What the Sitemap Checker Validates
Validate XML Sitemap Structure
Parse your sitemap.xml and check for proper XML formatting, valid tags, and correct URL entries. Detect malformed sitemaps before they cause crawling issues.
Find Broken URLs
Scan every URL in your sitemap and identify 404s, redirects, and server errors. Remove dead URLs to keep your sitemap clean and focused.
Discover Orphan Pages
Find pages that exist on your site but aren't in your sitemap. Orphan pages often miss out on crawling and indexing because search engines can't find them.
Check Sitemap Size & Limits
Verify your sitemap stays within Google's limits: 50,000 URLs per sitemap, 50MB uncompressed. Get warnings if you're approaching these limits.
Common Sitemap Issues We Detect
404 Not Found URLs
Pages in your sitemap that return 404 errors. These waste crawl budget and signal poor site maintenance.
Redirected URLs (301/302)
URLs that redirect to other pages. Update your sitemap to point to the final destination URL.
Noindexed Pages
Pages with noindex tags that are still in your sitemap. Remove them — they send conflicting signals.
Non-canonical URLs
URLs that aren't the canonical version. Your sitemap should only contain canonical URLs.
Exceeding Size Limits
Sitemaps over 50,000 URLs or 50MB. Split into multiple sitemaps with a sitemap index file.
Missing Lastmod Dates
Sitemaps without lastmod dates give Google no signal about freshness. Add accurate lastmod tags.

Frequently Asked Questions
What is a sitemap checker?
A sitemap checker is a tool that analyzes your XML sitemap to verify it's properly formatted, contains valid URLs, and follows search engine guidelines. It helps you find errors, broken links, and missing pages that could hurt your SEO.
Why is my sitemap important for SEO?
Your XML sitemap tells search engines which pages on your site are important and how often they change. A clean, accurate sitemap helps Google discover and index your pages faster. A sitemap with broken URLs or missing pages can waste crawl budget and hurt your indexation.
How often should I check my sitemap?
For most sites, monthly checks are sufficient. For large sites with frequent content changes (e-commerce, news), weekly checks are recommended. IndexLens offers daily automated monitoring that includes sitemap tracking.
What makes a good sitemap?
A good sitemap: (1) only includes URLs that return 200 status codes, (2) excludes noindexed pages, (3) stays within the 50,000 URL / 50MB limits, (4) uses proper XML formatting, (5) includes lastmod dates, and (6) is referenced in your robots.txt file.
