A `sitemap.xml` file is an XML file that helps search engines understand the structure of your website. It contains a list of URLs for your site, along with additional information about each URL. Here's a simple breakdown of its components:
- URL Set: The main part of the sitemap, where each URL is listed.
- Last Modified: Indicates the last time the content of the URL was updated.
- Change Frequency: Suggests how often the page is likely to change (e.g., daily, weekly).
- Priority: Indicates the importance of the URL relative to other URLs on the site.
