Crawl Errors

If you have opened Google Search Console and seen crawl errors, it is completely normal to feel concerned. When leads, sales, or enquiries depend on your website being visible, even a small warning can look bigger than it really is, but most crawl errors can be understood and fixed with a calm, step by step approach.

Crawl errors happen when Googlebot, or another search engine crawler, cannot properly access a page, file, or section of your website. If important pages cannot be crawled, Google may struggle to discover them, refresh them, or understand whether they should appear in search results, which can affect visibility, organic traffic, and online performance.

The first thing to know is that crawling and indexing are not the same. Crawling is when Googlebot fetches a URL, while indexing is when Google decides whether that page should be stored and shown in search results, so a page can be crawled successfully and still remain unindexed.

Finding the real cause usually means checking Google Search Console, inspecting individual URLs, reviewing your XML sitemap, looking at HTTP status codes, and checking robots.txt or noindex settings. HTTP status codes are server replies, such as 200 for a working page, 404 for a missing page, or 500 for a server problem, while server logs can also show exactly how Googlebot is interacting with larger or more complex sites.

What Are Website Crawl Errors?

Website crawl errors are problems that stop a search engine crawler from reaching, reading, or processing a URL as expected. These issues can affect one page, a group of pages, or your whole site if the problem is linked to hosting, DNS, robots.txt, or server availability.

DNS works like the internet's address book, helping browsers and crawlers find the right server for your domain. A clear example of a crawl error is a service page returning a 500 server error instead of loading normally, or an important product page being blocked in robots.txt, which tells crawlers not to access it.

Have you recently changed your website structure, redesigned key pages, moved hosting, or updated your CMS? Crawl problems often show up after website migrations, redesigns, CMS changes, plugin updates, hosting issues, or changes to URL structures, and they can also build up slowly when old pages are deleted or sitemaps are not kept clean.

Crawling Versus Indexing

Crawling is the discovery and fetching stage. Googlebot follows links, reads sitemaps, checks redirects, and requests pages from your server, and if the crawler can access the page and receive a useful response, the crawling stage has usually worked.

Indexing comes later. Google looks at the content, canonical tags, duplicate signals, noindex directives, quality, relevance, and other factors before deciding whether the page should appear in search, while canonical tags tell search engines which version of a similar or duplicate page you prefer.

This distinction matters because the right fix depends on the problem. A blocked page needs an access fix, while a duplicate page may need better canonicalisation, and if you want a wider SEO foundation before tackling deeper technical issues, C2 Marketing's SEO support can help connect crawlability, content quality, and ranking performance.

How To Find Crawl Errors In Google Search Console

The best starting point is Google Search Console because it shows how Google sees your website. The old standalone Crawl Errors report is no longer the main workflow, so you should use the Page indexing report, Crawl Stats report, and URL Inspection tool to spot patterns and investigate individual URLs.

Open Search Console and go to Indexing, then Pages. Review the listed reasons for pages that are not indexed, but remember that not every reason is a crawl failure, then look for issues such as server error, redirect error, not found, blocked by robots.txt, or soft 404.

Next, go to Settings, then Crawl Stats. This report helps you review Googlebot activity over time, including total crawl requests, response codes, file types, host status, and periods where availability may have dropped, and Google provides detailed Google's crawling error guidance covering availability, server responses, sitemaps, and robots.txt.

Use URL Inspection For Individual Pages

The URL Inspection tool is essential when you need to understand one page properly. Enter the full URL exactly as it appears in the browser, including the correct protocol, hostname, and path, because a small difference, such as using http instead of https or including the wrong trailing slash, can change the result.

Look at the page status, last crawl date, crawl allowed status, canonical information, and any listed problems. Then select Test Live URL to check whether the issue is still happening right now, as Search Console can show historical data even after you have fixed the live problem.

Once a priority page is fixed, you can use Request indexing for that URL. For grouped issues in the Page indexing report, use Validate Fix where available, but remember that Google still needs time to recrawl and process the page.

How To Find And Fix Crawl Errors

The fastest way to fix crawl errors is to identify the response or access problem first, then apply the correct solution. Guessing can cause more harm than good, especially if you redirect pages unnecessarily or unblock URLs that were meant to stay private.

