Sitemap Validator

A sitemap with broken entries does more harm than no sitemap at all, because it sends crawlers to pages that do not exist or should not be indexed. Checking the file before submission catches bad URLs, empty entries, and missing structure while they are still easy to fix.

This validator parses pasted sitemap XML, extracts every loc entry, and reports how many URLs were checked and how many had problems. It is the checking counterpart to the generator: one builds sitemaps, the other verifies them, and using both in sequence is the safe workflow.

Quick Answer: Check pasted sitemap XML and report invalid or empty URL entries.

Frequently Asked Questions

What does the Sitemap Validator do?

The Sitemap Validator takes pasted sitemap XML and turns it into a report of URL counts and problems, right in your browser. You do not need to install anything or create an account, and the result is ready in seconds. It is built for everyday jobs where you want a quick, reliable answer without opening a heavy desktop program or uploading your files anywhere.

Is my input private when I use this tool?

Yes. Everything you type, paste, or upload is processed locally in your own browser tab, so it never travels to a server run by this site. The only exception is a feature that explicitly needs a device, such as a camera or microphone, and even then the media stays on your device. Closing the tab ends the session, and nothing about your input is stored on the site.

What should I do if the result looks wrong?

First, check the input for typos, missing values, or an unsupported format, because most unexpected results come from the input rather than the tool. Try a small, simple example you can verify by hand, then compare it with the tool output. If the simple case works and the real case does not, the difference usually points to the part of the input that needs fixing.

What counts as a problem?

An empty loc entry, a URL that does not start with http, or a file with no loc entries at all. Those are the structural faults that make crawlers distrust or ignore a sitemap.

Does it check whether the URLs actually load?

No. This validator checks the sitemap structure and URL form in your browser. Checking live status needs a crawler, since browsers block cross-site status checks, so pair this with a crawl report for full coverage.

Can I use this tool on a mobile phone?

Yes. The tool is built with the same responsive layout as the rest of the site, so controls, inputs, and results adapt to a phone screen. Buttons are large enough to tap comfortably, text fields accept mobile keyboards, and results wrap instead of overflowing. If a feature needs a device capability, such as a camera, the tool will say so on that device rather than failing silently.
