sitemap.xml
A `sitemap.xml` file is an XML file that provides search engines with information about the pages on a website. It helps ensure that all important pages are indexed. Below is 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
2023-09-20
yearly
0.5
```
In this example:
- <url>: Represents a single URL in the sitemap.
- <loc>: Specifies the location of the web 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.
Using a `sitemap.xml` file can help improve SEO and ensure better visibility of your website in search engine results.
