robots meta tag

A robots meta tag in the HTML head can specify noindex or nofollow for an individual page. Additional directives include noimageindex, max-snippet:-1 and notranslate, allowing more precise control over image indexing and previews. If robots.txt blocks the URL, crawlers cannot fetch the page to read its meta instructions. A page using noindex must therefore remain crawlable for the directive to be discovered.

Business applications and impact#

Provides flexible page-level control over indexing and search snippets.

Implementation guidance and considerations#
