A `sitemap.xml` file is an XML file that helps search engines understand the structure of your website. It provides information about the pages, videos, and other files on your site, and the relationships between them. Here’s a simple outline of what a `sitemap.xml` might include:
- URL: The web address of the page.
- Last Modified: The date when the page was last updated.
- Change Frequency: How often the content changes (e.g., daily, weekly, monthly).
- Priority: The importance of the page relative to other pages on the site (value between 0.0 and 1.0).
Here is an example of a simple `sitemap.xml` structure:
