Key takeaways
- To be a supporting link, a page must be indexed and eligible to show in Google Search with a snippet. Google lists no extra technical requirement.[1]
- Both features may use query fan-out: many related searches run at once, which widens the set of pages that can be linked.[1][2]
- Google says you don't need llms.txt, special schema or content chunking for its AI features.[2]

What's the difference between AI Overviews and AI Mode?
AI Overviews are short AI summaries that appear on some normal search results pages. AI Mode is a separate, conversational search experience built for longer questions, comparisons and follow-ups. Google says the two may use different models and techniques, so the answers and links they show will differ, and that AI Overviews only appear when its systems judge them additive, so they often don't trigger.[1]
| AI Overviews | AI Mode | |
|---|---|---|
| Where it shows | Above or within classic results, on some queries only | A dedicated mode for exploratory questions |
| Built for | Getting the gist of a topic quickly[1] | Reasoning, nuanced questions and complex comparisons[1] |
| How links are found | Google's index, with possible query fan-out[1] | Google's index, with possible query fan-out[1] |
| What it means for you | Track how often it appears for your queries, and whether you are linked | Track which pages are cited across longer, multi-part questions |
Because the outputs differ, measure them separately. Being linked in an AI Overview for a query does not mean you are cited in AI Mode for the same question. The engine pages for AI Overviews and AI Mode cover how each is tracked.
How does Google choose which pages to link?
Google picks links from its normal search index using its core ranking systems. Its optimization guide describes two techniques: retrieval-augmented generation, where ranking systems retrieve relevant, current pages that the answer is grounded in, and query fan-out, where the model issues several related queries at once.[2] Google's example is a question about fixing a weedy lawn that fans out into searches about herbicides, chemical-free removal and prevention.[2]
The practical effect: a page can be linked for a question it never targeted directly, because it ranked for one of the sub-queries. A plumbing company in Chicago might be cited for "how to fix a running toilet" through a fan-out query about replacing a flapper valve. Covering the real sub-questions of a topic matters more than matching one exact phrase.
Eligibility checklist: can your pages appear at all?
A page can only be linked if it is indexed and allowed to show a snippet.[1] Google adds that meeting every requirement still doesn't guarantee crawling, indexing or serving.[1] Start with these checks:
Googlebotis allowed in robots.txt, and your CDN or host does not block it. Google names both places explicitly.[1]- Important pages return a 200 status, are not
noindex, and show as indexed in Search Console's URL Inspection tool. - No
nosnippetormax-snippet:0on pages you want cited. Those directives also block or limit use as a direct input to AI Overviews and AI Mode.[4] - Key content is in text, not only in images, and internal links make every important page reachable.[1]
- Structured data matches what is visible on the page.[1]
- Merchant Center feeds and your Business Profile are current, if you sell products or serve a local area.[1][2]
The free AI crawler checker reads your robots.txt and response headers for Googlebot and other AI-related bots, so you can rule out accidental blocks in one step.
What content gets linked?
Google's answer is non-commodity content: pages with a perspective or information that isn't already everywhere. It contrasts generic advice lists with first-hand accounts and expert takes that go beyond common knowledge, and says unique, useful content is likely to matter more over time than any other suggestion in its guide.[2]
- First-hand evidence. Tests, measurements, photos, prices you actually charge, outcomes you actually saw. A Toronto accounting firm explaining a real filing deadline problem it solved beats a generic "tax tips" post.
- Clear structure. Sections with descriptive headings help readers, and Google says it can find the relevant part of a long, multi-topic page on its own.[2]
- Images and video. AI features can pull in relevant images and video, which creates more ways to appear than a text link.[2]
- Product and local data. For shops and local services, Merchant Center feeds and Business Profiles help listings and business details show in AI responses.[2]
- Real reputation. Google notes its AI features can reflect what is said about products and services across blogs, videos and forums, but that chasing inauthentic mentions isn't as helpful as it might seem.[2]
See whether an AI Overview appears for your questions, which sites it links, and whether you are one of them.
