sitemap.xml
A `sitemap.xml` file is used to inform search engines about pages on your site that are available for crawling. Here’s a simple structure of a typical `sitemap.xml` file:
```xml
http://www.example.com/
2023-10-01
monthly
1.0
http://www.example.com/about
2023-09-15
monthly
0.8
http://www.example.com/contact
2023-08-10
yearly
0.6
```
### Key Elements in `sitemap.xml`
- <url>: Represents a single URL entry.
- <loc>: The location of the page.
- <lastmod>: The date when the page was last modified.
- <changefreq>: How frequently the page is likely to change (e.g., daily, weekly, monthly).
- <priority>: The priority of the page relative to other pages on your site (range from 0.0 to 1.0).
This XML structure helps search engines index your site more effectively and understand the relationships between your pages.
