A robots meta tag directive that tells search engines the maximum number of characters to display for a page’s snippet in search results.
Site owners who manage web content and SEO, particularly when reviewing search engine optimization directives.
01How Max-Snippet works
The directive is added either in the HTML as "> or via an X-Robots-Tag HTTP header. The is the maximum character count Google may show for the snippet. Setting it to 0 suppresses the snippet entirely, while -1 removes any limit, letting Google choose the length. If the directive is absent, Google decides the snippet length based on relevance and layout.
It’s a simple tag that limits how long the text preview under your link can be in Google search.
02What to do about it this week
First, audit a few key pages to see what snippet length Google currently shows. Decide whether you want a shorter preview to encourage clicks or a longer one to convey more information. Then add or adjust the max-snippet value in the meta tag or header. Use Google's URL Inspection tool to verify the directive is recognized, and monitor the Search Console performance report for changes in click-through rate over the next days.
03How to measure or notice Max-Snippet
Check the live search results for your page and count the characters of the displayed snippet (spaces included). Look at the page source or HTTP headers for the presence of max-snippet. In Google Search Console, the URL Inspection tool shows any indexing-related robots directives under 'Coverage'. A sudden change in snippet length after you edit the tag indicates the directive is taking effect.
04Common mistakes
- Setting max-snippet to a very low value like 10 characters, which makes the snippet unreadable and can lower CTR.
- Using the directive on non-HTML resources (PDFs, images) where Google ignores it, leading to confusion about why the snippet still appears.
- Confusing max-snippet with max-video-preview or max-image-preview; they control different rich result types.
- Forgetting to include the directive in the HTTP header when serving content via a CMS that strips meta tags.
- Assuming the limit applies to the title tag; max-snippet only affects the snippet description, not the title.
05Limits and confusions
Max-snippet only influences Google's web search snippet; other search engines may ignore it. It does not affect video or image previews, which have their own max-video-preview and max-image-preview directives. The directive is also ignored when Google shows a rich result (like a FAQ or recipe) that pulls content from structured data rather than the meta description. Finally, if a nosnippet directive is present, max-snippet has no effect because no snippet is shown at all.

<meta name="robots" content="max-snippet:160">
Frequently asked questions
How does max-snippet differ from nosnippet and data-nosnippet?
Max-snippet sets a character limit for the snippet, while nosnippet prevents any snippet from appearing and data-nosnippet marks specific HTML sections to exclude from snippets.
When should I use max-snippet instead of letting Google choose the snippet length?
Use max-snippet when you want a preview but need to protect key content or comply with legal requirements; otherwise Google's automatic snippet usually performs well for click-throughs.
What happens if I set max-snippet to 0 — does it behave like nosnippet?
Setting max-snippet:0 tells Google to show no snippet at all, effectively the same as nosnippet for that page.
Does max-snippet still control snippets in AI Overviews and other AI-generated results?
Max-snippet does not currently control the length of AI Overview citations; those are generated separately and may display more content than the standard snippet limit.
What are the risks of setting max-snippet too low on commercial pages?
A very low limit can reduce click-through rates because users see too little context to decide if the page answers their query.
After updating max-snippet, how long until Google reflects the change in search results?
Changes typically appear within a few days after Google recrawls the page, but you can accelerate it by requesting indexing in Search Console.
Asked out loud
spoken, not typedThe same term in the words somebody uses speaking to an assistant rather than typing into a box — written from the situation, which is why each one carries the situation it came from.
Yes, add <meta name="robots" content="max-snippet:160"> in the page head to cap the snippet at 160 characters; Google will respect it once the page is recrawled.
It depends on why it broke — if the snippet exceeds your max-snippet value, Google may ignore the directive; check the live result and adjust the limit or improve the meta description.
Yes, max-snippet limits how many characters Google shows in the standard web snippet, but it does not restrict AI Overviews or other search features that might surface more text.
