A `sitemap.xml` file is an XML document that helps search engines understand the structure of your website. It lists the URLs of your site along with additional metadata about each URL. This metadata can include information such as when the page was last updated, how often it changes, and its importance relative to other URLs on the site.
Here’s a basic structure of a `sitemap.xml` file:
```xml
http://www.example.com/
2023-10-20
monthly
1.0
http://www.example.com/about
2023-10-15
yearly
0.8
http://www.example.com/contact
2023-10-10
yearly
0.5
```
