Practical guide
What is Sitemap Checker?
An XML sitemap lists canonical public URLs that you want search engines to discover. It can also include lastmod, changefreq, and priority hints, plus indexes that point to other sitemap files.
A useful sitemap contains final HTTPS destinations, stays within protocol size limits, and updates lastmod only when meaningful content changes. Validation catches missing locations and structural problems.
