Crawl errors are like potholes on the road to strong search engine rankings. They disrupt Google’s ability to access and index your content, which can hurt your SEO performance and visibility. The good news is that with tools like Google Search Console, you can identify and fix these issues before they impact your site traffic.
In this guide, we will break down what crawl errors are, why they matter, how to find them in Google Search Console, and most importantly, how to fix them effectively.
What Are Crawl Errors?
Crawl errors occur when Googlebot (Google’s web crawler) tries to visit a page on your site but encounters a problem. These issues prevent your content from being indexed properly, which means it might not show up in search results.
There are two main types of crawl errors:
1. Site Errors
These affect your entire site and stop Googlebot from accessing it at all. They are usually related to server connectivity issues, DNS errors, or a misconfigured robots.txt file.
2. URL Errors
These are specific to individual pages. The most common types include:
- 404 Not Found
- Soft 404s
- 403 Forbidden
- 500 Internal Server Errors
- Redirect errors
- Submitted URL marked ‘noindex’
Each error type can tell you something different about what is going wrong.
Why Crawl Errors Matter for SEO
If Google cannot access your pages, it cannot index them. And if your pages are not indexed, they will not appear in search results. That means lost traffic, lost visibility, and potentially lost revenue.
Some additional consequences include:
- Wasted crawl budget
- Poor user experience for visitors
- Reduced domain authority due to broken links
Fixing crawl errors is not just about SEO—it is also about maintaining the health and usability of your website.
How to Find Crawl Errors in Google Search Console
Before you can fix crawl errors, you need to locate them. Google Search Console provides detailed reports that show where and why Googlebot encountered problems.
Here is how to find them:
Step 1: Log into Google Search Console
Go to search.google.com/search-console and select the property (website) you want to inspect.
Step 2: Navigate to the “Pages” Report
On the left sidebar, click on the Indexing section, then select Pages. This report shows which pages are indexed and which are not.
Step 3: Review the “Not Indexed” List
Under the “Why pages aren’t indexed” section, you will see a list of issues. Look for errors such as:
- Page with redirect
- Soft 404
- Not found (404)
- Crawl anomaly
- Server error (5xx)
- Blocked by robots.txt
- Excluded by ‘noindex’
Click on each error type to see which URLs are affected.
How to Fix the Most Common Crawl Errors
Let’s walk through how to fix the most frequent crawl errors reported in Google Search Console.
1. 404 Not Found
What it means: The page no longer exists or the URL is typed incorrectly.
How to fix it:
- If the page was removed intentionally, set up a 301 redirect to a relevant page.
- If it was deleted by mistake, restore the content.
- Update any internal or external links pointing to that URL.
Pro tip: Do not redirect every 404 to the homepage. Always redirect to the most relevant content to preserve SEO value.
2. Soft 404
What it means: Google thinks a page returns a “Not Found” message but still shows a 200 (OK) status code.
How to fix it:
- Add proper content to the page if it is supposed to be live.
- If the page should not exist, return a real 404 or set up a 301 redirect.
Why it matters: Soft 404s confuse crawlers and can dilute your crawl budget.
3. Server Errors (5xx)
What it means: Your server failed to load the page when Googlebot tried to access it.
How to fix it:
- Check your hosting environment and error logs.
- Work with your web host to resolve server downtime or overload.
- Ensure your site is not blocking crawlers during traffic spikes.
Preventive step: Use uptime monitoring tools to get alerts if your site goes down.
4. Redirect Errors
What it means: The page has a redirect loop or chain that prevents successful loading.
How to fix it:
- Use tools like Screaming Frog or Ahrefs to identify long redirect chains.
- Update links to point directly to the final URL.
- Avoid redirect loops by limiting the number of hops between URLs.
5. Blocked by Robots.txt
What it means: Your robots.txt file is preventing crawlers from accessing a page.
How to fix it:
- Go to your
robots.txtfile (yourdomain.com/robots.txt). - Look for disallow rules that might be too broad.
- Use Google’s robots.txt Tester to verify access.
Warning: Be very careful when editing your robots.txt file. Mistakes here can block your entire site from Google.
6. URL Marked Noindex
What it means: The page has a meta tag or HTTP header telling search engines not to index it.
How to fix it:
- If the page should be indexed, remove the
<meta name="robots" content="noindex">tag. - If you want to keep the page out of search results, you can leave it alone.
Best practice: Make sure important pages do not accidentally contain noindex tags.
After You Fix the Errors: Request Validation
Once you have resolved the issue, it is important to let Google know.
How to request validation:
- Go back to the error page in Search Console.
- Click on the affected error.
- Hit the Validate Fix button.
Google will recheck the page and notify you when the issue has been resolved.
Tools to Help Diagnose Crawl Errors
Aside from Google Search Console, several third-party tools can help you dig deeper into crawl issues:
- Screaming Frog SEO Spider: Great for identifying broken links and redirect chains
- Ahrefs Site Audit: Helps visualize crawl depth and internal linking issues
- Semrush Site Audit: Flags crawl errors and explains how to fix them
- GTmetrix or Pingdom: Useful for spotting server and performance issues
Combining Search Console with these tools provides a full view of your website’s crawl health.
Best Practices to Avoid Future Crawl Errors
- Regularly audit your site with Search Console and crawling tools
- Keep internal links updated
- Set up redirects properly and avoid long redirect chains
- Optimize your server performance and uptime
- Avoid using broken or expired outbound links
- Do not block important sections of your site in robots.txt
Consistency is key. Crawl errors are often a sign of neglect or outdated content, so having a content maintenance schedule can make a big difference.
Final Thoughts
Crawl errors can be frustrating, but they are fixable. With the tools in Google Search Console, you can identify problems quickly and take meaningful action to restore access to your pages. Remember, search engines want to index your content, but they can only do that if you make your site accessible, error-free, and easy to navigate.
Addressing crawl errors not only improves your SEO but also enhances the user experience, keeps your website clean, and boosts your credibility with both search engines and visitors.
If you want your content to show up in search results and perform well, fixing crawl errors is a must, not a maybe.