Check your AI Overview visibilityWhat you don't need to do
Google's optimization guide includes a mythbusting section. These are the claims it says you can ignore for Google Search:[2]
| Common advice | What Google says |
|---|---|
| Add an llms.txt or other AI-specific file | Google Search doesn't use them. They neither help nor harm your Search visibility, though other services may use them |
| Chop content into tiny chunks | Not required. Google can understand multi-topic pages and show the relevant part |
| Rewrite everything for AI | Not needed. AI systems understand synonyms and meaning without exact phrasing |
| Add special AI schema | There is no special schema.org markup for AI features. Structured data still helps rich results |
| Buy or plant mentions | Inauthentic mentions aren't as helpful as they seem, and spam systems still apply |
Google also says no third-party tool has access to its internal ranking or AI systems.[2] That applies to every tracker, including this one: what a tracker can do is sample the public results people actually see, report how often you appear, and say how certain that number is. The llms.txt guide covers where llms.txt may still be worth having.
How to control what Google's AI features use
Use the same preview controls as classic Search. Google says robots.txt rules for Googlebot are the access control for Search, and that nosnippet, data-nosnippet, max-snippet and noindex limit what is shown, including in AI features.[1]
| Control | Effect on AI Overviews and AI Mode |
|---|---|
nosnippet (meta robots) | No snippet anywhere in Search, and the content is not used as a direct input to AI Overviews or AI Mode[4] |
max-snippet:[number] | Caps the snippet length and limits how much content can be used as direct input[4] |
data-nosnippet (HTML attribute) | Excludes the marked part of a page from snippets. Works on span, div and section elements[4] |
noindex | Removes the page from Search, and so from AI features[1] |
Google-Extended (robots.txt token) | Controls use for Gemini model training and grounding in some other Google systems. It does not affect inclusion or ranking in Google Search[5] |
<!-- Keep this page out of AI answers and snippets -->
<meta name="robots" content="nosnippet">
<!-- Or exclude one block only -->
<div data-nosnippet>Members-only pricing details</div>Changes are not instant. Google says recrawling can take from several days to several months, and suggests using URL Inspection to confirm Googlebot sees the directive.[1] The AI crawlers and robots.txt guide explains the other engines' controls.
How to measure AI Overviews and AI Mode
Use Search Console for impressions, and sample the results yourself to see who else is linked. Google says appearances in AI features are counted in the overall Performance report, under the Web search type.[1] Since June 2026, Search Console also has dedicated generative AI performance reports, which Google says rolled out to all websites worldwide by August 31, 2026.[3]
- Impressions: how often your URLs appeared in generative AI features in Search and Discover.[3]
- Pages: which URLs appeared.[3]
- Countries and devices: where and on what your pages were seen (devices for Search only).[3]
- Dates: hourly to monthly granularity.[3]
What Search Console won't show you is the answer itself: which competitors were linked, what the summary said about you, or how often an AI Overview appeared for queries where you never earned an impression. That is where sampling helps. Glossy Data asks the same questions on AI Overviews and AI Mode in each market you choose and reports how often you are named, with a sample size and a 90% range on every number. Paid plans add a Source Map of the sites the engines cite. The methodology explains how.
A 30-day plan
- Week 1: list 20 to 40 non-branded questions per market. Check crawl access, indexing and snippet directives on your key pages.
- Week 2: baseline. Record how often an AI Overview appears for each question, which domains are linked, and your Search Console AI impressions by page and country.
- Week 3: improve the pages closest to being cited. Add first-hand detail, answer the obvious sub-questions, add useful images, and fix structured data mismatches.
- Week 4: update Merchant Center and Business Profile details, then re-measure. Compare ranges, not single results, and keep going monthly.
Frequently asked questions
Google says no. There are no additional requirements beyond being indexed and eligible for a snippet, and standard SEO best practices apply to both AI Overviews and AI Mode.
No. Google says Google-Extended does not affect inclusion or ranking in Google Search. To limit AI Overviews and AI Mode, use nosnippet, max-snippet, data-nosnippet or noindex.
Yes. AI features are counted in the Performance report under the Web search type, and the generative AI performance reports show impressions by page, country, device and date.
It isn't required and there is no special AI markup. Google still recommends structured data for rich results, and it should match the visible page content.
Google says the two features may use different models and techniques, so the responses and links they show vary. Measure and improve for each separately.
