sitemap.xml
A `sitemap.xml` file is an important tool for search engines, helping them understand the structure of a website. Below is a simple example of what a `sitemap.xml` file might look like:
```xml
http://www.example.com/
2023-10-01
daily
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:
- <urlset>: The root element that wraps all the URLs.
- <url>: Each URL entry within the sitemap.
- <loc>: The location of the URL.
- <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 structure helps search engines to crawl the website more effectively and understand which pages are more important.
