Google AI Mode Visibility Checklist

Google's AI features page sets the bar plainly. To be shown 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." The same page says there are "no additional technical requirements" and no "special optimizations necessary." Eligibility is not inclusion, though. Google also states that indexing and serving isn't guaranteed.

What to check:

• The pages you care about (pricing, product, about) are indexed. Use URL Inspection in Search Console.
• Your robots.txt does not disallow Googlebot on those paths. As of October 2026, there is no robots.txt token that blocks AI Mode on its own. Googlebot rules govern every Google Search surface at once.
• You haven't confused Google-Extended with a Search control. Google says it "does not impact a site's inclusion in Google Search." It governs training and grounding for Gemini Apps and Vertex, which our Gemini optimization checklist covers separately.

Index status is the gate that matters most. In Otterly's 2026 experiment, Google deindexed two AI-generated sites and Google's AI surfaces almost stopped citing them, while Bing-grounded Copilot kept going. For the full reading of Google's wording, see Google's AI features documentation, digested.

Google documents noindex, nosnippet, max-snippet and data-nosnippet as the on-page controls that limit how content appears in its AI features. They are suppression tools only. No markup makes a section more likely to be used. The real risk is applying them by accident, often through a template someone edited to hide a cookie banner or a legal footer.

The patterns to search your HTML and headers for:

<meta name="robots" content="nosnippet">
<meta name="robots" content="max-snippet:0">
<div data-nosnippet>...</div>

Also check the X-Robots-Tag HTTP header, which can carry the same directives without appearing in the page source. For each hit, confirm someone chose it on purpose. If a data-nosnippet wrapper sits around your pricing table, AI Mode can't quote that table as a snippet, even if the page ranks.

Googlebot renders JavaScript, so client-side rendering is not the blocker here that it is for most other AI crawlers. Googlebot does stop at 2MB per URL, but Google says the vast majority of sites never hit that limit. Flag it only when a page actually exceeds it.

Search Console has a control for Google's generative AI features. It covers AI Overviews, AI Mode and generative AI features in Google Discover. Three details matter.

1. It is opt-out, not opt-in. Inclusion is the default for all properties. You don't need to switch anything on to be eligible.
2. Child properties inherit. The default for a child property is "Inherit control from parent." A domain property opted out by one team can silently remove a subfolder another team owns.
3. Not everyone can see it yet. As of October 2026, Google describes the control as rolling out to a subset of owners. If your property shows no toggle, record that and recheck each quarter.

Google says the control isn't used as a ranking or inclusion signal for other parts of Search. Opting out of display also doesn't stop Google from using content to improve Search in general.

Nobody can see this setting from outside. It needs someone with Search Console access and one screenshot per property. If it's set to opt out, nothing else on this list will make a difference, so check it before anything else.

Google doesn't document brand-fact consistency as an AI Mode factor. It's hygiene. The reasoning is simple: when your own pages state a fact two different ways, any engine that reads them can repeat either version.

List the facts buyers ask about and check that each one is stated once, the same way, everywhere:

• Prices and plan names
• Product and feature names, including retired ones
• Founding year, headquarters and ownership
• Integrations and certifications

Compare the pricing page, about page, footer, help docs and any structured data block. Put each key fact in plain text in the HTML, in one clear sentence. A specific, fetchable statement such as a price or a one-line definition gives an engine a sentence it can quote. That's the only on-page content pattern with a positive experimental signal in our evidence base. It still guarantees nothing about what AI Mode will say.

Google says AI Overviews and AI Mode "may use different models and techniques" and can return different links. As of October 2026, Google's I/O post says AI Mode has defaulted to gemini-3.5-flash since May 2026, while Google publishes only "Gemini 3" for AI Overviews. Treat them as two products and log them in two columns.

A workable plan:

1. Pick a fixed set of buyer questions, around 10 to 30, written the way customers actually ask.
2. Run each one in AI Mode logged out, and record whether your brand is named, which URLs are linked, and any wrong facts.
3. Run the same queries for AI Overviews separately. An Overview often won't trigger at all.
4. Date every capture and repeat on a fixed schedule, such as the quarterly AI visibility review.

Know the limits. Google may use "query fan-out," issuing multiple related searches behind one prompt. Your test prompts are a proxy for inputs you can't see. Search Console's generative AI report shows impressions only, with no clicks, CTR or position. Google also confirmed a bug that depressed impressions from around 12 August 2026, so read trends from that window with care. Our page on whether you can track what Google AI Mode says about your brand goes deeper. For a quick look at a single query, the Google AI Mode Checker on 99Visibility shows what AI Mode returns.

Google's generative AI optimization guide says you don't need new machine-readable files, AI text files, markup or Markdown to appear in its generative features. It also says you don't need to write in a special way for AI, and that there's no ideal page length. So:

• Schema isn't required for generative AI search. Ahrefs' matched test found no major citation uplift on any platform. In that test, AI Mode moved +2.4% and AI Overviews fell 4.6%. Existing markup does no harm, but it isn't a lever.
• llms.txt: Google Search ignores it.
• Chunking or "AI-friendly" rewrites: Google rejects both.
• AI Mode rank tracking: no position data exists to check such a number against.

What stays out of your control: whether AI Mode runs a search for a given prompt, which retrieved pages it cites, and how it words the answer. For the reasoning behind link selection, read AI Mode SEO.
