Featured snippet: definition and the AI link

A featured snippet is a block of text Google extracts from one page and shows as a direct answer on the results page. It usually sits at or near the top, with a link to the source page. People also call it an answer box.

It differs from a standard snippet, which is the short description under every blue link. A featured snippet is a larger, highlighted extract chosen to answer the query outright.

It also differs from rich results, which are enhanced listings driven by structured data. A featured snippet is a passage of your page's own text.

Google can only show a snippet of a page it has indexed and is allowed to excerpt. Two conditions apply:

• The page is in the index. A noindex directive removes it, and with it every snippet. See index eligibility for the first gate.
• The page permits snippets. Google documents on-page controls that limit or block excerpting.

The controls, per Google's robots meta tag specification:

• nosnippet blocks any text snippet for the page.
• max-snippet caps snippet length in characters. max-snippet:0 acts like nosnippet.
• data-nosnippet is an HTML attribute that excludes a specific section from snippets.

A page-level example:

<meta name="robots" content="max-snippet:160">

Bing added data-nosnippet support on October 15, 2025. Bing says marked content "is still indexed normally, but it will be excluded from snippets and AI summaries," and remains available for ranking.

The next move: check your templates for these directives. They are often inherited from a theme or added to hide one element, then applied site-wide by accident.

Google ties its AI features directly to snippet eligibility. Its AI features documentation states that 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." It adds: "There are no additional technical requirements."

That has two consequences.

1. Snippet controls are AI controls. Google names nosnippet, data-nosnippet, max-snippet and noindex as the ways to limit how content appears in AI features. A page set to nosnippet cannot be a supporting link. A section wrapped in data-nosnippet will not be quoted.
2. There is no separate AI path into Google. Google says no special optimizations are needed to appear in AI Overviews or AI Mode. The access work you do for classic search is the access work for its AI surfaces.

What you control: indexing and snippet permissions. What you do not control: whether Google chooses your page for a given query. Google's own page says indexing and serving "isn't guaranteed." For a full walkthrough of the directives, read the guide on nosnippet and data-nosnippet in AI answers.

"A featured snippet means an AI Overview citation"

No. They are separate features with separate selection. Ahrefs found that 37.9% of URLs cited in AI Overviews also appeared in the first 10 result blocks (March 2026), so many citations come from pages outside the top results. The featured snippets vs AI Overviews comparison covers the differences.

"Markup or special formatting wins the answer box for AI"

Google's AI optimization guide says you don't need to write in a specific way for generative AI search, and that new markup or AI text files are not needed. Snippet eligibility is a permission, not a formatting trick.

"Blocking snippets is harmless for AI"

It is the opposite. Snippet controls are the documented way to suppress AI display. Use them when you mean to, and know what each one removes. The noindex vs nosnippet vs data-nosnippet comparison shows which control does what.

"robots.txt can block AI Overviews alone"

As of October 2026, no robots.txt token blocks AI Overviews or AI Mode separately from Search. Googlebot rules and on-page snippet controls are the levers.

• Index eligibility: the first gate before any snippet can appear.
• nosnippet and max-snippet: the page-level snippet controls.
• Rich results: structured-data listings, distinct from extracted answers.
• Supporting link: a cited source shown inside an AI Overview or AI Mode answer.
• AI Overview: Google's generated summary at the top of some results, which draws on snippet-eligible pages.

Is a featured snippet the same as an answer box? In everyday use, yes. Both names describe the highlighted extract Google shows to answer a query directly, with a link to the source page. It is different from the standard snippet under each result and from rich results, which depend on structured data rather than a lifted passage of text.

Does nosnippet remove my page from AI Overviews? It removes the page as a possible supporting link. Google requires a page to be eligible to show with a snippet to appear as a supporting link in AI Overviews or AI Mode, and nosnippet blocks snippets. The page can stay indexed and still rank in classic results, but it cannot be excerpted.

Can I hide part of a page from AI answers but keep the rest? Yes. The data-nosnippet attribute excludes a marked section from snippets. Google documents it, and Bing says content marked this way is still indexed and available for ranking but excluded from snippets and AI summaries. It is the only documented control that works below the page level.

If I lose a featured snippet, will I lose AI citations too? Not necessarily. Losing the featured snippet position is a selection outcome, not an eligibility change. AI features choose sources separately. Check whether anything changed your eligibility, such as a new noindex, nosnippet or max-snippet directive. If those are clean, the page is still eligible for both.
