Drop your sitemap.xml onto the upload area, or click it to browse. The file content loads into the editor. Click Check to scan for problems. Each result shows the line number, the code on that line, and a short note on what is wrong.
It catches XML syntax errors, wrong or missing namespace declarations, <url> entries without a <loc> tag, relative or malformed URLs, duplicate <loc> values, badly formatted <lastmod> dates, out-of-range <priority> values, invalid <changefreq> entries, unescaped & characters, and URL count or file size limits.
Red marks errors — problems that stop search engines from reading the file. Yellow marks warnings — issues that hurt crawl efficiency but do not block parsing.
Yes. The editor is fully editable. Fix a problem, click Check again, and the highlights and issue list refresh right away.