Start with the URLs that matter most to your business, such as money pages, lead generation pages, high traffic content, and pages with backlinks. Once the priority pages are safe, you can work through lower value errors and clean up the wider site structure.

404 And 410 Errors

A 404 means the page was not found, while a 410 means the page is gone. These are not always bad, because if a page has been permanently removed and there is no useful replacement, a proper 404 or 410 can be the right response.

You should fix 404 errors when important pages have disappeared by mistake, internal links point to broken URLs, or sitemap URLs return not found responses. If there is a close replacement, add a 301 redirect to the relevant live page, but avoid redirecting users to the homepage just to remove the error.

For WordPress users, broken URLs are especially common after slug edits, deleted posts, or plugin changes. C2 Marketing has a helpful article on how to handle 404 errors if you need a more focused walkthrough.

5xx Server Errors

Server errors such as 500, 502, 503, and 504 mean the crawler requested the page, but the server could not respond properly. These errors can be serious if they affect important pages or appear across large parts of the site, and Google may reduce crawling if the server repeatedly fails.

Check your hosting, server resources, database health, CDN settings, firewall rules, and recent code or plugin updates. A CDN is a network that helps serve your website faster by storing files closer to users, and if the site is temporarily unavailable because of maintenance or overload, a correct 503 response is better than serving broken content.

DNS And Network Errors

DNS errors happen when Googlebot cannot resolve your domain or connect to the right server. These issues often happen because of nameserver problems, incorrect DNS records, firewall blocks, CDN failures, or connection timeouts, and they are often critical because they can affect the whole site.

Check your A records, CNAME records, nameserver settings, and hosting status. You should also review any security tools that might block bots too aggressively, because if Googlebot is being mistaken for suspicious traffic, your firewall or CDN configuration may need adjusting.

Robots.txt Blocks

Robots.txt tells crawlers which areas of your site they should not access. It is useful, but a small mistake can block important pages, folders, scripts, images, or CSS files, which may stop Googlebot from understanding the page properly.

Open your robots.txt file directly by visiting yourdomain.com/robots.txt. Look for Disallow rules affecting important pages or site sections, then remove accidental blocks while keeping intentional rules for low value areas such as internal search results, admin paths, or duplicate filter pages where appropriate.

Robots.txt is different from noindex. Robots.txt controls crawling, while noindex controls whether a crawled page should be indexed, so if you block a page in robots.txt, Google may not be able to crawl it and see the noindex instruction.

Redirect Chains And Loops

A redirect chain happens when one URL redirects to another, which then redirects again before reaching the final page. A redirect loop happens when URLs redirect in a circle and never reach a final destination, and both can waste crawl budget and create poor user experiences.

Crawl budget means the time and attention Google spends crawling your site. Fix redirect chains by pointing old URLs directly to the final destination, updating internal links so they use the final live URL, and removing redirected URLs from your XML sitemap.

Soft 404 Errors

A soft 404 occurs when a page returns a successful 200 response but behaves like a missing or useless page. This often happens with empty category pages, thin search result pages, broken product pages, or custom error pages that do not return the correct status code.

If the content is genuinely gone, return a real 404 or 410. If the page should remain live, improve the content so it offers a clear purpose and useful information, especially on ecommerce websites where some out of stock products should stay live while others may need redirects or removal.

Check Your XML Sitemap And Internal Links

Your XML sitemap should help Google discover the URLs you actually want crawled and indexed. It should include canonical, indexable pages that return a 200 status and matter to your website, not broken URLs, redirected URLs, blocked pages, noindex pages, duplicates, or low value parameter variations.

Submit your sitemap in Search Console and compare submitted URLs with indexed URLs. Some difference is normal, but large gaps can point to quality, crawlability, or canonical problems, and if you are unsure how sitemap submission works, this article on submitting an XML sitemap explains the process clearly.

Internal links matter just as much because search engines use links to discover pages and understand site structure. Check your navigation, footer, breadcrumbs, related content blocks, and in content links for broken or outdated URLs, and make sure important pages are not hidden with no meaningful links pointing to them.

