Sitemap URL Checker for XML Sitemaps and URL Lists

Paste XML sitemap content or a URL list to check URL counts, duplicates, HTTPS usage, host consistency, lastmod values, and common sitemap issues locally in your browser.

Quick answer

A sitemap URL checker helps review sitemap entries before submission or deployment.

This tool analyzes pasted content and does not crawl URLs.

Best inputs

XML sitemap content

Paste the actual XML when you want lastmod and sitemap structure checks.

URL list

Paste one URL per line when you only need duplicates, hosts, protocol, and format checks.

What this checker looks for
It focuses on common sitemap hygiene issues that are easy to catch before deployment.

Checks include invalid URLs, duplicate URLs, HTTP URLs, multiple hosts, local URLs, query strings, missing lastmod, old lastmod dates, and the 50,000 URL sitemap limit.

It is a pre-publish QA helper, not a crawler.

Pair with live checks

After this local check, use your crawler, search console, or deployment audit to confirm HTTP status, redirects, canonical tags, noindex, robots.txt, and real fetchability.

Common use cases
These are the jobs people usually mean when they search for a sitemap checker or sitemap URL checker.

Pre-submit sitemap QA

Check URL count, duplicates, hosts, HTTPS, and lastmod values before submitting a sitemap.

Migration checks

Paste old and new URL lists to catch HTTP URLs, duplicate entries, and unexpected hosts.

Content launch review

Check a generated sitemap section before releasing new tool, blog, or product pages.

Developer handoff

Copy a summary of sitemap issues into QA notes, pull requests, or deployment checklists.

Example, assumptions, and limitations
Use this checker for local sitemap hygiene, then validate live URLs separately.

Example

Paste sitemap.xml content to find duplicate URLs, HTTP entries, local URLs, or missing lastmod values.

Assumption

The pasted XML or URL list is the sitemap content you plan to deploy or submit.

Limitation

The tool does not fetch URLs, check HTTP status, or prove that pages are indexable.

Frequently asked questions

Can this fetch a sitemap URL?

No. Paste the XML content or URL list into the tool. This keeps the checker purely browser-side.

Does this validate XML namespaces?

It parses common urlset and sitemapindex content, but it is focused on URL QA rather than full XML schema validation.

Should sitemap URLs be HTTPS?

Production sitemap URLs should usually use HTTPS and a consistent canonical host.

Does a sitemap guarantee indexing?

No. It helps discovery, but indexing depends on crawlability, canonical signals, content quality, and search engine decisions.

Suggested workflow

Sitemap release QA path

Use sitemap review after metadata, canonical, and robots signals are prepared.
