sitemap.xml
A `sitemap.xml` file is an XML format file that lists the pages of a website to help search engines crawl the site more effectively. Here’s a simple structure of a `sitemap.xml`:
```xml
http://www.example.com/
2023-10-01
daily
1.0
http://www.example.com/about
2023-10-01
monthly
0.8
http://www.example.com/contact
2023-10-01
yearly
0.5
```
Key elements in a `sitemap.xml`:
- <url>: This tag defines a single URL entry.
- <loc>: The location of the page.
- <lastmod>: The date when the content 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 the site (range from 0.0 to 1.0).
Using a `sitemap.xml` can improve your site's SEO by making it easier for search engines to find and index your pages.
