sitemap.xml
A `sitemap.xml` file is used to inform search engines about pages on a website that are available for crawling. It can help improve the visibility of your website in search results. Here's a simple structure of a `sitemap.xml` file:
```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
2023-10-10
yearly
0.5
```
In this example:
- <url>: Represents a single URL entry in the sitemap.
- <loc>: Specifies the location (URL) 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.
Using a `sitemap.xml` can enhance SEO by ensuring that search engines can easily find and index the pages on your site.
