A quick note before the list: the earlier version of this page included our own agency and a sister company in the ranking, presented as an independent "best of" list. That's not transparent, and it's not useful to you. We've pulled our own company out of this list entirely. If you want to talk to us, there's a contact link at the bottom, clearly labeled as that, not disguised as an objective number one ranking.
What follows is a look at how to actually evaluate an AI SEO agency, plus a rundown of several established, independently verifiable agencies that do real work in this space (not ranked against each other, since "best" depends entirely on your budget, industry, and goals).
What "AI SEO" actually means right now
Be skeptical of any agency slapping "AI SEO" on services that are just ordinary SEO with a new label. The legitimate version of this work usually covers three things. First, technical groundwork that makes your content easy for both search crawlers and AI systems (like the ones powering ChatGPT, Perplexity, and Google's AI Overviews) to read and understand, things like clean HTML structure, schema markup, and fast page loads. Second, content written to directly answer specific questions, since both traditional featured snippets and AI-generated answers favor content that states a clear answer early rather than burying it under three paragraphs of preamble. Third, authority building: getting your business mentioned, reviewed, and linked to across the web in ways that build the kind of trust signals these systems weigh when deciding what to cite.
If an agency's pitch is just "we use AI to write your content faster," that's a production efficiency claim, not an AI SEO strategy. Those are different things, and conflating them is one of the biggest red flags in this space.
How to evaluate an agency, step by step
Ask for a client example in your industry or a comparable one, with actual before and after data: traffic, rankings, or leads, not just "we improved their visibility." Ask how they measure AI Overview or AI chatbot citations specifically, since this is genuinely hard to track and a good agency should have an honest answer about their process and its limitations, rather than a confident-sounding made-up metric. Ask for a sample report so you know what you'll actually receive monthly. And ask directly what they do differently for AI search versus traditional SEO; if the answer is vague, that's worth noting.
Get a contract length and pricing structure in writing before signing anything, and be wary of anyone guaranteeing a specific ranking or a guaranteed appearance in an AI Overview. Nobody controls that outcome completely, including Google and OpenAI's own algorithms, which change constantly.
Agencies doing established, verifiable work in this space
These are agencies with a public track record you can research independently. We're not vouching for any of them as individually "best," and we have no financial relationship with any of them. We're simply naming established players whose work is a matter of public record so you have real reference points.

Victorious SEO structures its engagements around specific revenue or business goals rather than ranking positions alone, which is a reasonable way to keep an engagement honest.

You'll find other "AI SEO agency" roundups online that include small or newly formed companies with no independently verifiable track record, sometimes written by those same companies or their marketing partners. There's nothing wrong with a smaller or newer agency doing good work, but you should be able to verify claims yourself: ask for references you can actually contact, look up the agency's history, and don't take a "top 10" list's word for it, including this one.
The bottom line
The right AI SEO agency for you depends on your size, budget, and industry, and no single list can hand you that answer honestly. Use the evaluation questions above in every sales call, ask for verifiable proof rather than confident claims, and treat any "best of" list, this one included, as a starting point for research rather than a final answer.
Questions worth more than a sales call
A real conversation with any shortlisted agency should cover three things: which specific KPIs they will report on monthly, what their process looks like when a client site drops in AI visibility after a model update, and whether the team working on your account has done this for a business your size before. An agency that answers all three clearly, without retreating into generic marketing language, is worth a second meeting.
One more thing worth checking directly: ask to see a client dashboard or sample report, not a sales deck. The difference between what an agency promises in a pitch and what they actually deliver each month usually shows up fastest in their reporting.
