Common issues
No common sitemap issues found in this input.
Lastmod notes
Missing lastmod: 0. Older than one year: 0.
Crawler note
This checker finds common sitemap hygiene issues in pasted text. It does not fetch URLs, confirm indexability, or guarantee search engine indexing.
A sitemap URL checker helps review sitemap entries before submission or deployment.
This tool analyzes pasted content and does not crawl URLs.
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.
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.
After this pasted-content check, use your crawler, search console, or deployment audit to confirm HTTP status, redirects, canonical tags, noindex, robots.txt, and real fetchability.
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
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.
Can this fetch a sitemap URL?
Paste the XML content or URL list into the tool. Analysis is designed to run in the browser based on the current public implementation.
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 ensure 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.
