sitemap.xml
A `sitemap.xml` file is an XML file that lists the URLs for a site along with additional metadata about each URL. This helps search engines like Google to crawl a website more intelligently. Here’s a basic outline of what a `sitemap.xml` file might look like:
```xml
http://www.example.com/
2023-10-01
daily
1.0
http://www.example.com/about
2023-09-28
monthly
0.8
http://www.example.com/contact
2023-09-20
yearly
0.5
```
In this example:
- <url>: Represents each URL entry.
- <loc>: Specifies the location of the URL.
- <lastmod>: Indicates the last modification date of the URL.
- <changefreq>: Suggests how frequently the page is likely to change.
- <priority>: Indicates the priority of the page relative to other pages on the site.
This structure helps search engines understand the importance and update frequency of your web pages.
