### Key Elements of a Sitemap
- <url>: Represents a single URL in the sitemap.
- <loc>: The location or URL of the page.
- <lastmod>: The last modified 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 (range from 0.0 to 1.0).
Having a properly configured `sitemap.xml` can improve your site's SEO by making it easier for search engines to crawl and index your content.
