Clear filtersMeta description
A page description supplied in meta name="description". Search engines may use it or choose another content excerpt. It should accurately describe the page; it is not guaranteed search-result wording.
Definition and sourcesMeta robots
Instructions to supporting crawlers about indexing or result presentation, supplied in HTML or X-Robots-Tag. Crawlers must access the response to read noindex. These instructions are not access controls.
Definition and sourcesMeta tags
HTML meta elements supplying metadata such as encoding or a description. Page titles use the separate title element. Adding meta keywords does not improve Google rankings.
Definition and sourcesMobile-first indexing
Google's use of mobile content for indexing and ranking. It does not mean a separate phone-only index; content parity between views matters.
