Index health, at a glance.

An XML sitemap is a file that lists the URLs on your site you want search engines to know about, optionally with metadata like the last-modified date, change frequency, and priority. It doesn't guarantee indexing, but it's the most direct way to tell Google and Bing which pages exist — especially valuable for large sites, new sites with few backlinks, and pages that are hard to reach by crawling links alone.

A single sitemap can hold at most 50,000 URLs (and must stay under 50 MB uncompressed). Larger sites split their URLs across multiple sitemaps and use a sitemap index — a sitemap of sitemaps — to point to them all from one file. This inspector follows index files automatically and totals the URLs across every child sitemap it references.

The lastmod tag tells search engines when a URL last changed, which helps them prioritize recrawling pages that actually have new content. Accurate lastmod values can speed up how quickly updates are reflected in search, while missing or always-current lastmod dates waste the signal. This tool reports your lastmod coverage so you can see how many URLs are giving crawlers that hint.

Add a reference to it in your robots.txt (Sitemap: https://example.com/sitemap.xml) and submit the URL in Google Search Console under the Sitemaps report, and in Bing Webmaster Tools. Validate the file first — a sitemap with broken XML, redirects, or non-200 URLs can be ignored. Use this inspector to confirm it parses cleanly and lists what you expect before you submit.

No — your sitemap should list only canonical, indexable URLs you want in search results. Leave out redirects, pages blocked by robots.txt, noindex pages, duplicates, and parameter variants. A clean sitemap of only your best canonical URLs sends a clearer signal than a bloated one. If the inspector shows far more (or fewer) URLs than you publish, that mismatch is usually worth investigating.
