sitemap.xml
A `sitemap.xml` file is used to inform search engines about the pages on your website that are available for crawling. Here’s a simple structure of what a `sitemap.xml` file looks like:
```xml
http://www.example.com/
2023-10-01
monthly
1.0
http://www.example.com/about
2023-09-15
monthly
0.8
http://www.example.com/contact
2023-09-20
monthly
0.5
```
Here’s what each tag represents:
- <urlset>: The root element that contains all the URLs.
- <url>: Contains individual URLs.
- <loc>: The URL of the page.
- <lastmod>: The last modification date of the page.
- <changefreq>: How frequently the page is expected to change (e.g., daily, weekly, monthly).
- <priority>: The priority of the URL relative to other pages on the site (0.0 to 1.0).
This file should be placed in the root directory of your website to be easily accessible by search engines.
