What Is an XML Sitemap in SEO?
An XML Sitemap is a machine-readable file (written in XML format) that lists all the URLs you want search engines to index.
It helps bots discover:
- Pages
- Posts
- Images
- Videos
- Categories
Example:
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>https://www.small-seo-tool.com/</loc>
<lastmod>2025-09-29</lastmod>
<priority>1.0</priority>
</url>
</urlset>
