A `sitemap.xml` file is an XML file that helps search engines understand the structure of your website. It lists the pages on your site to ensure that they can be indexed properly. Here’s a simple overview of its components:
- URL: Each page of your website that you want to be indexed.
- Last Modified: The last time the page was updated.
- Change Frequency: How often the page is likely to change (e.g., daily, weekly, monthly).
- Priority: The importance of the page relative to other pages on your site.
Here’s a basic example of how a `sitemap.xml` file looks:
http://www.example.com/
2023-10-01
monthly
1.0
http://www.example.com/about
2023-09-15
yearly
0.5
Including a `sitemap.xml` file on your site can improve its visibility and indexing. It's typically placed in the root directory of the website.
