A `sitemap.xml` file is an XML file that helps search engines understand the structure of a website. It provides a list of URLs on your site, along with metadata about each URL, such as when it was last updated, how often it changes, and its importance relative to other URLs on the site.
Here’s a simple example of how a `sitemap.xml` file is structured:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap-image/1.1">
<url>
<loc>http://www.example.com/</loc>
<lastmod>2023-10-01</lastmod>
<changefreq>weekly</changefreq>
<priority>1.0</priority>
</url>
<url>
<loc>http://www.example.com/about</loc>
<lastmod>2023-09-15</lastmod>
<changefreq>monthly</changefreq>
<priority>0.8</priority>
</url>
<url>
<loc>http://www.example.com/contact</loc>
<lastmod>2023-08-25</lastmod>
<changefreq>yearly</changefreq>
<priority>0.5</priority>
</url>
</urlset>
```
