Finding crawl errors in Google Search Console is one of the most useful technical SEO tasks for website owners, bloggers, marketers, and agencies. If Google cannot crawl important pages properly, those pages may struggle to appear in search results or may be discovered more slowly than they should be.
The good news is that Google Search Console gives you a practical way to spot these problems, understand what they mean, and prioritise fixes. Used properly, it can help you improve crawlability, indexing, site structure, and overall search visibility without guesswork.
What crawl errors mean
Crawl errors happen when Googlebot tries to access a page on your site but runs into a problem. That problem might be a server issue, a broken link, a redirect chain, a blocked page, or an error caused by website structure or settings.
In Google Search Console, crawl-related issues are usually reported as problems with pages not being indexed, pages being blocked, or server errors during crawling. For SEO beginners, the important point is simple: if Google cannot reliably reach a page, that page is less likely to perform well in organic search.
Where to find crawl errors in Google Search Console
Start by opening your property in Google Search Console. Once you are inside, there are a few places to check depending on the type of issue you are looking for.
Pages report
The Pages report is the main place to look for indexing and crawl-related problems. It shows which pages are indexed, which are not indexed, and the reasons Google gives. Common crawl-related reasons include server errors, redirect issues, blocked resources, and pages that could not be fetched.
URL Inspection
The URL Inspection tool is useful when you want to check one specific page. Paste the URL into the search bar at the top of Search Console to see whether Google can crawl it, whether it is indexed, and whether there are issues preventing indexing.
Sitemaps report
The Sitemaps report helps you confirm whether your submitted sitemap is being read correctly. If important URLs are missing from the sitemap or if the sitemap itself contains errors, crawl discovery can become less efficient.
How to diagnose the problem
Once you find a crawl issue, the next step is to understand the cause. Search Console gives you the symptom, but you still need to investigate the source of the problem on your website.
For example, if the report says a page was excluded because of a redirect, check whether the redirect is intentional and whether it points to the correct destination. If the problem is a 404 error, confirm whether the page was deleted on purpose or whether the link is broken by mistake.
It can also help to compare Search Console data with your server logs, analytics, and a technical SEO crawl using tools such as Screaming Frog. If you want broader support while learning how audits fit together, Backlink Works can be a useful SEO learning resource for understanding site health checks and crawlability.
Pay attention to these common causes:
- Broken internal links pointing to removed or misspelt URLs
- Server errors such as 5xx responses
- Incorrect robots.txt rules blocking important pages
- Pages marked with noindex unintentionally
- Redirect chains or redirect loops
- Duplicate URLs created by filters, parameters, or inconsistent internal linking
- Slow or unstable pages that are difficult for Googlebot to fetch
Practical checklist for checking crawl errors
Use this checklist when reviewing crawl errors in Search Console:
- Open the Pages report and review all excluded or error statuses
- Inspect any important URL that is not indexed
- Check whether the issue affects one page, a folder, or the whole site
- Test the live URL to see how it behaves for Google
- Review robots.txt, meta robots tags, and canonical tags
- Look for broken internal links in menus, content, footers, and related posts
- Confirm that your XML sitemap includes only indexable canonical pages
- After fixing the issue, request validation in Search Console if available
Common mistakes to avoid
Many crawl issues are made worse by simple mistakes during website management. Avoid these problems when checking Search Console.
- Ignoring non-indexed pages without checking the reason
- Blocking pages in robots.txt when they still need to be crawled
- Using noindex tags on pages that should rank
- Leaving outdated internal links in navigation or blog posts
- Allowing redirect chains to build up after site changes
- Submitting sitemaps that contain redirected, blocked, or canonicalised URLs
- Fixing only the page error and not the source of the issue site-wide
Best practices for ongoing monitoring
Crawl error checks should be part of your regular SEO routine, not a one-off task. Search Console works best when you review it consistently and treat it as an early warning system.
Keep your site structure clear so Google can move through important pages easily. Strong internal linking, sensible categories, and clean URL structures make crawl discovery easier for large sites, ecommerce stores, and content-heavy blogs. If your site uses WordPress, pay extra attention to plugins that alter indexing rules, canonical tags, or sitemaps.
It is also worth checking page speed, mobile usability, and Core Web Vitals because poor performance can make crawling and user experience less efficient. For technical checks, Google’s own guidance in the SEO Starter Guide is a reliable reference point. If you are reviewing a wider optimisation plan, Backlink Works also offers a free website SEO audit that can help you spot crawlability and indexing issues in context.
For page-level testing, a tool like PageSpeed Insights can help you identify technical issues that may affect how efficiently Google accesses your pages.
Conclusion
Finding crawl errors in Google Search Console is about more than spotting red flags. It is about understanding why Google is struggling to access certain pages and then fixing the technical or structural problem behind it.
If you review the Pages report, inspect key URLs, check your sitemap, and keep an eye on internal links and site settings, you will be in a much better position to maintain healthy crawlability and support long-term organic traffic growth. Search Console does not replace a full SEO audit, but it is one of the most practical tools for keeping your site visible and search-friendly.
Frequently Asked Questions
Where is the best place to start looking for crawl errors?
Start with the Pages report in Google Search Console. It shows which URLs are indexed, which are excluded, and the reasons Google gives. If a specific page is affected, use URL Inspection to see how Google views that page and whether it can crawl it successfully.
Does a crawl error always mean a page is not indexed?
Not always. Some crawl issues affect discovery or recrawling rather than existing index status. A page may still be indexed for a while even if Google later has trouble crawling it. That is why it is important to check both crawl status and indexing status in Search Console.
What is the difference between a 404 and a server error?
A 404 means the page was not found, usually because it was deleted or the URL is wrong. A server error, often shown as a 5xx issue, means Google could not get a proper response from your server. Server errors are usually more urgent because they may indicate site instability.
Should I fix every crawl issue immediately?
Not necessarily. Some excluded URLs are normal, such as pages intentionally blocked from indexing or redirected after a site update. Focus first on important pages, recurring errors, and issues that affect large sections of the site. Prioritising by impact is usually the most efficient approach.
