Diagnostic tool
Find every broken, redirected, and off-host URL in your sitemap
Your sitemap was correct when it was generated. Weeks or months later, pages get renamed, retired, or moved behind redirects — and the sitemap silently describes pages that no longer exist. A crawler reads it as your site’s own statement about itself, and every dead entry is the site saying something untrue.
How it works
01
Paste a sitemap URL
Enter the URL of your sitemap or sitemap index — public or authenticated, the tool fetches it over HTTPS.
02
We fetch everything
Sitemapaudit follows sitemap indexes to their child sitemaps, then requests every URL the sitemap claims exists — up to 500 entries per scan. Each URL is followed through up to 10 redirects.
03
Read the report
You get a plain-language summary and a colour-coded list: green for 200 OK, red for
4xx, amber for redirects. Off-host entries and lastmod anomalies (future
dates, identical timestamps) are flagged separately.
What it checks
HTTP status of every URL
200s, 4xx, 5xx, and redirects — counted and listed. No scores, no ratings, just the factual status code for each entry.
Redirect chain analysis
When a URL redirects, the tool shows the redirect path and the final destination. URLs that end up on a different host than the sitemap are flagged.
lastmod integrity
Detects future-dated timestamps and identical values across all entries — the signature of a generator stamping "now" on everything rather than tracking real changes.
Cross-host detection
Flags any URL whose final destination lives on a different host than the sitemap itself — a common sitemap error.
One answer per scan. No dashboard, no monitoring, no upsell.
This tool exists because you just got a Search Console error about your sitemap, or you have a hunch some pages were removed. It gives you the list of exactly which URLs are wrong, in plain language, and stops there. Nothing is saved, nothing is scheduled, nothing is emailed.
