A `sitemap.xml` file is an XML document that provides information about the pages on a website. It helps search engines understand the structure of the site and improves the indexing of its content. Here’s a basic overview of what a `sitemap.xml` might contain:
- URL Set: A collection of URLs for the pages on the website.
- URL Element: Each URL is defined within a url tag.
- Required Tags:
- loc: The URL of the page.
- lastmod: The last modification date of the page.
- changefreq: How frequently the page is likely to change.
- priority: The priority of the page relative to other pages on the site.
Here’s an example of a basic `sitemap.xml` structure:
