20 Reasons Why a Website is Not Crawled or Indexed by Search Engines and How to Fix
1. Robots.txt Issues
- Problem:
Incorrectly configured robots.txt file that blocks Googlebot.
- Solution:
Verify and update your robots.txt file using Google Search Console’s
robots.txt tester.
2. Noindex Meta Tags
- Problem:
Pages have <meta
name="robots" content="noindex"> preventing indexing.
- Solution:
Review and remove unintended noindex directives from meta tags.
3. Crawl Errors
- Problem:
DNS errors, server errors (5xx), or 404 errors preventing access.
- Solution:
Monitor Google Search Console for crawl errors and fix DNS/server issues
promptly.
4. Page Speed
- Problem:
Slow-loading pages impacting Googlebot’s crawl efficiency.
- Solution:
Optimize images, minify CSS/JavaScript, and utilize a Content Delivery
Network (CDN) for faster loading times.
5. Security Issues
- Problem:
Malware or phishing content detected, leading to blacklisting.
- Solution:
Conduct regular security audits, use HTTPS, and remove any malware
promptly.
6. Canonicalization Errors
- Problem:
Incorrect or missing canonical tags causing duplicate content issues.
- Solution:
Implement proper canonical tags to specify preferred URLs.

Use Google Search Console’s URL Parameters tool to manage how Googlebot
handles URLs with parameters.
8. Internal Linking
- Problem:
Poor internal linking structure leading to inaccessible pages.
- Solution:
Ensure all pages are properly linked internally to facilitate crawling.
9. Mobile-Friendliness
- Problem:
Website not optimized for mobile devices.
- Solution:
Use Google’s Mobile-Friendly Test tool to identify and fix mobile
usability issues.
10. JavaScript and AJAX

Content loaded dynamically via JavaScript or AJAX not accessible to
Googlebot.
- Solution:
Implement Progressive Enhancement or use server-side rendering for
critical content.

Missing or improperly formatted XML sitemap.
- Solution:
Create a comprehensive XML sitemap and submit it to Google Search Console.
