A `sitemap.xml` file is used to inform search engines about pages on your site that are available for crawling. It helps search engines understand the structure of your website and find all its content. Here’s a simple overview of its components:
- XML Declaration: Indicates that the document is an XML file.
- URL Set: The root element that contains all the URLs.
- URL Entries: Each URL entry includes:
- loc: The URL of the page.
- lastmod: The date the page was last modified (optional).
- changefreq: How frequently the page is expected to change (optional).
- priority: The priority of the page relative to other pages on your site (optional).
Here’s a simple example of a `sitemap.xml` file:
