XML Sitemap Validator for people who need an answer, not another export.
XML Sitemap Validator is built for a focused SEO question: Paste sitemap XML and validate URL count, malformed loc tags, duplicate URLs, http URLs, and lastmod date quality. The tool gives a practical answer from the URL, XML, CSV, or text you provide so you can decide what to fix, write, compare, or investigate next.
What this tool checks
- The input you provide, using transparent rules.
- Signals that can be calculated without paid third-party databases.
- Warnings that point to the next practical action.
- Copy-ready output where the tool generates markup, rules, or planning artifacts.
How to use it
- Paste the requested input.
- Run the tool.
- Review the result and warnings.
- Use the output for the next SEO action or move it into a PageOptimized project.
How to read the result
- Use passes as confirmation, not as a reason to stop reviewing the page.
- Treat warnings as prioritization signals.
- Pair one-off results with project history when the decision affects clients or recurring work.
What it will not fake
- It does not fake proprietary data.
- It does not replace a full project audit.
- It does not store recurring history outside PageOptimized.
Move from one answer to a repeatable process.
A free tool is useful for one decision. PageOptimized is for the recurring version of that decision: saving the check, attaching it to a project, turning evidence into work queue tasks, keeping history, and showing clients what changed without rebuilding the story in a spreadsheet.
