Google AI Overviews Optimization Tool
Google AI Overviews optimization starts with eligibility: Google says a page must be indexed and eligible for a snippet, and there is no separate way in. 99Visibility reads the AI Overview Google shows for your keywords, records which sites it links, and checks the controls that can quietly keep your pages out.

How Google AI Overviews works for AI visibility
Built on Google Search
AI Overviews are written from Google Search's own index, by a Gemini 3 family model whose exact version Google does not publish. Google states that to be shown as a supporting link, "a page must be indexed and eligible to be shown in Google Search with a snippet," and that "There are no additional technical requirements."
Eligible is not included
The same Google page says "Indexing and serving isn't guaranteed." Many queries show no overview at all, and Google says AI Overviews and AI Mode "may use different models and techniques," so their links can differ.
One crawler, no AI-only switch
Pages drop out of Google Search. AI Overviews and AI Mode are built into Search and use the same crawler — Google states there is no separate robots.txt token for them.
Controls that take you out
noindex removes a page from the index; nosnippet, max-snippet:0 and data-nosnippet remove text from snippets, and with it from AI features. They are often inherited from a template. Search Console also has a generative AI setting, on by default where Google has rolled it out, that a child property inherits from its parent.
How it cites
An overview shows supporting links next to the generated text. Search Console's generative AI report counts impressions only, with no clicks and no position.

Googlebot (Google Search, AI Overviews, AI Mode)
Pages drop out of Google Search. AI Overviews and AI Mode are built into Search and use the same crawler — Google states there is no separate robots.txt token for them.

Your content is excluded from training future Gemini models and from Vertex AI grounding. Google states it does not impact inclusion in Google Search nor is it used as a ranking signal.

What is not documented
- How Google picks the supporting links. Google publishes no AI Overviews ranking factors and states there are no special optimizations for them.
- How much organic rank matters. About 38% of cited URLs ranked in the top 10 in one large study (Ahrefs, March 2026) and 16.7% in another (BrightEdge, September 2025); the two methods disagree.
- Which queries trigger an overview. Google does not say, and we read the results of one market: yours.
- Whether your property has been opted out in Search Console. That setting cannot be seen from outside, so the audit cannot check it; you can.

Reads the overview Google shows
For each keyword, typed as a person would search it, we read the overview on the Google results page in your market: its text and the sites it links. When Google shows none, the keyword is skipped on this column, not scored as a miss. It is on every plan, Free included.
Checks Googlebot and your snippet controls
The access check reads robots.txt for Googlebot and the Google-Extended token, requests your page as Googlebot, and scans it for noindex, nosnippet, max-snippet:0 and data-nosnippet. A robots.txt block on Googlebot is ranked critical; a stray snippet control is flagged with where it was found.
Flags wrong facts
Every Google AI Overviews answer is read against the price, founding year, location and features in your brand profile. On Free you see how many answers contradict them; what each flag says, with a severity of critical, moderate or minor, starts on Starter ($49/mo).
Counts the links, beside your rank
The sites an overview links are stored with it, and the citation rate counts the share that are yours. On Starter ($49/mo) and up, the audit also records your classic Google position for the same keyword, so you can see whether ranking and being linked line up.
A platform note in the fix list
When the Google AI Overviews column scores more than 20 points under your overall score, the fix list adds a note for it. It tells you to check that the page is reachable by Googlebot, readable without JavaScript and free of snippet controls, then to look at what Google AI Overviews cited instead.
Agent V for Google AI Overviews
Agent V is the assistant in your dashboard, on every plan. It reads your audits, your accuracy flags and pages on your own site, so you can ask what an engine said for a prompt and which fix applies.
Ask it to read a page on your site and V returns its headings, robots directives and visible text, so a stray noindex is easy to spot. Its robots.txt draft covers the AI-specific crawlers, not Googlebot.
V can also check a page on your site or run a new audit. Each change it proposes shows up as a "V wants to" card and does nothing until you confirm, and V never edits your site: drafts are text you paste yourself.
Google AI Overviews optimization: what to fix first
Check every page you want linked for noindex, nosnippet and max-snippet:0, in the HTML and in the X-Robots-Tag header. Any one of them takes the page out.
Keep data-nosnippet on boilerplate only. Text marked with it stays indexed but is left out of snippets and AI summaries (Bing), and Google treats it as a snippet control too.
Leave Googlebot allowed in robots.txt. There is no robots.txt token that blocks AI Overviews alone; blocking Googlebot takes the page out of Google Search.
Check the generative AI setting in Search Console, on the property and on its parent. Inclusion is the default, but an opt-out on a parent property is inherited.
Skip schema as an AI Overviews tactic. Google says no special schema.org markup is needed, and in Ahrefs' matched test, already-cited pages that added schema saw 4.6% fewer AI Overview citations.
