sitemap.xml
A `sitemap.xml` file is an XML file that lists the pages of a website to help search engines like Google better crawl the site. Here’s a simple structure of what a `sitemap.xml` 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
2023-10-10
yearly
0.5
```
In this example:
- <url>: Represents a single URL on your site.
- <loc>: The location of the page.
- <lastmod>: The last modified date of the page.
- <changefreq>: How frequently the page is likely to change.
- <priority>: The priority of the page relative to other pages on the site.
This helps search engines understand which pages to crawl and index. Make sure to update your `sitemap.xml` regularly as you add or change content on your site.
