A sitemap.xml file is an XML file that lists the URLs for a site along with additional metadata about each URL. This helps search engines like Google to crawl the site more intelligently. Here's a simple overview of its structure and components:
- XML Declaration: Specifies the XML version and character encoding.
- URL Set: The root element of the sitemap.
- URL Entry: Each URL is enclosed in a url tag, which contains the following sub-elements:
- loc: The URL of the page.
- lastmod: The last modified date of the page.
- changefreq: How frequently the page is likely to change.
- priority: The priority of this URL relative to other URLs on the site.
Here is a basic example of a sitemap.xml:
