What Is a Featured Snippet? Understanding Position Zero in the AI Search Era
A featured snippet is an excerpt from a web page that Google shows in a highlighted box for some queries, set apart from the regular list of results, which is why SEOs call it “position zero.” Google picks the page and the passage itself; you cannot apply for one. What has changed in the AI search era is the space around it: an AI Overview can now appear on the same results page, and it works differently from a snippet even though both answer a question directly.
How a Featured Snippet Is Chosen
Google’s documentation on featured snippets answers the basic question plainly. Asked “How can I mark my page as a featured snippet?”, it replies: “You can’t. Google systems determine whether a page would make a good featured snippet for a user’s search request, and if so, elevates it.”
Three details from the same page are useful in practice:
- Featured snippets “can also appear within a related questions group (also known as ‘People Also Ask’).”
- “Clicking a featured snippet takes the user directly to the section of the page that appeared in the featured snippet,” and that scrolling “happens automatically, without any additional annotation by the site.”
- Google adds that featured snippets “will only appear if enough text can be shown to generate a useful featured snippet.”
Google’s Search Help also has a consumer-facing explanation of how featured snippets work.
Opting Out
Some publishers prefer that a short answer not be shown in a box, for example when the full value of the page is in the detail. The featured snippets documentation describes the controls:
- The
nosnippetrule blocks all snippets for a page, featured and regular. - Text marked with the
data-nosnippetattribute will not appear in featured snippets or regular snippets. - To keep regular snippets but avoid featured ones, Google suggests experimenting with lower
max-snippetvalues, while noting that “Google does not provide an exact minimum length required to appear as a featured snippet” and that a low setting “doesn’t guarantee that Google will stop showing featured snippets for your page.”
Featured Snippets and AI Overviews
The two are separate features. A featured snippet is an excerpt from one page. An AI Overview is a generated response; Google’s Search Help on AI Overviews describes it and its links to supporting websites, and Google’s site-owner documentation on AI features explains that AI Overviews and AI Mode “may use a ‘query fan-out’ technique,” issuing related searches across subtopics to build a response.
For a site owner, the difference shows up in three ways:
- Visibility: a page can be linked from an AI Overview without holding a featured snippet, and the reverse.
- Competition for attention: when both appear, the snippet is not the only direct answer on the page.
- Effort: Google sets no extra requirements or special optimizations for AI Overviews or AI Mode. The same clear, well-organized page serves both.
Writing Pages That Can Be Excerpted
Because Google selects snippets on its own, the useful work is making a clear answer easy to lift:
- Put a direct answer right after the heading that asks the question, then add the detail.
- Make the answer stand on its own, since it will be read out of context.
- Shape the answer the way the question implies. The pairings below are editorial guidance, not Google rules.
| Question pattern | A format that fits |
|---|---|
| "what is [term]" | A short definition paragraph |
| "how to [task]" | Numbered steps |
| "[X] vs [Y]" | A comparison table |
| "ingredients for [recipe]" | A bulleted list |
Measuring What Happens
Search Console’s Performance report groups results by query, page, country, device, and search appearance. Check the search appearance tab in your own report for the result types listed there, and compare clicks and impressions for the pages you expect to be excerpted, before and after a change. If impressions rise while clicks stay flat, read the excerpt itself: a box that answers the whole question gives the searcher less reason to visit than one that previews a longer answer.
