Search how to get mentioned in AI Overviews and the pages ranking at the top will hand you a list: add structured data, build pillar content, publish an llms.txt file, rewrite your pages for AI. Google has published guidance on this, and it contradicts most of that list directly.
The one requirement Google states
To be eligible to be shown in generative AI features on Google Search, a page must be indexed and eligible to be shown in Google Search with a snippet.
That is the whole entry requirement. There is no separate AI index to join and no second submission to make. If a page is in Google normally, it can appear in an AI answer. If it is not, nothing else on this page matters yet, and this is how to find out which one you are.
Four things Google says you do not need
- AI files. “You don’t need to create new machine readable files, AI text files, markup, or Markdown to appear in Google Search.” That includes llms.txt, which is sold hard right now.
- Chunking your content. “There’s no requirement to break your content into tiny pieces for AI to better understand it.”
- Writing specially for AI. “You don’t need to write in a specific way just for generative AI search. AI systems can understand synonyms and general meanings.”
- Schema markup for AI. “Structured data isn’t required for generative AI search, and there’s no special schema.org markup you need to add.”
Structured data is still worth having for other reasons, and I use it on this site. But it is not the lever for AI answers that agencies are currently selling it as, and the difference matters when somebody is quoting you for it.
What Google says does matter
The same guidance is blunt about what separates content worth quoting from content that gets skipped.
A first-hand review provides a unique perspective based on personal experience, whereas a summary of existing content simply restates information already available elsewhere.
That is the entire game, and it explains why so much AI-optimised content goes nowhere. If a page restates what twenty other pages already say, there is no reason for an answer to cite it rather than any of the twenty.
What that leaves you to do
- Be indexed and allowed to show a snippet. That is the floor, and it is worth confirming rather than assuming.
- Answer the question in the opening lines. Not after a paragraph of throat-clearing about how important the topic is.
- Be specific enough to quote. Real numbers, real prices, real dates, real outcomes. Vague copy gives an answer nothing to lift.
- Publish something only you could write. What you charged, what went wrong, what you measured, what you would do differently. Nobody else can restate that.
- Be mentioned off your own site, because an answer assembled from many sources weighs the ones you do not control most heavily.
AI Overviews and ChatGPT are not the same job
These get talked about as one thing. They are not. An AI Overview sits on a Google results page and is built on Google’s own index, so being indexed and useful is the whole path in. ChatGPT is a separate system with its own sources, and being strong in Google does not automatically carry over: how to get your business on ChatGPT.
Your buyer uses both without thinking about the difference, which is why it is worth covering both rather than picking.
The honest summary
There is no AI Overviews switch. The requirement is ordinary good search health, and the differentiator is having something first-hand to say. Most of what is sold as AI optimisation is the first part repackaged at a premium, with a file or a markup format bolted on to make it look new.
