A `sitemap.xml` file is an XML file that provides search engines with a list of pages on a website to ensure they can discover and index them effectively. Here are some key points about it:
- Purpose: Helps search engines understand the structure of your website.
- Format: Must follow XML format.
- Components:
- URL: The web address of the page.
- Lastmod: The date the page was last modified.
- Changefreq: How frequently the page is expected to change.
- Priority: The priority of the page relative to other pages on the site.
- Location: Typically placed in the root directory of the website.
- Submission: Can be submitted to search engines through their webmaster tools.
Here is a simple example of a `sitemap.xml` file:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap-image/1.1">
<url>
<loc>http://www.example.com/</loc>
<lastmod>2023-10-01</lastmod>
