The max-snippet robots directive is a numeric parameter that limits the maximum number of characters Google may display in the text snippet beneath a search result for a given page. It is delivered via the meta robots tag (content=“max-snippet:50”) or an X-Robots-Tag HTTP header. Setting max-snippet:0 suppresses the snippet entirely, equivalent to nosnippet. Setting max-snippet:-1 grants Google unlimited snippet length, which is the default behaviour when no directive is present. Values between those extremes allow a partial snippet of approximately the specified character length. The directive was introduced by Google in September 2019 alongside max-image-preview and max-video-preview as a response to European publishers concerned about news snippet copyright following implementation of Article 11 of the EU Copyright Directive. Bing and other major crawlers also honour the directive. It has no effect on indexing or ranking, only on how much text is displayed in the search result.
