A `sitemap.xml` file is an XML file that helps search engines understand the structure of a website. It provides information about pages, videos, and other files on the site, along with the relationships between them. Here’s a simple overview of its components:
- XML Declaration: Indicates that the file is an XML document.
- urlset Element: The root element that contains all the URLs.
- url Element: Each url element represents a single page on the site.
- loc: The URL of the page.
- lastmod: The date the page was last modified.
- changefreq: How often the page is expected to change (e.g., daily, weekly).
- priority: The priority of the page relative to other pages on the site.
Here is a basic example of a `sitemap.xml` file:
