Why does Copilot cite my site when Google's AI features don't?

An AI engine can only cite a page that sits in the index it retrieves from. Copilot and Google's AI features retrieve from different indexes, so they can reach opposite verdicts on the same site.

Microsoft Copilot grounds its answers in Bing's index. If Bingbot has crawled and indexed your page, Copilot has a candidate it can pull into an answer. You can read more on how Copilot grounds answers in Bing.

Google's AI Overviews and AI Mode work from Google's index. Google's documentation states that a page "must be indexed and eligible to be shown in Google Search with a snippet" to appear as a supporting link, and that "there are no additional technical requirements." That is a gate, not a boost. If Google hasn't indexed the page, or can't show a snippet for it, Google's AI features have nothing to cite.

So the usual explanation is simple. Bing holds your page and Google doesn't, or Google holds it but something blocks the snippet. For a side-by-side view of which answers use which index, see Bing index vs Google index for AI answers.

Each of these can keep you out of Google's AI answers while Copilot keeps citing you. All of them are things to check, not things to assume.

• Not indexed. The page never made it into Google's index, or Google removed it. Google's spam policies define scaled content abuse as "when many pages are generated for the primary purpose of manipulating search rankings and not helping users," and removal under that policy can arrive with no notice.
• No snippet allowed. noindex, nosnippet, max-snippet:0 and data-nosnippet are Google's documented controls for keeping content out of AI answers. Templates often carry them by accident. Bing supports data-nosnippet too, so check which engine each tag affects.
• Googlebot blocked. There is no separate robots.txt token for AI Overviews or AI Mode. Googlebot rules are the control, so blocking Googlebot removes you from both Search and its AI features.
• Opted out in Search Console. As of October 2026, Google is rolling out a Search Console control for AI Overviews, AI Mode and Discover generative AI features. Inclusion is the default, but child properties can inherit an opt-out from a parent property. Nobody outside your account can see it.
• No AI answer for the query. AI Overviews often don't trigger at all. A query where Copilot answers may simply show no Overview on Google.

OtterlyAI, which sells AI visibility tracking, ran a public test in 2026 and published the numbers. It is one example, not proof of a general rule. Our write-up of the Otterly 2,000 AI blogs experiment covers the method in full.

Otterly loaded two new domains with roughly 1,000 AI-generated posts each. Google removed one after about 14 days and the other after about 90, with zero manual actions reported in Search Console. Bing never deindexed either site.

The citation split followed the index split. Otterly tracked 3,934 AI citations for one site, and 2,718 of them (69%) came from Microsoft Copilot. Google AI Overviews, AI Mode and Gemini almost never cited the sites. Microsoft's own AI Performance report credited that site with 42,817 citations, far more than the prompt-based tracker logged, though the time windows may not match.

The limits matter. There was one site per arm, no human-written control, and a low-stakes informational topic. Do not read it as a recipe. Read it as a clean illustration that an engine cannot cite what its index no longer holds.

Being in an index makes you eligible. It does not make you cited. In Otterly's test, ChatGPT's crawlers kept visiting the sites and ranking in Bing still produced effectively zero ChatGPT citations. "ChatGPT uses Bing" is not a strategy. If a similar split puzzles you on other engines, see why Perplexity cites you but ChatGPT doesn't.

The reverse case is common too. Google can index you and still cite other pages, because retrieval and citation are decided per query by the engine. Nobody outside Google controls that step.

Finally, your own counts are samples. A prompt tracker only sees answers to the prompts it asks. Where an engine publishes its own count, as Bing does, that count sees more.

Work through the gates in order, one engine at a time. The index status playbook has the detailed steps.

1. Google Search Console. Use URL Inspection on the pages Copilot cites. Confirm they are indexed and that no noindex or snippet restriction applies. Check whether the property, or its parent, has opted out of AI features where that control is visible.
2. Bing Webmaster Tools. Confirm index status there separately. Then open the AI Performance report, which shows Copilot citations and the grounding queries the AI actually ran. Our guide to reading Bing's AI Performance report explains each metric.
3. Your HTML and headers. Search templates for data-nosnippet, nosnippet and max-snippet tags that hide content you want shown.
4. If Google removed you. Read the spam policies honestly. Volume without value is the pattern Google describes. Fix the content, not the markup.

What you control is eligibility in each index. What you don't control is whether a given answer uses you.
