sitemap.xml
A `sitemap.xml` file is an XML file that provides search engines with information about the pages, videos, and other files on your site. This helps search engines crawl your site more intelligently. Here’s a simple structure of what a `sitemap.xml` might look 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
yearly
0.5
```
In this example:
- <url>: Represents a single URL entry.
- <loc>: The location 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 URLs on the site.
Creating a `sitemap.xml` file can improve your site's SEO and help ensure that search engines index your content effectively.
