How to Fix Crawl Errors and Improve Your SEO

Crawl errors can significantly impact your website’s performance, hindering search engines from accessing and indexing your content effectively. Addressing these issues is crucial for maintaining your site’s health and optimizing its visibility in search engine results. Whether you’re managing your SEO strategy in-house or partnering with one of the Top SEO Agencies, understanding and resolving crawl errors is essential for improving your SEO. This guide will walk you through identifying, fixing, and preventing crawl errors to enhance your website’s performance.

What Are Crawl Errors?

Crawl errors occur when a search engine tries to access a page on your website but fails to do so. These errors can be divided into two main categories:

  1. Site Errors: These affect your entire website and prevent search engines from crawling it. They include DNS errors, server errors, and robots.txt errors.
  2. URL Errors: These affect specific pages on your site and include issues like 404 Not Found errors, soft 404 errors, and access denied errors.

How to Identify Crawl Errors

1. Use Google Search Console

Google Search Console is a powerful tool for identifying crawl errors. Log in to your account and navigate to the “Coverage” report under the “Index” section. This report will provide details on various crawl errors affecting your site.

2. Check Server Logs

Server logs can provide insights into crawl errors by showing the requests made by search engine bots and the responses they received. Analyzing these logs can help you identify patterns and specific issues.

3. Use SEO Tools

Tools like Screaming Frog, Ahrefs, and SEMrush can crawl your site and identify crawl errors. These tools provide detailed reports and recommendations for fixing the errors.

How to Fix Crawl Errors

1. Address Site Errors

  • DNS Errors: Ensure your DNS settings are correct and your server is responsive. Contact your hosting provider if necessary.
  • Server Errors: Monitor your server’s performance and address issues like downtime or slow response times. Upgrading your hosting plan or optimizing your server settings might be required.
  • Robots.txt Errors: Ensure your robots.txt file is correctly configured and not blocking important pages from being crawled. Use the “robots.txt Tester” tool in Google Search Console to check for issues.

2. Resolve URL Errors

  • 404 Not Found Errors: These occur when a page is missing. Redirect users to relevant pages using 301 redirects or recreate the missing content if necessary.
  • Soft 404 Errors: These happen when a page returns a 200 status code but displays a “Not Found” message. Update these pages to return a proper 404 status code or redirect them to relevant content.
  • Access Denied Errors: Ensure that your pages are accessible to search engine bots. Check your server permissions and ensure you’re not unintentionally blocking access through your .htaccess file or other server settings.

3. Fix Broken Links

Broken links can lead to crawl errors and a poor user experience. Use tools like Screaming Frog or Ahrefs to identify broken links on your site and update or remove them as necessary.

4. Submit a Sitemap

Submitting a sitemap to Google Search Console can help search engines understand the structure of your site and identify important pages. Ensure your sitemap is up-to-date and includes all relevant URLs.

How to Prevent Future Crawl Errors

1. Regularly Monitor Your Site

Regularly check Google Search Console and other SEO tools for crawl errors. Address any issues promptly to prevent them from impacting your SEO.

2. Maintain a Clean and Organized Site Structure

Ensure your site structure is logical and easy to navigate. Use clear and consistent URLs, and avoid creating unnecessary redirects or deep nesting of pages.

3. Optimize Your Site’s Performance

A fast and responsive site is less likely to experience server errors. Optimize your site’s performance by compressing images, leveraging browser caching, and using a content delivery network (CDN).


Crawl errors can significantly hinder your website’s SEO performance, but by identifying and fixing these issues, you can improve your site’s health and visibility. Whether you’re handling SEO internally or working with the Best SEO Agency, regular monitoring and proactive maintenance are key to preventing crawl errors and ensuring your content is easily accessible to search engines. By following these best practices, you’ll be well on your way to a more optimized and search-engine-friendly website.
