A `sitemap.xml` file is an XML document that helps search engines understand the structure of a website. It provides a list of URLs for a site along with additional information about each URL. Here’s a simple breakdown of its components:
- XML Declaration: Indicates that the document is in XML format.
- URL Set: The root element that contains all the URL entries.
- URL Entry: Each URL entry typically includes:
- loc: The location of the webpage (URL).
- lastmod: The last modified date of the webpage.
- changefreq: How frequently the page is likely to change (e.g., daily, weekly).
- priority: The priority of the webpage relative to other pages on the site.
Here’s a simple example of a `sitemap.xml` file:
