Google won’t index pages if they’re broken or blocked, and most sitemaps contain at least a few of them. You might submit a sitemap thinking you’re helping SEO, but if it's full of errors, you're actually wasting crawl budget.
The real issue is that sitemaps get ignored when they include 404s, noindex pages, or redirect chains. Most people miss this until rankings drop.
What Is a Sitemap Health Auditor?
Sitemap Health Auditor is a free browser-based tool that checks every URL in your XML sitemap for HTTP status codes, indexability, and basic structural issues. You don’t need to log in—just paste your sitemap URL and run the test.
It shows you exactly which pages are returning 404s, 500s, 301s, or are blocked by meta tags or robots.txt.
Why It Matters for SEO
Google recrawls most sites every 3-7 days, and crawl budget is limited. If Googlebot spends time on broken or blocked URLs from your sitemap, it won’t reach your good pages.
Here’s what actually happens: when 20% of your sitemap URLs return 404s, Google starts questioning the sitemap’s reliability. That means lower crawl priority. One site I audited lost 38% of its indexed pages in two months because its sitemap pointed to deleted content.
You can’t fix what you don’t see. A dirty sitemap quietly kills SEO momentum.
How to Use It
- Go to https://scrawl.tools/tools/sitemap-auditor (no login needed)
- Enter your sitemap URL (e.g., sitemap.xml or sitemap_index.xml)
- Click “Audit” and wait 30-60 seconds for the full breakdown
It’s free, fast, and works on any public sitemap. No account, no spam, no limits.
What the Results Tell You
You’ll see a color-coded list of all URLs with their status codes, indexability status, and redirect paths if any. Each row shows you exactly what’s wrong—like a 404, a noindex tag, or a redirect chain.
The tool flags duplicate URLs and canonical issues too. You’ll also get a final count of clean vs. problematic URLs.
Click any URL to see full response headers and meta tags. That saves time digging through dev tools or crawling with desktop software.
For deeper checks, export the CSV or cross-reference issues with the Redirect Chain Checker or Canonical Checker.
3 Mistakes Most People Make
- Submitting outdated sitemaps — You update content, delete old pages, but forget to regenerate the sitemap. Result? 80+ 404s sitting in your sitemap for months.
- Including noindex pages — Template pages, filters, or staging content accidentally slip in. Google sees the sitemap as a priority list—so it wastes time on pages you told it to ignore.
- Not checking redirect chains — A sitemap URL redirects to another URL that redirects again. That’s 2+ extra HTTP calls. Some tools miss this, but the Sitemap Health Auditor shows the full path.
Most people miss redirect depth because they only check status codes. The real issue is latency: 3+ hop chains delay indexing.
If you’re running a site with more than 100 pages, you should audit your sitemap every 4-6 weeks. I do it monthly on all client sites—it takes 5 minutes.
Your sitemap shouldn’t be a graveyard of dead pages. It should be a clean hit list of what you want Google to crawl and rank.
