A sitemap may look simple, but it plays a crucial role in helping Google discover, crawl, and index your website correctly. When your sitemap contains errors, missing pages, outdated URLs, or formatting problems, it can silently damage your SEO performance.
Many websites struggle to rank, not because of poor content or weak optimization, but because Google can’t properly understand or access their sitemap. The good news? Most sitemap issues are easy to fix — if you know what to look for.
In this guide, we break down the top sitemap errors that harm your SEO and show you how to fix them fast, using beginner-friendly steps and updated best practices for 2025.
1. Sitemap Includes URLs That Shouldn’t Be Indexed
One of the most common issues is when a sitemap contains pages that do not belong in Google’s index, such as:
-
admin pages
-
test pages
-
category duplicates
-
thin content pages
-
Thank you for the confirmation pages
-
private or archive pages
❌ Why This Hurts SEO
Google wastes crawl budget on unnecessary URLs, reducing the likelihood that your important pages are indexed quickly.
✅ How to Fix It
-
Remove low-value URLs from your sitemap
-
Only include pages that have SEO value
-
Check for accidental “noindex” + “in sitemap” conflicts
2. Sitemap Contains Broken or Redirected URLs
Redirected URLs (301/302) or non-existent URLs often appear in poorly generated sitemaps.
❌ Why This Hurts SEO
-
Google wastes crawl resources
-
Your sitemap becomes untrustworthy.
-
Slows down the indexing of new content
✅ How to Fix It
-
Scan your sitemap using tools like Screaming Frog, Ahrefs, or Search Console.
-
Remove 404 pages, redirected URLs, and outdated content
-
Keep your sitemap clean and updated weekly/monthly
3. Sitemap Is Too Large or Poorly Structured
Sitemaps should be lightweight and easy for search engines to process.
❌ Problems
-
Large sitemaps (50,000+ URLs)
-
Heavy XML formatting
-
Multiple sitemap versions scattered across directories
❌ Why This Hurts SEO
Google may struggle to parse or prioritize your pages thoroughly.
✅ How to Fix It

Split large sitemaps into smaller sections

Keep each sitemap clean, simple, and under Google’s limits
4. Missing or Incorrect Canonical URLs
A sitemap that lists URLs with incorrect canonical tags confuses search engines.
❌ Why This Hurts SEO
Google doesn’t know which page is the correct version, causing:
-
duplicate content issues
-
ranking dilution
-
indexing delays
✅ Fix
-
Ensure every sitemap URL matches the canonical version
-
Avoid mixing HTTP/HTTPS
-
Avoid mixing www and non-www versions

Many websites forget to refresh their sitemaps after publishing new content or updating URLs.
❌ Why This Hurts SEO
Google may continue crawling outdated pages and miss new ones.
✅ Fix
-
Automate sitemap generation
-
Regenerate your sitemap after content updates
-
Submit your updated sitemap to Google Search Console
6. Incorrect Sitemap Location or Missing Submission
Even a perfect sitemap won’t help if Google can’t find it.
❌ Wrong Practices
-
Sitemap not in the root directory
-
Sitemap not submitted in Search Console

No link in robots.txt
❌ Why This Hurts SEO
Google may take longer to discover your sitemap, or it may ignore it.

Place sitemap at: yourwebsite.com/sitemap.xml
-
Add sitemap to robots.txt
-
Submit the sitemap manually in Google Search Console
7. Including Non-Canonical or Duplicate URLs
Duplicate URLs with parameters, session IDs, or tracking codes should never appear in your sitemap.

Creates confusion for crawlers

Dilutes ranking signals

Causes indexing inconsistencies
✅ Fix
-
Only include clean, canonical URLs
-
Block parameter-based URLs in robots.txt

8. Sitemap Format Errors or Invalid XML
If your sitemap is poorly formatted or contains syntax errors, Google may reject it entirely.

Use proper XML tags

Ensure UTF-8 encoding
