sitemap.xml
A `sitemap.xml` file is an XML file that helps search engines understand the structure of your website. It provides a list of all the pages on your site, which can improve indexing.
Here’s a simple example of how a `sitemap.xml` might look:
```xml
http://www.example.com/
2023-10-01
daily
1.0
http://www.example.com/about
2023-10-01
monthly
0.8
http://www.example.com/contact
2023-10-01
yearly
0.5
```
In this example:
- loc: The URL of the page.
- lastmod: The last modified date of the page.
- changefreq: How often the page is likely to change.
- priority: The priority of the URL relative to other pages on the site.
It's important to keep your `sitemap.xml` file updated whenever you make changes to your website. This helps search engines discover new content quickly.
