sitemap.xml
A `sitemap.xml` file is an XML file that helps search engines understand the structure of a website. It lists the URLs for a site along with additional information about each URL, such as how often it is updated and its importance relative to other URLs on the site.
Here is a simple example of what a `sitemap.xml` file might look like:
```xml
http://www.example.com/
2023-10-01
daily
1.0
http://www.example.com/about
2023-09-15
monthly
0.8
http://www.example.com/contact
2023-09-10
yearly
0.5
```
In this example:
- <loc>: Specifies the URL of the page.
- <lastmod>: Indicates when the page was last modified.
- <changefreq>: Suggests how frequently the page is likely to change (e.g., daily, weekly, monthly).
- <priority>: Indicates the priority of the page relative to other pages on the site, ranging from 0.0 to 1.0.
This file is useful for improving SEO and ensuring that search engines can efficiently crawl and index the site.
