AI Overviews are the generated summaries Google shows above some search results, with links to the pages it drew on. Many site owners want to know how to get into those links. The useful answer is shorter than most of the advice written about it.
Google has published guidance on this, in its Search Central documentation on AI features. This article sticks to what that guidance says, and marks clearly where anything goes beyond it.
What Google has said
The core points from Google's own documentation:
- There are no additional requirements. To be eligible as a supporting link in AI Overviews or AI Mode, a page must be indexed and eligible to be shown in Google Search with a snippet. Nothing else is required.
- No special optimisation is needed. Google says the same SEO practices that apply to search in general apply here. There is no AI-specific markup, file or schema type.
- The same controls apply. If you limit snippets for a page, that limit applies to AI features too.
- Links can go beyond the top results. Google describes a "query fan-out" technique, where the system runs several related searches across subtopics to build the answer. That means a page can be linked for part of a question even if it does not rank first for the whole query.
That is the official picture. A page that Google has indexed, and is allowed to quote, is in the pool. Which pages get chosen from the pool is decided by Google's systems, and Google has not published a formula.
Step one: be indexed
Most pages that never appear in AI Overviews are missing for an ordinary reason: they are not in Google's index, or they are not the version Google chose to index.
Check the page in Search Console with the URL Inspection tool. It should say the URL is on Google. If it is not, the usual causes are:
- A
noindextag or header left on from a staging site or a plugin setting. - A robots.txt rule blocking Googlebot from the page or from the resources it needs to render.
- A canonical tag pointing at a different URL, so Google indexes that one instead. See canonical tags and duplicate content.
- The page is "Crawled, currently not indexed" because Google did not think it was worth indexing.
Why Google is not indexing your page goes through each status and what to do about it.
Step two: be eligible for a snippet
A page can be indexed and still not be quotable. These controls decide what Google may show from a page, and AI Overviews respect them:
<!-- No snippet at all, in normal results or AI features -->
<meta name="robots" content="nosnippet">
<!-- Snippets limited to 50 characters -->
<meta name="robots" content="max-snippet:50">
<!-- Keep one part of the page out of snippets -->
<div data-nosnippet>Members-only pricing table</div>
The same rules can be sent as an X-Robots-Tag HTTP header, which is useful for PDFs.
These are worth checking even if you never set them on purpose. Some themes and SEO plugins add max-snippet or nosnippet options, and a site-wide setting chosen years ago for another reason quietly applies to AI Overviews now.
The trade-off is simple. Restricting snippets reduces how much of your text Google can show, in AI Overviews and in normal results. It does not get you a link without the quote. If you want to appear, let Google show a snippet.
What about Google-Extended?
Google-Extended is a robots.txt token that controls whether your content is used to train and ground Gemini models and some other Google AI products. It does not affect Google Search, and Google states that it does not affect inclusion in AI Overviews.
So blocking Google-Extended is a decision about training, not about visibility in search. Should you block AI crawlers? covers that decision for Google and the other AI companies.
What probably helps, and why it is not official
Beyond eligibility, Google has not published what makes one page more likely to be linked than another. What follows is reasoning from how the feature works, not a rule from Google.
Pages that already do well in search. AI Overviews draw on Google's index and ranking systems. A page that ranks for related queries is in a stronger position than one that does not. There is no shortcut that bypasses normal SEO.
Answers stated plainly on the page. If the overview needs a sentence that says "a passport renewal takes six weeks", a page that contains that sentence is easier to use than one where the answer is implied across a long introduction. Writing pages that answer the search covers how to structure that.
Coverage of the sub-questions. Because of query fan-out, a page that clearly answers one specific part of a broader question may be linked for that part. A focused section with a heading that names the sub-question gives it a clean target.
Text that is in the page. Google renders JavaScript, but text that only appears after a click, inside an image, or behind a login is harder or impossible to use.
Treat these as good practice that also helps your normal results, which is the point. Nothing here is AI-specific.
What does not help
- Structured data added for AI Overviews. Structured data is useful for rich results and helps Google understand pages, but Google says no special markup is needed for AI features. Adding schema will not by itself earn a link.
- llms.txt. Google has said its search systems do not use it. What llms.txt is covers where it does have a use.
- Rewriting every page as a list of questions. Pages written for people still need to work for people. A page that reads like a keyword list is no more useful to an overview than it is to a reader.
Measuring it
Search Console includes AI Overview and AI Mode clicks and impressions in the Performance report, under the Web search type. They are not separated from ordinary results, so you cannot filter to AI Overviews alone.
What you can do:
- List the questions your customers search for and check the results by hand. Note which pages are linked in the overview and whether yours is one.
- Watch the queries and pages in Search Console over time. A change in impressions on question-style queries is a hint, not proof.
- Keep the mechanics right. Rankwell's readiness check confirms that Googlebot is allowed by robots.txt and that the homepage is not set to
noindex. Snippet settings you still check by hand, in your page source or SEO plugin.
The short version
Be indexed, allow snippets, and answer the question clearly on a page that already deserves to rank. That is what Google has said, and almost everything else is speculation. If someone sells you a special AI Overviews optimisation, ask them to point to the line in Google's documentation that supports it.
