A structured file listing a site's important URLs to help search engines discover and prioritise them.
An XML sitemap is a machine-readable file that enumerates the canonical URLs a site owner wants crawled, optionally with metadata such as last-modified dates. It aids discovery, particularly for large sites, new sites or pages that are poorly internally linked, though it is a hint rather than a guarantee of indexing. A clean sitemap containing only indexable, canonical, 200-status URLs sends a clear quality signal to search engines.
