How a small business shows up in Google’s AI Overviews (it is less mysterious than it sounds)

4.1What Google says, in its own words

The core paragraph would fit on a sticky note.

Quoted

“The best practices for SEO remain relevant for AI features in Google Search (such as AI Overviews and AI Mode).”

Quoted

“There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary.”

The page then rules out the shortcuts people are selling:

Quoted

“You don’t need to create new machine readable files, AI text files, or markup to appear in these features.”

Quoted

“There’s also no special schema.org structured data that you need to add.”

The one technical condition is the ordinary one: “a page must be indexed and eligible to be shown in Google Search with a snippet.” Google repeats: “There are no additional technical requirements.”

So the honest answer to “how do I get into AI Overviews?” is: the same way you get into Google at all. Be indexed, be eligible for a snippet, and be the most useful answer to the question being asked.

4.2What that means for the “AI text file”

You may have been told to add an llms.txt file. It is worth knowing what that is. The project’s own site describes it as “a proposal to standardise on using an /llms.txt file to provide information to help agents use a website.” It is a proposal, published by an individual, not a Google requirement.

Adding one is harmless. But Google’s documentation for its AI features says, in as many words, that you do not need new “AI text files” to appear in them. If someone is selling you one as the key to Google’s AI answers, that claim is not supported by Google’s own page.

4.3What about blocking Google’s AI?

Some owners want the opposite: to keep their content out of AI features. Here the details matter, because there are two separate controls.

Snippet controls affect AI features in Search. Google’s page says: “To limit the information shown from your pages in Search, use nosnippet, data-nosnippet, max-snippet, or noindex controls.” These are the same controls that limit ordinary search snippets. Use them and you limit both.

Google-Extended is a different thing. Google’s crawler documentation describes it as a token publishers can use to manage whether their content may be used “for training future generations of Gemini models that power Gemini Apps and Vertex AI API for Gemini,” and for grounding in those products. And crucially: “Google-Extended does not impact a site’s inclusion in Google Search nor is it used as a ranking signal in Google Search.”

In other words, blocking Google-Extended in robots.txt is a decision about Gemini, not about AI Overviews in Search. Owners mix these up in both directions.

4.4Measuring it

You do not need a new tool to see whether AI features send you visitors. Google says traffic from them is “included in the overall search traffic in Search Console,” reported “in the Performance report, within the ‘Web’ search type.” If you are not in Search Console yet, that is the first thing to set up, and it is free.

4.5Where I would spend the time instead

If the requirements are just good SEO, the question becomes what “good” means for a small business in a world where an AI is summarizing the results. My view, as someone who builds websites for a living:

Answer the question someone actually asks. People ask AI features full questions: “Is there a bakery near Queen and Broadview that does gluten-free birthday cakes?” A page that clearly says what you make, where you are, and who it is for is far easier to cite than a homepage that says “Welcome to our world of flavour.”

Put facts in text, not only in images. Opening hours inside a designed graphic, a menu as a photo, prices only in a PDF: these are hard for any system to read. Write them on the page.

Make structured data match the page. Structured data is not required for AI features, but if you use it, Google’s general rule applies: “Your structured data must be a true representation of the page content,” and “Don’t mark up content that is not visible to readers of the page.” Markup that disagrees with your page is worse than none.

Keep one source of truth. If your hours on the website, on your Google Business Profile and on a delivery app all differ, any summary of you will be confused. Pick one place to update first and copy from it.

Be the original. A page that repeats what ten other pages say gives a summary no reason to point to you. Your own photos, your own prices, your own process, your own answer to the question customers always ask: those are things only you can publish.

4.6The short version

• There is no special file, markup or schema for AI Overviews. Google says so.
• The requirement is to be indexed and eligible for a snippet.
• Snippet controls limit AI features in Search; Google-Extended governs Gemini and does not affect Search.
• Measure it in Search Console’s Performance report.
• Spend the effort on clear, original, factual pages.

It is less mysterious than the sales pitches suggest, and a lot more within a small business’s control. I’m Sal Talash, and I write about websites, AI and running a business online at saltalash.vercel.app.