Prioritise The Errors That Matter Most

Not every crawl issue deserves the same level of attention. A server error on your main service page is far more important than a deliberate 404 on an old event page, so good prioritisation helps you spend time where it will protect traffic, leads, and revenue.

Fix critical problems first, including widespread 5xx errors, DNS failures, accidental robots.txt blocks, redirect loops, unavailable high value pages, and sitemap URLs that cannot be crawled. These issues can stop Google from accessing important content and should be treated quickly.

Next, deal with broken internal links, redirect chains, incorrect canonicals, orphan pages, and crawl traps caused by filters or URL parameters. These may not always cause immediate traffic drops, but they make crawling less efficient, and for larger websites, this article on crawl budget explains how Googlebot spends its time across your site.

Some issues can simply be monitored, including deliberate 404s, correctly noindexed pages, duplicate URLs consolidated with canonicals, and historical errors that now pass live testing. The key is to understand intent rather than chasing error counts blindly.

Quick Priority Guide

• Urgent. Widespread server errors, DNS failures, accidental robots.txt blocks, redirect loops, and broken high value pages.
• Moderate. Broken internal links, redirect chains, sitemap errors, incorrect canonicals, orphan pages, and crawl traps.
• Low concern. Deliberate 404s, correctly noindexed pages, duplicate URLs handled with canonicals, and old errors that now pass live testing.

Validate Your Fixes Properly

After making changes, always test before assuming the issue is solved. Use URL Inspection and Test Live URL for individual pages, then confirm the page returns the correct HTTP status, is not blocked by robots.txt, does not carry an unwanted noindex directive, and points to the right canonical URL.

Check that the page is included in the sitemap only if it should be indexed. Update internal links so users and crawlers reach the correct version directly, and if the issue affected a group of URLs, return to the Page indexing report and start validation where the option is available.

Search Console may take time to reflect the fix because Google has to recrawl the URL and process the new signals. For important pages, requesting indexing can help prompt a revisit, but it does not guarantee immediate indexing, so keep an eye on Crawl Stats, Page indexing, and organic performance over the following days and weeks.

Crawl Error Troubleshooting Checklist

• Check the correct Search Console property.
• Review Indexing, then Pages.
• Open Settings, then Crawl Stats.
• Inspect affected URL examples.
• Use Test Live URL for current status.
• Check HTTP status codes.
• Review robots.txt rules.
• Check noindex tags and headers.
• Review canonical tags.
• Repair broken internal links.
• Clean and resubmit the XML sitemap.
• Check server logs if errors are unclear.
• Request indexing or validate the fix when ready.

Final Thoughts

Crawl errors can look intimidating at first, especially when traffic or leads are important to your business. The process becomes much easier when you separate access problems from indexing decisions, then start with Google Search Console, inspect real examples, test live URLs, and focus first on the pages that matter most.

The aim is not to remove every warning from every report. The aim is to make sure search engines can access, understand, and refresh your most valuable pages without unnecessary friction, giving your SEO a stronger technical foundation to build on.

If you are unsure which crawl errors matter most, or you want a technical SEO review before making changes, C2 Marketing can help you find the cause, plan the fix, and protect your organic visibility.

Frequently Asked Questions

Does Every Crawl Error Hurt Rankings?

No, the impact depends on the URL, how important it is, and how long the issue lasts. A broken high value page is much more serious than an old page that was removed on purpose.

Should Every 404 Error Be Redirected?

No, only redirect a 404 when there is a close and useful replacement. If the page is gone and there is no relevant alternative, a proper 404 or 410 is often fine.

How Long Does Google Take To Recrawl A Fixed Page?

It varies from a few days to several weeks depending on the site and URL importance. Search Console may continue showing the old issue until Google recrawls and updates its data.

Is Robots.txt The Same As Noindex?

No, robots.txt controls whether crawlers can access a URL, while noindex tells search engines not to index a page. Google usually needs to crawl a page to see a noindex directive.

Can A Page Be Crawled But Not Indexed?

Yes, crawling and indexing are separate stages. A page may be crawled successfully but not indexed because of quality, duplication, canonicals, noindex settings, or other signals.
