Google says in writing that you need no special markup or files to appear in AI Overviews, and that normal SEO still applies. So most of AI search is SEO your agency already does. The part that differs is off your website: how consistently the web describes your brand, which lists and reviews mention you, and whether anyone checks what ChatGPT actually says on a fixed set of questions every month. Here is how to tell whether your agency covers that.
Short answer
Your SEO agency can handle most AI search work, because Google says no special markup is needed for AI Overviews and normal SEO still applies. Hire a GEO (generative engine optimization) specialist only if your agency does not do three things: entity work, third-party mentions, and monthly tracking on a fixed prompt set. Evolve Media Agency's AI Visibility Audit is $495 and tests 50 prompts; follow-on work is fixed-price at $995, $1,995 or $3,995. Ask your agency for its prompt list first.

OpenAI crawlers that matter most here
OAI-SearchBot for search, GPTBot for training (OpenAI lists four in all)
GEO stands for generative engine optimization: getting your brand mentioned and linked inside answers from ChatGPT, Gemini, Perplexity, Claude and Google's AI Overviews and AI Mode. Our plain-English explainer covers the basics.
Google's own page on AI features and your website is blunt. It says: "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." It adds that "all existing SEO fundamentals continue to be worthwhile," and that there is "no special schema.org structured data that you need to add." To be eligible, a page must be indexed and able to show in Google Search with a snippet.
OpenAI is just as plain about ChatGPT. Its crawler documentation says OAI-SearchBot is used to show websites in ChatGPT search, and a site that blocks it will not appear in ChatGPT search answers. GPTBot, a separate crawler, collects content for training. You can allow one and block the other.
So any SEO agency that keeps your site crawlable, indexed, fast and clearly written is already doing the largest share of AI search work. If someone tells you that you need an AI-only file or a secret markup to get into AI Overviews, Google's page says otherwise.
Pages must be indexed and allowed in robots.txt (the file that tells crawlers what they may read) and by your hosting or CDN (the network that serves your pages). Google lists this first. For ChatGPT, OAI-SearchBot must not be blocked. Any competent SEO agency checks both.
AI answers quote pages that state the answer early, with names and numbers. That is good SEO writing, not a separate skill.
Google says markup should match the visible text. It helps machines read the page, but Google says no special AI markup is required.
All on Google's list. Your SEO agency should already own them.
AI answers are built from many sources at once, not just the top ten links. A model deciding "who are the best options for X" weighs what other sites say about you as much as what you say about yourself. That pushes three jobs to the front that many SEO retainers treat as optional.
An entity is how machines understand your brand as one thing: name, founder, location, what you sell, prices. If your site, Google Business Profile, LinkedIn, Crunchbase, Wikidata and directory listings disagree, models hedge or leave you out. The fix is making every one of those say the same facts. Our Wikidata guide shows one piece of it.
When ChatGPT names three agencies or three products, it often draws on roundups, review sites, forums and industry directories. Getting onto those lists, and getting accurate reviews there, is closer to PR than to link building. Classic SEO counts links; this counts mentions, with or without a link. See our brand mention strategy.
SEO reports rankings and traffic. AI search needs a fixed list of buyer questions, such as "best X for Y" or "X vs Y." Run them in ChatGPT, Gemini, Perplexity and Google AI Mode on a schedule. Record whether you are named, whether you are linked, and who is named instead. Without the same prompts each month, nobody can tell if anything improved. Our reporting dashboard post shows one way to track it.
For an ecommerce brand, the three jobs look like this in practice. Entity work means your brand name, founder, address, product line and prices read the same on your Shopify site, your Amazon brand store, your Google Business Profile and your LinkedIn page. Third-party mentions mean being named in the gift guides, comparison posts, review roundups and subreddit threads that AI tools pull from when a shopper asks for the best product in your category. Prompt tracking means a spreadsheet of the 50 questions a buyer would type, rerun every month, with a column for each AI tool.
None of this replaces SEO. A brand with strong mentions but a blocked crawler or thin product pages still loses, because the model has nothing on your site to link to. That is why the useful split is rarely SEO agency or GEO specialist. It is who owns the site and who owns everything said about you off the site, and whether anyone is measuring the result on questions buyers actually ask.
If your agency can show you a fixed prompt list and last month's results across at least ChatGPT and Google AI Mode, it is doing the work. Do not pay a second company for the same report.
Pages not indexed, a blocked crawler, slow templates or thin product pages come first. Google's page makes indexing the entry ticket. Fix that with the agency you have.
That gap is usually off-site: directories, roundups and reviews that mention them. It is outreach and entity cleanup, which many SEO teams are not set up for.
A one-time audit on a fixed prompt set gives you a baseline. You can hand it to your current agency to act on. That alone is often enough.
If it promises "AI visibility" but cannot show which questions it measures, or sells a special AI file as the main deliverable, Google's own documentation says that file is not required.
These are worked examples using our published prices, not quotes. Your SEO agency's add-on fee is its own number; put it next to these and compare like for like. Every example starts with the $495 audit, because without a baseline there is nothing to measure against.
Google requires indexing; OpenAI's search crawler must be allowed. Check robots.txt and Google Search Console first. That is free.
If buyers in your niche search by part number or buy on habit, AI answers may not drive sales yet. Run ten of your own buyer questions in ChatGPT first and see if any answer names a brand.
No one controls what a model says. A guarantee is either about a prompt so narrow nobody asks it, or it is not a real promise.
Google says no new machine-readable files, AI text files or markup are needed for its AI features. Pay for work Google and OpenAI document, not for a shortcut.
If your agency added prompt tracking or entity cleanup in the last two or three months, give it a full quarter on the same prompt list before paying anyone else. AI answers change slowly, and switching mid-stream resets your baseline.
An audit tells you what to fix. If nobody will fix it, keep the $495 and start with your own prompt list.
A real answer is a document of 30 to 100 buyer questions. No list means no measurement.
At least ChatGPT and Google AI Mode or AI Overviews; Perplexity and Gemini are common additions. Monthly is a sensible minimum.
OpenAI says a site that blocks it will not show in ChatGPT search answers. This is a two-minute check.
Google Business Profile, LinkedIn, directories, Wikidata. Ask who owns it and how often it is checked.
Roundups, review sites and industry lists. If the answer is links only, that is a gap a specialist fills.
Is it included in the retainer, an add-on, or a separate project? Put the number next to an outside quote.
Ask directly about AI-only files and special markup. Google's page says neither is required for AI Overviews.
