sitemap.xml
A `sitemap.xml` file is an XML file that helps search engines understand the structure of a website. It lists the pages of a site to ensure that search engines can find and crawl them effectively. Below is a simple example of what a `sitemap.xml` file might look like:
```xml
http://www.example.com/
2023-10-01
weekly
1.0
http://www.example.com/about
2023-09-15
monthly
0.8
http://www.example.com/contact
2023-09-10
yearly
0.5
```
In this example:
- <url>: Represents a single URL on the website.
- <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>: Indicates the priority of the page relative to other pages on the site.
Including a `sitemap.xml` file on your website can help improve search engine optimization (SEO) and ensure that all important pages are indexed.
