Sitemap
Typically formatted as XML, a sitemap acts as a directory for crawlers, especially useful for large sites or pages that might not be easily discovered through internal links alone.
A sitemap speeds up discovery; it does not guarantee indexing. A page listed in a sitemap but blocked, thin or duplicated will still be skipped. Treat it as a way of saying which pages exist and when they last changed — not as a substitute for the internal linking that tells a crawler which of them matter.
A complete, up-to-date sitemap reduces the chance that new or updated content — like freshly published glossary terms — goes undiscovered by crawlers for weeks.
A site submits its XML sitemap to Google Search Console, ensuring newly published glossary and guide pages get discovered and crawled promptly.
