sitemap.xml
A sitemap.xml file is an XML file that provides search engines with information about the pages on a website. It helps them crawl the site more effectively. 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
2023-09-20
monthly
0.5
```
In this example:
- loc: The URL of the page.
- lastmod: The last modification date of the page.
- changefreq: How often the page is likely to change (e.g., daily, weekly, monthly).
- priority: The priority of the page relative to other pages on the site (from 0.0 to 1.0).
Creating a sitemap.xml helps improve a site's SEO by ensuring that search engines can find and index all important pages.
