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 and can improve your site's visibility in search engine results.
Here’s a basic structure of a `sitemap.xml`:
```xml
http://www.example.com/
2023-10-01
monthly
1.0
http://www.example.com/about
2023-09-01
monthly
0.8
http://www.example.com/contact
2023-08-15
yearly
0.5
```
In this example:
- <url>: Represents a single URL entry in the sitemap.
- <loc>: The location of the page.
- <lastmod>: The date the page was last modified.
- <changefreq>: How frequently the page is likely to change (e.g., daily, weekly, monthly).
- <priority>: The priority of the page relative to other pages on the site (between 0.0 and 1.0).
