A `sitemap.xml` file is an XML file that helps search engines understand the structure of a website. It lists the pages of a website to improve its indexing. Here’s a simple overview of its components:
- URLset: The root element that contains all the URLs.
- URL: Each URL entry contains several child elements.
- loc: The location of the URL.
- lastmod: The last modified date of the URL.
- changefreq: How often the URL is likely to change.
- priority: The priority of the URL relative to other URLs on the site.
Here is a simple example of a `sitemap.xml`:
