Frequently asked questions
What does an XML sitemap help search engines do?
A sitemap lists canonical URLs you want search engines to discover and may include optional metadata such as last-modified dates.
What does this validator check?
It checks the provided XML for sitemap structure and common issues such as malformed locations, duplicate URLs and last-modified values.
Does a valid sitemap guarantee indexing?
No. A valid sitemap can help discovery, but search engines decide which URLs to crawl and index.
