A `sitemap.xml` is a file that helps search engines understand the structure of a website. It lists all the important pages, making it easier for crawlers to find and index them.
Here are some key components of a `sitemap.xml`:
- XML Declaration: Indicates that the file is an XML document.
- urlset: The root element that contains all the URLs.
- url: Each URL entry is wrapped in this tag.
- loc: Specifies the location (URL) of the page.
- lastmod: Indicates the last modified date of the page.
- changefreq: Suggests how frequently the page is likely to change.
- priority: Indicates the importance of the page relative to others on the site.
