sitemap.xml
A sitemap.xml file is an XML file that lists all the URLs of a website, helping search engines understand the structure of the site. Here is a basic example of how it looks:
```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>: This tag wraps around each URL entry.
- <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.
Using a sitemap.xml file can improve SEO by making it easier for search engines to crawl and index your site.
