Steps Add nosnippet to the robots meta tag or X-Robots-Tag header to suppress text snippets/previews entirely for a page Use max-snippet:[number] to cap the snippet length in characters (0 disables snippets, -1 allows unlimited) Set max-image-preview:none|standard|large to control the largest image preview size shown Set max-video-preview:[seconds] to cap animated video preview duration (0, a specific second count, or -1 for unlimited) Wrap specific on-page text in a data-nosnippet HTML element to exclude just that text from snippets while allowing the rest of the page Known gotchas When directives conflict (e.g. max-snippet:50 combined with nosnippet), the more restrictive rule wins These directives only affect Google's own snippet display - they don't block indexing or crawling, and other engines may not honor them identically Snippet-control directives are not documented to govern Google's separate AI Overviews sourcing/quoting behavior
