A `sitemap.xml` file is an XML file that helps search engines understand the structure of a website. It provides information about the pages, videos, and other files on the site, and the relationships between them. This can improve the site's visibility in search engine results.
Here’s a basic structure of a `sitemap.xml` file:
```xml
