best GEO agencies; either way, how to choose a GEO agency sets out the criteria before any shortlist.

What separates this list from a list of GEO specialists?
History and scope. Every agency below sold SEO first and added AI-search work to that practice, usually inside the last two years. That is a reasonable path — SEO and GEO share crawlability, structured data and quotable content as raw material — but it means the AI-search claim on the page is layered onto a business built to sell something else.
| Agency | Published price | Headline proof | Main weakness |
|---|---|---|---|
| Thrive | No | Company-wide AI-platform traffic growth of +5,556% in 2025, three named case studies | Headline number is blended across every client, not one traceable account |
| Victorious | No | Named clients (SoFi, GE Digital, Delta Dental), 600+ brands served, 183+ awards | Case numbers measure organic ranking and traffic, not AI citations specifically |
| Amsive | No | Data partnership with an LLM-visibility vendor, named contributors, client examples in banking and healthcare | No dedicated AEO case study with a number attached to a named client |
| GR0 | No | $1B+ in claimed client revenue, named e-commerce case studies | "GEO" is listed as one service among a dozen, with no detail behind it |
How were these four agencies chosen and checked?
We started from a longer list of established SEO agencies that mention AI search, AI Overviews, ChatGPT or generative-engine optimization anywhere on their site, then kept only the ones with a dedicated page for that work — not the phrase dropped into a longer services list with nothing behind it. That filter alone removed more than half the original list.
For the four that remained, we read the same three things on each one's own site: the dedicated AI-search page, any case study or named client attached to it, and whether a price or pricing structure appeared anywhere near that page. We did not call any of the four or request a proposal. Everything in the table above comes from what is publicly checkable, which is also what your own first pass at a shortlist would turn up.
We are not neutral judges here. RankPearl sells GEO work too, which is exactly why this comparison sticks to what is checkable on each agency's own page rather than a subjective score. Read the source for each row yourself before you shortlist anyone, including us.
Thrive: the biggest numbers, blended across every client
Thrive's AI SEO page reports a 5,556% increase in total AI-platform traffic across its client base in 2025, broken down further into a 1,078% increase attributed to ChatGPT and 404% to Gemini [1]. Three named clients — a medical group, a footwear company and a hyperbaric treatment center — get individual case studies with their own numbers, including a 2,658% increase in Google AI Overview citations for one of them.
Those are real figures on a real page, and the individual case studies are the more useful evidence of the three. The company-wide percentage is harder to weigh without knowing the starting base: a small number of AI-platform visits growing by thousands of percent can still be a small number of visits. Ask which client the company-wide figure includes and whether your account size resembles the ones in the case studies before you take the headline number as a forecast for yours.
Victorious: enterprise clients, but the numbers are mostly about ranking
Victorious names real enterprise clients — SoFi, GE Digital, Delta Dental, Wayfair, Salesforce among them — and backs the relationship with awards (183-plus, including five wins as Search Agency of the Year) and account-level metrics: SoFi reaching 11,900 page-one keywords, GE Digital's organic traffic rising 104% [2]. AEO and AI-citation work is folded into the same service description as SEO, content and technical work.
The case studies are convincing evidence of ranking performance. They are weaker evidence of AI-citation performance specifically, because keyword position and organic traffic are what they measure, and independent tracking has found that ranking and being cited by an AI model overlap only partly.
1% to 5%
If you are evaluating Victorious or a similarly ranking-led agency for AI-search work specifically, ask them directly for a citation number, not a keyword-position number, before assuming the second buys you the first.
Amsive: a genuine data partnership, no dedicated case study
Amsive's answer-engine-optimization guide is long, detailed and, unusually for a services page, mostly educational rather than a pitch [3]. It discloses a data partnership with an LLM-visibility analytics vendor and names two well-known search practitioners as contributors, which is a real, checkable credential most pages here do not offer.
What it does not offer is a single case study that attaches an AI-citation number to a named client. The examples mentioned — banking, healthcare and SaaS accounts — are described for competitive positioning, not with a before-and-after figure. Strong credentials and a missing case study are not a contradiction; they simply mean you should ask for the number directly rather than assume it exists because the write-up is thorough.
GR0: "GEO" as one line, with nothing behind it
GR0 is a performance-marketing agency built around paid social, Google Ads, email and SMS, content and TikTok Shop management, with more than a billion dollars in claimed client revenue across named e-commerce accounts [4]. "GEO" appears once in its service list, with no page, no method and no case study behind the word.
That is the pattern worth watching for across this whole category: a term that has become common enough to list without having to explain. If an agency's AI-search offer is one word in a longer menu, the fair question is not whether they are lying — they may run real campaigns for clients who ask — but whether anyone on the account has done this work before yours, and what they would actually track for you in the first month.
What should disqualify one of these four, whatever their numbers say?
Two things, regardless of how strong the case studies look. The first is a page that will not name a single client next to a specific number — a company-wide percentage with no account attached to it is not verifiable by you, only by the agency that produced it. The second is silence on reporting: if the page that sells the AI-search work does not say what you would actually see each month, that gap tends to show up again after you sign, not before.
Neither disqualifier is about the size of the agency or the size of the number on the page. A smaller shop with one named, checkable result is a safer bet than a larger one with an impressive blended figure and nothing you can independently confirm. Ask each finalist for the account that most resembles yours in size and industry, and judge the answer, not the headline.
Price silence, on its own, is not a disqualifier — it is the market norm here, as the table above shows. Treat it as a reason to ask early, not a reason to rule an agency out before you have asked.
What this comparison can't settle for you
None of these four agencies publish a price, which matches the pattern across the wider industry: what SEO costs found the same reluctance to quote a number in public. That means every one of these four requires a call before you know whether the engagement fits your budget at all, which is worth doing early rather than after a proposal.
It also means this comparison cannot tell you which agency would actually get you cited, because none of the four case studies reviewed here isolate that specific outcome with a method attached the way a fully worked GEO result should. Treat every number on every page above, including ours, as a claim to verify in the first call rather than a result to trust from the page alone.
Whichever name you shortlist from here, bring the same list of questions to ask a GEO agency to that call. It is written to work against any of the four above, or against us.
Questions people also ask
What's the difference between this list and the best GEO agencies list?
This one reviews established SEO agencies that added AI-search work on top of ranking work they already sold. The GEO list reviews agencies built around AI visibility from the start. Some buyers want the first kind because they already trust the agency's SEO results; some want the second because the whole team is built around the newer problem.
Do any of these four publish a price?
No. All four route a visitor to a form, a call or a proposal. That is the norm across this market, not an exception — see how SEO pricing works for the pattern across the wider category.
Is a big traffic-growth percentage a reliable way to pick an agency?
Not on its own. A blended, company-wide number and a single client's traceable before-and-after are different claims, and both get shown as proof. Ask which one you are looking at, and ask for the client's name.
Does ranking well in Google mean you're also being cited by ChatGPT?
Only partly. Independent tracking found only a small share of the URLs ChatGPT and Gemini cite also rank in Google's top ten, so an agency's organic-ranking case study is not proof of AI-citation performance, even when both numbers sit on the same page.
Why does RankPearl appear in the FAQ and not the main table?
Because we are not a full-service agency that added AI search onto an established ranking practice — we are a smaller shop built with GEO as a named service from the start, which puts us on the companion list of GEO specialists instead.
