Do snippet limits apply to information supplied as structured data?

Definition: Google treats information supplied through structured data separately from text that it extracts automatically for a search snippet. Robots snippet limits generally do not affect structured-data information used for rich results, with a documented exception for description values.

Key facts

• Google's robots metadata reference says robots meta tags govern the amount of content Google extracts automatically from a page for search results.
• The same reference says robots meta tag limitations do not affect structured data, except article.description and description values for structured data defined for other creative works.
• For those description values, Google says to use max-snippet to set the maximum length of a preview.
• A max-snippet limit can restrict a text preview while information supplied through structured data for rich results remains outside that limit.
• Google's general structured data guidelines say structured-data pages should remain accessible to Googlebot and should not be blocked with robots.txt, noindex, or another access control method.

What does a snippet directive control?

Google separates automatic extraction from information that a publisher supplies in structured data. The robots metadata reference describes nosnippet as a rule that prevents a text snippet or video preview, and describes max-snippet:[number] as a maximum character count for a textual snippet. These are page or text controls for search presentation.

For example, the reference shows this page-level setting:

<meta name="robots" content="max-snippet:20">

The value sets a limit for a text snippet. It does not set a general character limit on every property that appears in structured data.

Which structured-data information is covered?

The documented exception concerns article.description and description values for structured data specified for other creative works. Google directs publishers to use max-snippet when they want to limit the length of a preview based on those description values.

The same documentation gives recipe structured data as an example. A recipe can remain eligible for a recipe carousel when its ordinary text preview is limited. Google also states that a max-snippet rule does not apply when the information is provided through structured data for rich results. This makes the property carrying the information important: a description value has the documented connection to the text-preview limit, while other rich-result information follows the structured-data treatment.

How should a website control the information?

Google says to manage structured data by changing the structured-data types and values, adding or removing the information that the site wants to make available. The reference also states that structured data remains usable for search results when it is declared inside an element with data-nosnippet.

The general structured data guidelines add two operational conditions. Structured data must represent the page content, and Google lists content hidden from the user as a reason structured data may fail to appear. Google also says, “Don't block your structured data pages to Googlebot using robots.txt, noindex, or any other access control methods.” A page-level snippet directive and the markup's own values therefore need separate review.

How can you check the distinction?

Read the page's robots meta tag or X-Robots-Tag for nosnippet and max-snippet, then inspect the structured-data properties on the same page. If a description is the intended preview source, compare it with the max-snippet setting. For other rich-result properties, review the type and values themselves because Google documents those as the controls for what the structured data makes available.

Google's structured-data guidelines mention the Rich Results Test, while also explaining that correct markup alone does not make a search appearance certain. The page must satisfy the relevant structured-data and content policies, and Google decides which search presentation is appropriate.

FAQ

Does max-snippet limit every field in structured data?

No. Google documents the limit for text snippets and for article.description or description values used by other creative works. Information supplied through structured data for rich results has a separate treatment.

Does data-nosnippet hide structured data from Google?

No. Google's robots metadata reference says structured data remains usable for search results when it is declared within a data-nosnippet element.

Should a page with structured data be blocked from Googlebot?

Google's structured-data guidelines say not to block structured-data pages with robots.txt, noindex, or another access control method. The page also needs structured data that represents content available to users.
