sitemap.xml
A `sitemap.xml` file is an XML file that provides information to search engines about the pages, videos, and other files on your site. This helps search engines crawl your site more effectively. Here’s a simple structure of a `sitemap.xml` file:
```xml
http://www.example.com/
2023-10-01
weekly
1.0
http://www.example.com/about
2023-10-01
monthly
0.8
http://www.example.com/contact
2023-10-01
yearly
0.5
```
In this example:
- <url>: Represents a URL entry.
- <loc>: Specifies the location of the page.
- <lastmod>: Indicates the last modification date of the page.
- <changefreq>: Suggests how frequently the page is likely to change.
- <priority>: Assigns a priority to the page relative to other pages on the site.
This structure helps search engines understand the importance and update frequency of your site's content.
