sitemap.xml
A `sitemap.xml` file is an XML file that helps search engines understand the structure of a website. It lists all the important pages of the site, ensuring that search engines can crawl and index them efficiently.
Here’s a simple example of what a `sitemap.xml` 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:
- loc: The URL of the page.
- 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.
Having a well-structured `sitemap.xml` helps improve SEO and ensures that search engines can find all relevant pages on your website.
