Common Sitemap Errors
❌ Critical Errors:
<!-- Missing XML declaration -->
<urlset>
<url>
<loc>relative/url</loc> <!-- Should be absolute -->
<lastmod>2024-13-45</lastmod> <!-- Invalid date -->
<priority>1.5</priority> <!-- Invalid priority -->
</url>
</urlset>
✅ Correct Format:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>https://example.com/page/</loc>
<lastmod>2024-01-15</lastmod>
<changefreq>monthly</changefreq>
<priority>0.8</priority>
</url>
</urlset>
