Google AI Features Search Content Guidance: AI Overviews Documentation

Google AI features search content guidance is not a secret playbook. It is two public Search Central documents plus a Search Console report. The AI Overviews documentation is AI features and your website. The "what should we actually do" page is Optimizing your website for generative AI features on Google Search. In June 2026 Google added generative AI performance reports.

We use those pages as the rules for Google. We do not stretch them into ChatGPT advice. For that gap we still use Promptwatch.

How Google describes AI Overviews and AI Mode

Overviews try to give the gist and a set of links. Google says they only show when they add something beyond classic results, so they often stay off. AI Mode is the longer path: comparisons, messy questions, follow-ups that used to be five searches.

Both can fan out. They issue related searches and ground the answer in extra URLs from the index. Google's lawn-weeds example fans out into herbicides, non-chemical removal, and prevention. When a client asks why a supporting link does not match the typed query, this is usually why.

Google also says visits from pages that include Overviews have been higher quality (more time on site). That is their research note. It is not a reason to chase Overviews with junk pages.

Eligibility and content guidance, without the folklore

To appear as a supporting link: indexed, eligible to show a snippet, ordinary technical requirements. Google's words: no additional technical requirements.

The AI features page then lists work we already sell as SEO:

Crawling allowed in robots.txt and at the CDN
Internal links
Page experience
Important content in text
Images and video that support the text when they earn their place
Structured data that matches what the user sees
Merchant Center and Business Profile kept current

The optimization guide is blunter on writing. Unique point of view beats a roundup of roundups. Non-commodity pages beat generic tip lists. Headings for humans. If AI helped write it, it still has to pass Search Essentials and spam policy. Do not publish a thin URL for every fan-out variant. Helpful content did not get replaced.

What Search Central says to skip

For Google Search, Google says you can ignore llms.txt and other AI-only files, chunking copy into tiny blocks, synonym-chasing rewrites, inauthentic mentions, and special Overview schema. Schema is still worth doing for rich results when it matches the page. It is not an Overview coupon.

We will not bill a client to implement a tactic those pages already dismissed. If another engine still cares about crawler files or extractable passages, that is a different ticket, measured in Promptwatch, not claimed as "Google's 2026 AI Overviews documentation."

How we measure against the documentation

GSC generative AI reports: impressions in Overviews, AI Mode, and Discover generative features; pages; countries; devices on Search; dates. Also mixed into the main Performance report (Web).

They will not show the prompt, the other citations in the module, or ChatGPT. Preview and index controls remain nosnippet, data-nosnippet, max-snippet, noindex. Googlebot robots.txt is the crawl switch. Google-Extended limits some other Google uses of content; it is not a clean "turn Overviews off, keep Search." After a control change, URL Inspection and patience; recrawl can take days to months.

Promptwatch sits beside that. Paid plans log AI Overviews and AI Mode next to ChatGPT, Gemini, Claude, and Perplexity, daily, with the cited URL and crawler hits. Essential is $95/mo. We use it when the brief is "did this question cite us," which GSC does not answer. Explore (free, ChatGPT only) is a demo.

The 2026 GEO operating note is here. Technical crawl issues still start with our audit checklist.

FAQ

Is there an official AI Overviews ranking-factor list?

No. Eligibility plus ordinary SEO plus people-first pages. Anyone selling factor 14 is guessing.

Should we add llms.txt because "AI documentation" came up?

Not for Google. Search Central says Search does not use it. We will not pretend otherwise.

Can we opt out of Overviews only?

Snippet and index controls, as documented. Blocking Googlebot drops you out of Search, including AI features. We will not promise a surgical Overview-only off switch that Google did not document.
