Your results show exactly how search engines will read your sitemap. The status box gives a quick pass or fail, but the real insight comes from the stats grid and issue list. Critical errors — like missing <loc> tags or incorrect namespace — will block search engines from processing your file. Warnings flag issues like invalid priority values or non-standard changefreq entries that might still work but aren’t ideal. Duplicate URLs don’t break your sitemap, but they waste crawl budget and confuse search engines about which page version to index. Every issue comes with a line number, so you can jump straight to the problem and fix it fast.
