The short answer: "AI SEO agency" means two different things. Most firms using the label are human agencies that optimize for AI search: getting your business mentioned in Google's AI Overviews, ChatGPT and similar tools. A smaller group sells SEO done by AI: software agents that do the work themselves. An AI SEO employee sits between them: AI agents doing a fixed SEO job every week, with a person overseeing the work and you approving changes. Agencies on published "best of" lists start around $1,000 a month and go well past $10,000. A small, local business usually needs the steady basics done well more than it needs an AI-search strategy team.
This page is about the AI-labeled agency decision. For choosing any SEO agency, see our SEO agency checklist. For what the work itself should include, see AI SEO services: what's included and what it costs.
What an "AI SEO agency" actually sells
Read a few agency pages and you'll find three different products under one name:
| Type | What they do | Who does the work | Typical buyer |
|---|---|---|---|
| AI-search agency (also sold as GEO or AEO) | Research the questions customers ask AI tools, rewrite pages so they answer clearly, build mentions on sites AI tools read, track whether your brand is named in AI answers | A human team, often using AI tools | Mid-size and enterprise brands |
| AI-powered agency | Traditional SEO services, delivered faster using AI tools | A human team | Any size |
| AI SEO agent or employee | Does the SEO work itself: technical checks, page fixes, listings, reports | AI agents, with a person overseeing | Small businesses wanting steady weekly work |
None of these is a scam by definition. But they're very different purchases, and the name alone won't tell you which one you're buying.
What the published lists say about cost and fit
We read the pages currently ranking for "AI SEO agency." A few useful facts from them:
- Nutshell's list of AI SEO companies says it selected agencies "offering services in the $1,000-$10,000+ per month price range" for midsize businesses (Nutshell).
- One agency on page one publishes its AI SEO pricing as $185 an hour with a 3-month minimum, and its standard SEO retainer packages from $899 a month (1Digital Agency).
- Onely, an AI SEO agency, says plainly that it "is not focused on small businesses, local search or paid media," and warns that "a place on a list of the best AI SEO agencies proves nothing, because most such lists rank their own publisher first" (Onely).
- Grow and Convert, whose list ranks first for this search, also puts itself at #1 on that list, and cites its own study of 400+ keywords showing "a 77% correlation between Google rankings and AI mentions" (Grow and Convert).
That last point matters for a small business. If ranking well in Google and being mentioned by AI tools go together, then the foundations of normal SEO are most of the AI SEO work. Google says the same thing from its side: there are "no additional requirements to appear in AI Overviews or AI Mode," and you don't need "new machine readable files, AI text files, or markup" (Google).
We're not going to rank named agencies. We haven't worked with them, and as Onely notes, most of those lists are written by agencies ranking themselves.
AI SEO agency vs AI SEO employee vs doing it yourself
| AI SEO agency | AI SEO employee (managed) | DIY with AI tools | |
|---|---|---|---|
| Best for | Brands with many pages, several markets, or a dedicated marketing budget | Small businesses needing the same SEO work done every week | Owners with time to learn and run the tools |
| Strength | Strategy, research, specialists, PR and third-party mentions | Consistency, fixed scope, fixed price, weekly reporting | Cheapest in cash |
| Weakness | Cost; often built for larger companies | Defined scope; not a strategy team or a PR firm | Your time, and no one checks the output |
| Who approves changes | Agreed in the contract | You approve pages, claims and big changes | You |
| Published pricing we found | $1,000 to $10,000+ a month on one list; $185/hour with a 3-month minimum at one agency | Ours: $599 a month per role, plus a setup fee | Tool subscriptions |
When an AI SEO agency is worth it
An agency earns its fee when:
- You sell in several markets or countries and need research on how customers in each one ask questions.
- You need third-party presence: PR, reviews and comparison pages on other sites, and community discussion that AI tools read.
- Your site is large or technically complex, and AI crawlers or Google struggle to read it.
- You have the budget for a team and someone in-house to work with them.
When an AI SEO employee is the better fit
An AI SEO employee fits when your situation looks more like this:
- One location or one service area. Your customers search for a service near them.
- The basics keep slipping. Titles, service pages, Business Profile updates, directory listings and a weekly look at the numbers never quite happen.
- You want a fixed scope and price, and you'd rather approve work than manage a team.
That's what we built Sam for. Sam is our SEO/AEO Specialist, part of Stewart Labs' digital staff. He's AI-powered, not a human employee, and a real person on our team runs your account. Every week Sam handles:
- Technical SEO: indexing, sitemap, redirects and speed flags
- On-page titles, metas, H1s, and thin or duplicate content fixes
- Local and service pages, and Google Business Profile hygiene
- AEO answer blocks and FAQs on money pages, so AI Overviews and chat assistants have clear answers to quote
- A keyword board and content briefs
- Directory listings, citations and backlink outreach
- A weekly rankings and clicks report
What Sam doesn't do: paid ads, buying links, PR campaigns, or guaranteed rankings or AI citations. You approve pages, business claims and significant site changes. The price is $599 a month per role plus a setup fee. See Sam's full role.
What that kind of work has produced on our own sites: on a small safety-training software company, fixing pages Google couldn't read and retitling pages close to page one took Google clicks from 5 to 33 a week (full write-up). On a B2B job board we run, SEO and content work together produced 650% more daily Google Search clicks over a three-month period. Your results will vary.
8 questions to ask any "AI SEO" provider
- Which kind of AI SEO do you sell: optimizing for AI search, SEO done with AI tools, or SEO done by AI agents?
- Who does the work week to week, and who checks it?
- What will you change on my site in the first 90 days? Named tasks, not "an AI strategy."
- How do you measure AI visibility? Which questions do you track, in which tools, and how often? Who chose those questions?
- What do you report besides AI mentions? Search Console clicks and impressions, plus leads where tracking allows.
- Do you sell llms.txt files, "AI schema" or special AI markup as a must-have? Google says none of that is required for its AI features.
- Do you publish AI-written content at scale? Google's guidance warns that generating many pages "without adding value for users may violate Google's spam policy on scaled content abuse" (Google).
- What do I own if we stop? Everything: domain, site, Search Console, Business Profile and content.
Our general SEO agency checklist covers contract terms and a scoring sheet, and hire an SEO expert, an agency, or an AI employee? helps if you're still choosing the type of help.
AI SEO without content stalls
Answer blocks and FAQs help, but AI tools still need useful pages to quote. If your site is thin, pair SEO with someone writing service pages and guides. That's our Content Writer role. See how SEO and content staff work together. For the bigger question of AI staff vs hiring people, read AI employee vs virtual assistant. For the full picture of SEO work, start with SEO services for small business.

FAQ
What is an AI SEO agency?
Usually a human agency that optimizes your site and brand for AI search, meaning Google's AI Overviews, ChatGPT and similar tools, alongside regular SEO. Some providers use the term for SEO done by AI agents instead. Ask which one you're buying.
How much does an AI SEO agency cost?
Published figures vary widely. One list of AI SEO companies selected agencies in the $1,000 to $10,000+ per month range, and one agency publishes $185 an hour with a three-month minimum. Our AI SEO employee is $599 a month per role plus a setup fee.
Is an AI SEO agency different from a regular SEO agency?
Mostly in emphasis. Good AI-search work rests on the same foundations: a site Google can read, clear pages that answer real questions, accurate business information, and reputable mentions. Google says there are no extra technical requirements to appear in its AI features.
Do small businesses need an AI SEO agency?
Most don't need a dedicated AI-search agency. A single-location business usually gains more from getting the basics done every week: service pages, Business Profile, listings, answer blocks and reporting. Agencies make more sense for brands with many markets or complex sites.
What is an AI SEO employee?
AI agents set up to do a defined SEO job every week, such as technical checks, page fixes, answer blocks, listings and reports, with a person overseeing the work and the business owner approving changes. At Stewart Labs, ours is called Sam.
Can an AI SEO employee get my business mentioned in ChatGPT or AI Overviews?
It can do the work that makes that more likely: clear answers on your key pages, accurate business information, and steady SEO foundations. Nobody can guarantee an AI mention or a ranking, and anyone who promises one is guessing.
