XML Sitemap Analyzer – Sitemap Health Check

How to Use the Analyzer

1. Paste your sitemap XML (from your sitemap's source) or enter its URL. Pasting is recommended — it works for any sitemap, even protected ones.
2. Optional: toggle the live status check to verify a sample of URLs for redirects, 404s, noindex and canonical mismatches.
3. Click "Analyze Sitemap" — structural results appear instantly; live checks run in the background.
4. Export the report (TXT) or the URL list (CSV) to track fixes.

What This Tool Checks

• XML validity — parse errors, malformed tags, bad root element.
• Sitemap index detection — the file references child sitemaps instead of URLs.
• URL quality — absolute http(s) URLs, no # fragments, no unescaped characters, reasonable length.
• Duplicates — the same URL listed twice.
• HTTP vs HTTPS — non-secure URLs flagged.
• lastmod coverage — percentage of URLs with a modification date.
• Live checks (sample) — status codes (redirects, 404s), noindex pages, canonical mismatches.

Sitemap Best Practices

• Include only indexable URLs — no noindexed pages, no redirecting URLs, no thin pages you want out of the index.
• Use absolute, lowercase, https URLs that match your canonical tags exactly.
• Keep lastmod honest — update it when the page actually changes; stale dates train engines to ignore it.
• Stay under limits — 50,000 URLs / 50MB per file, or use a sitemap index.
• Reference the sitemap in robots.txt and submit it in Search Console.

Example: Finding the Problem Page

A 1,200-URL sitemap scored 61/100. The analyzer found 3 invalid entries (one with a space, two missing protocols), 14 duplicates, 22 HTTP URLs, and one child that 404'd. After deduplication, fixing the invalid entries, and switching the HTTP URLs to HTTPS, the same file scored 96/100 — and the "Submitted URL not found (404)" report in Search Console cleared within two weeks.

Common Mistakes & How to Avoid Them

• Auto-generating without review. CMS sitemap plugins happily include trash, drafts and archive pages. Audit what gets listed.
• Listing redirecting URLs. The sitemap should contain the final destination, not the redirecting source.
• Mixing www/non-www or http/https. One canonical form across the entire sitemap.
• Trusting the "last generated" date. Your sitemap file's mtime is not lastmod — the page's content change date is.

Frequently Asked Questions

Does a sitemap guarantee indexing?

No. A sitemap is a discovery hint. Pages still need to be worth indexing — quality content, internal links and no conflicting directives.

Why does the live check sometimes fail?

Browsers cannot reach every server (CORS, robots, firewalls, rate limits). The tool reports unreachable URLs honestly and suggests re-running with pasted XML for the structural checks.

Should images and videos be in the sitemap?

Yes, via the image and video sitemap extensions — but keep the same page URL as the loc; the media are child entries.
