sitemap.xml
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 and provides important information about them. Here’s a simple example of what a `sitemap.xml` might look like:
```xml
https://www.example.com/
2023-10-01
daily
1.0
https://www.example.com/about
2023-09-15
monthly
0.8
https://www.example.com/contact
2023-08-25
yearly
0.5
```
In this example:
- <loc>: The URL of the page.
- <lastmod>: The date the page was last modified.
- <changefreq>: How often the page is likely to change.
- <priority>: The priority of the page relative to other pages on the site.
Having a `sitemap.xml` can improve the chances of your pages being crawled and indexed by search engines.
