A `sitemap.xml` file is an XML document that helps search engines understand the structure of your website. It lists the URLs for a site along with additional metadata. Here’s a simple overview of its components:
- URL Set: The main element that contains all the URL entries.
- URL Entry: Each URL entry is defined with the url tag.
- loc: Specifies the URL of the page.
- lastmod: Indicates when the page was last modified.
- changefreq: Suggests how frequently the page is likely to change.
- priority: Indicates the importance of the page relative to other pages on the site.
Here’s an example of a simple `sitemap.xml` file:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap-image/1.1">
<url>
