sitemap.xml
A `sitemap.xml` file is an XML file that provides a structured list of the pages on a website. It helps search engines understand the organization of your site and can improve SEO. Here's a basic 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
2023-09-15
monthly
0.8
http://www.example.com/contact
2023-10-01
yearly
0.5
```
In this example:
- <url>: Represents a single URL entry.
- <loc>: The location of the page.
- <lastmod>: The last modification date of the page.
- <changefreq>: How often the page is likely to change.
- <priority>: The priority of the page relative to other pages on your site.
Having a well-structured `sitemap.xml` can help search engines crawl your site more effectively.
