What these rules do in Google Search
The free data-nosnippet generator writes the snippet controls Google documents: nosnippet, max-snippet, max-image-preview, max-video-preview and noindex as a robots meta tag or X-Robots-Tag header, plus data-nosnippet wrappers for single passages. It also explains what each rule does in AI Overviews and AI Mode.
Quick answer
data-nosnippet is an HTML attribute on span, div or section elements that tells Google not to use that text in a snippet. Page-wide, nosnippet blocks snippets and stops the content being a direct input for AI Overviews and AI Mode, while max-snippet limits it. Google-Extended does not control Google Search.
What is data-nosnippet?
data-nosnippet is an HTML attribute that marks part of a page as off limits for search snippets. Google's robots meta tag documentation says: "You can designate textual parts of an HTML page not to be used as a snippet", using the attribute on "span, div, and section elements". It is a boolean attribute, so any value is ignored, and an unclosed div hides everything after it.
The page level rules work on the whole URL. Google says nosnippet "applies to all forms of search results (at Google: web search, Google Images, Discover, AI Overviews, AI Mode) and will also prevent the content from being used as a direct input for AI Overviews and AI Mode". max-snippet sets a character limit and "will also limit how much of the content may be used as a direct input for AI Overviews and AI Mode". These rules, not Google-Extended, are how you limit what Google Search shows from a page.
How do you use the Nosnippet and Max-Snippet Generator?
- Choose whether the rules apply to all crawlers or to Google only.
- Tick noindex or nosnippet if you need them, or set a max-snippet length in characters. Leave it empty for no limit, or use -1 to let Google decide.
- Pick the image preview size and, for pages with video, a video preview length in seconds.
- Paste the text you want to keep out of snippets, such as a price or a quote, and choose span, div or section to wrap it.
- Copy the meta tag into the page head, or the X-Robots-Tag header into your server settings for PDFs and other files, and place the wrapper in your HTML.
How do nosnippet and max-snippet affect AI Overviews and AI Mode?
They are the controls Google names for its AI features. Google's guide to AI features and your website says: "To limit the information shown from your pages in Search, use nosnippet, data-nosnippet, max-snippet, or noindex controls." nosnippet stops the page being a direct input for AI Overviews and AI Mode, and max-snippet limits how much of it may be used. A strict limit also shortens your normal snippets, so test the trade off on a few pages first.
When should you use data-nosnippet instead of nosnippet?
Use data-nosnippet when only part of a page should stay out of snippets, such as a price that changes often, a quote you licensed or a spoiler. Use nosnippet when no part of the page should appear as a snippet. data-nosnippet leaves the rest of the page eligible, so it costs less visibility. Google warns not to add or remove the attribute with JavaScript on existing elements, because rendering is not guaranteed, so put it in the HTML your server sends.
Does Google-Extended stop AI Overviews?
No. Google's common crawlers page says Google-Extended manages whether crawled content may be used to train future Gemini models and for grounding, and that it "does not impact a site's inclusion in Google Search nor is it used as a ranking signal in Google Search". It is a robots.txt token with no user agent of its own. AI Overviews and AI Mode are part of Search, so the snippet rules on this page are the controls for them.
Quick reference: Google snippet rules
| Rule | What Google does | Effect on AI Overviews and AI Mode |
|---|---|---|
| noindex | Does not show the page in search results | Page not shown in Search |
| nosnippet | No text snippet or video preview | Content not used as a direct input |
| max-snippet:[number] | Snippet of at most that many characters; 0 equals nosnippet, -1 means Google decides | Limits how much content may be used as a direct input |
| max-image-preview:none, standard or large | Sets the largest image preview | Image preview size |
| max-video-preview:[number] | Video preview of at most that many seconds; 0 static image, -1 no limit | Video preview length |
| data-nosnippet on span, div or section | That text is not used as a snippet | Google lists it among the controls for AI features |
Worked example
Example
Example: a made-up agency wants short snippets, large image previews and its changing price kept out of results. With the default settings the tool outputs <meta name="robots" content="max-snippet:160, max-image-preview:large">, the matching header X-Robots-Tag: max-snippet:160, max-image-preview:large and the wrapper <span data-nosnippet>Prices start at 450 GBP per audit.</span>. The counters show 2 rules, a snippet limit of 160 and 0 warnings. Ticking nosnippet as well drops max-snippet and shows 1 warning, because the more restrictive rule applies.

Frequently asked questions
Does data-nosnippet hurt rankings?
Google does not describe it as a ranking factor. It only controls which text can appear in a snippet. Hiding too much can make your result less useful, so wrap only the passages that must stay out, such as prices or licensed quotes.
Can I use data-nosnippet on a p or li element?
No. Google supports it only on span, div and section elements, and its documentation marks other elements as not valid. Wrap the paragraph or list in a div, or the words in a span, and put the attribute there.
What is the difference between the meta tag and X-Robots-Tag?
They accept the same rules. The meta tag goes in the head of an HTML page. The X-Robots-Tag is an HTTP header your server sends, so it also works for PDFs, images and other files that have no HTML head.
What happens if a page has both nosnippet and max-snippet?
Google says that when robots rules conflict, the more restrictive rule applies, so nosnippet wins. The tool leaves max-snippet out in that case and shows a warning, which keeps the tag short and clear.
How long until Google respects new snippet rules?
Google has to recrawl the page first. Its AI features guide says crawling can take several days to several months, and you can request a recrawl. Use the URL Inspection tool to check that Googlebot sees the rule.
Do these rules work if robots.txt blocks the page?
No. Google can only read meta tags and headers on pages it is allowed to crawl. If robots.txt blocks a URL, Google says its indexing and serving rules will not be found and are ignored.
