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