AI SEO Companies: What to Check Before You Hire One
The AI SEO companies worth hiring show you, before any work starts, how they will measure whether ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews name your business, explain each change in plain words, and promise you no rankings. Use those three tests and most proposals sort themselves out in one meeting.
The cost of a bad pick is months of fees for work you can't check, while buyers in your town ask an AI engine who to call and hear someone else's name.
Key points
- Ask any AI SEO company for a dated baseline first: which buyer questions, which engines, who gets named and which pages get cited.
- Walk away from guarantees. Google says no one can guarantee a #1 ranking in its own results, and no outside firm sets what an AI engine writes.
- Get every change in writing, so you can check what was done and whether the answers moved.
Why are more owners shopping for AI SEO companies?
Because their customers changed how they ask. In BrightLocal's 2026 consumer survey of 1,002 US adults, 45% said they had used ChatGPT or another generative AI tool for local recommendations, up from 6% the year before. In the same survey, 40% said they trust AI platforms to provide business recommendations.
BrightLocal's own advice to businesses is to "Monitor how your business appears in AI-generated recommendations and summaries." Ask any firm to show you that monitoring first.
What does an AI SEO company actually do?
An AI SEO company works on how your business shows up in answers from engines like ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews. The work falls into three jobs: measuring which businesses those answers name and cite, fixing your site and outside listings, and producing content. Ask which of the three a firm actually does.
Be careful with a plan for Google that is mostly new files. Google's guidance on AI features says "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." It adds: "You don't need to create new machine readable files, AI text files, or markup to appear in these features." That guidance covers Google's features only. It says nothing about how ChatGPT or Perplexity choose sources, so ask the firm what each item in its plan is for, engine by engine.
Which kind of AI SEO company fits your business?
Pick by who will make the changes and whether you can check the work.
| Type | What you get | Fits you when | Watch for |
|---|---|---|---|
| Audit and recommendations | A measured baseline across engines and a ranked list of fixes | You or your web person can make the changes | Fixes with no clear owner or order |
| Full-service agency | Measurement plus the site, listing and content work done for you | Nobody in-house has time | A long contract signed before any baseline exists |
| Software tool | Dashboards that run questions on a schedule | You have time to read data and act on it | Tracked questions that don't match how your buyers ask |
| Do it yourself | Your own tracking sheet and edits | You'll rerun the same questions each month | Too few questions to show a trend |
What should you ask an AI SEO company before you hire it?
- Which engines and which questions will you test? Ask to see the question list. It should use your buyers' wording and name your town or region.
- What does my baseline look like today? Expect a dated record of who each engine names and which pages it cites, taken before any changes.
- How do you separate mentions from citations? A mention is your name in the answer. A citation is a link to a page the answer used as a source. They call for different fixes.
- Can ChatGPT's search crawler reach my site? OpenAI's crawler documentation says "Sites that are opted out of OAI-SearchBot will not be shown in ChatGPT search answers." A firm should check your robots.txt and firewall for this early.
- Will you share every change you make? Google's guide to hiring an SEO suggests asking: "Will you share with me all the changes you make to my site".
- What results do you expect, by when, and how will you measure them? The same Google guide lists this question. An honest answer names the measurement, not a promised position.
- What's your experience in my industry and my city? Also from Google's list.
- What won't you do? A clear answer tells you where the firm's scope ends.
What are the red flags?
- Guarantees. Google states, "No one can guarantee a #1 ranking on Google." It also warns: "Beware of SEOs that claim to guarantee rankings, allege a 'special relationship' with Google". Apply the same test to anyone promising you a spot in ChatGPT's answers.
- Cold pitches. Google's guide says, "Be wary of SEO firms and web consultants or agencies that email you out of the blue."
- Secrecy. "Be careful if a company is secretive or won't clearly explain what they intend to do."
- Results you can't check. A large percentage gain means little without the starting number, the date range and the engine it was measured on.
- Ranked lists from sellers. Before you trust a "best AI SEO companies" list, check who published it. If the publisher sells AI SEO services or software, treat the order as marketing.
How do you compare two proposals side by side?
Hypothetical example: An accounting firm gets two proposals. Firm A promises the practice will "be recommended by ChatGPT within 90 days" and asks for a 12-month contract. Firm B proposes to run 25 buyer questions across ChatGPT, Perplexity, Gemini and Google AI Overviews, hand over the dated results, and list fixes in priority order with who does each one. Only Firm B gives the owner something to check in month two, and Firm A's promise is the kind of guarantee Google tells owners to avoid.
Can you check some of this yourself first?
Yes, and it makes every sales call shorter. Run your own baseline with the method in How to Rank in ChatGPT When Customers Ask Who to Hire, then work through the fixes in Answer Engine Optimization: Checks to Run This Week. You'll walk into each meeting knowing your gaps, so you can tell whether a proposal addresses them or just sounds good.
If you'd rather have that baseline done for you, Vector Index audits how ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews describe your business and gives you a written report on where you appear and which changes to make first. You can see what a Vector Index audit covers, then take that report into your first call with any AI SEO companies you're weighing.
FAQ
What do AI SEO companies do differently from regular SEO firms?
They measure and work on how AI engines describe and cite your business, not only where your pages rank in a list of links. Much of the groundwork overlaps: crawlable pages, clear service descriptions and accurate listings.
How much do AI SEO services cost?
There's no standard price, and quotes cover very different scopes. Ask each firm which jobs are included (measurement, fixes, content) and what you'll receive each month before comparing totals.
Can an AI SEO company guarantee ChatGPT will recommend me?
No. Google says no one can guarantee a #1 ranking in its results, and no outside firm controls the answers ChatGPT writes. Treat any guarantee as a reason to keep looking.
Do I need llms.txt or special schema to show up in AI answers?
For Google AI Overviews and AI Mode, Google says you don't need new machine readable files, AI text files or special schema. If one of the AI SEO companies you're talking to recommends these files, ask which engine they're for.
