When search engines or auditing platforms visit your site they expect a clean sitemap.xml. A broken or poorly formatted sitemap wastes crawl budget, hides new pages, and triggers avoidable health errors in reports.
A minimal sitemap must follow the Sitemaps XML protocol. Start by using UTF-8 encoding, include the XML declaration, and wrap every entry inside a <urlset> element with the official namespace. Here is a solid foundation:
<?xml version="1.0" encoding="UTF-8"?><urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"><url><loc>https://www.example.com/</loc><lastmod>2024-04-10</lastmod><changefreq>weekly</changefreq><priority>1.0</priority></url></urlset>
https://example.com/sitemap.xml with a 200 response, UTF-8 encoding, and application/xml content type200 responses and avoid query-string duplicates<lastmod> in YYYY-MM-DD (or full ISO 8601) so tools can prioritise recent contentnoindex, robots.txt-blocked, or paginated duplicatesrobots.txt and submit it to Google Search Console and Bing Webmaster Tools for extra visibility
