Sitemap Validator — free online tool
You built a sitemap for your site, but is it actually correct? A small mistake in the XML, or too many URLs in one file, can quietly stop search engines from reading it. We added a free tool that checks it for you — Sitemap Validator — right in your browser.
What it does
Paste your XML sitemap and it checks the structure right away. It counts how many URLs are inside, warns you if you've gone over the size limits, and lays out every URL in a clean, readable list so you can scroll through and spot anything that looks wrong.
Nothing leaves your device
The whole check runs inside your browser. Your sitemap isn't uploaded anywhere, and nothing is saved on a server. You can close the tab and there's no trace left behind.
How to use it
- Open Sitemap Validator and paste your XML sitemap into the box.
- Read the results: the URL count, any over-limit warnings, and the full list of links.
- Fix anything it flagged, then use your corrected sitemap with confidence.
It's free with no limit. There are more small tools on the Apps page.
