sitemap.xml
A `sitemap.xml` file is an XML document that helps search engines understand the structure of your website. It provides a list of URLs along with additional information about each page, such as when it was last updated and how often it changes. Here’s a simple example of what a `sitemap.xml` might look like:
```xml
http://www.example.com/
2023-10-01
monthly
1.0
http://www.example.com/about
2023-09-15
yearly
0.8
http://www.example.com/contact
2023-10-01
yearly
0.6
```
In this example:
- <url>: Represents a single URL in the sitemap.
- <loc>: The location of the URL.
- <lastmod>: The last modification date of the page.
- <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 (value between 0.0 and 1.0).
Creating a `sitemap.xml` helps improve SEO by making it easier for search engines to discover and index your pages.
