Google Search Console is not just a reporting tool. It is Google’s way of telling you when something has gone wrong with crawling, indexing, or understanding your website. If Google cannot access your pages properly, it cannot rank them properly either.
The good news is that most Google Search Console errors are fixable. Some take minutes. Others require technical support. Either way, the sooner you fix them, the sooner Google can get back to doing its job.
In this guide, we’ll walk through the most common Google Search Console errors, explain what they actually mean and show you how to fix them without pulling your hair out. Let’s start with the issues that stop Google from reaching your pages in the first place.
Why Google Search Console Errors Matter
Think of your website as a high street shop. You can have the best products in town. You can have beautiful window displays. You can even have customers looking for exactly what you sell. But if somebody bricks up the front door, nobody gets inside. Google Search Console errors work in a similar way.
Some errors stop Google from crawling pages. Others prevent indexing. Some create confusion about which version of a page should rank. Left unresolved, these issues can quietly damage your organic visibility.
For UK businesses competing in crowded markets such as legal services, property, healthcare, finance or ecommerce, small technical problems can create a significant disadvantage. That is why regular monitoring matters. Many London SEO agencies reinforce this same message to their clients. Now let’s look at the first group of errors.
Error 1: Server Error 5xx
What it means
A 5xx error tells Google that your server failed to respond correctly when Googlebot attempted to visit a page. In simple terms, Google knocked on the door and nobody answered. These errors commonly include:
- 500 Internal Server Error
- 502 Bad Gateway
- 503 Service Unavailable
Why it happens
Several issues can trigger a 5xx error. Your hosting provider may be experiencing downtime. A plugin update may have broken something. Your server may have run out of resources during a traffic spike. In some cases, poor code or database problems can also cause server failures.
How it affects SEO
If Google repeatedly encounters server errors, it may reduce crawling activity across your website. Important pages can disappear from the index. Rankings may drop over time.
How to fix it
- Start by checking whether the problem still exists. Use tools such as server logs, uptime monitoring software, or your hosting dashboard.
- If the error appeared after a recent website update, roll back the change and test again.
- Speak with your hosting provider if necessary. A good host should help identify server-related problems quickly.
- Once fixed, request indexing through Google Search Console so Google can revisit the affected pages.
Error 2: Redirect Errors
What it means
Redirects help users and search engines reach the correct page when URLs change. However, not all redirects behave as expected. Google Search Console reports redirect errors when something interrupts the journey from one URL to another.
Common causes
- Redirect loops are one of the biggest culprits. Imagine asking somebody for directions to Manchester and being sent in a circle around Birmingham all afternoon. Eventually you would give up. Googlebot does exactly the same.
- Long redirect chains can also create problems. If a URL redirects multiple times before reaching the final destination, Google may stop following the chain.
- Broken URLs inside redirect paths can trigger errors too.
How it affects SEO
Redirect errors waste crawl budget and slow down indexing. Users may also encounter frustrating experiences if pages fail to load correctly.
How to fix it
- Run a website crawl using tools such as Screaming Frog.
- Identify the original URL and final destination.
- Remove unnecessary redirect steps wherever possible.
- A single redirect from the old URL to the new URL is usually the best approach.
- Keep redirect paths short, clean, and logical.
Error 3: Not Found 404
What it means
A 404 error appears when Google attempts to access a page that no longer exists. This is one of the most common Search Console errors. Not every 404 is bad. If you intentionally deleted a page and it no longer serves a purpose, a 404 may be perfectly acceptable. Problems arise when valuable pages disappear unexpectedly.
Why it happens
The most common causes include:
- Deleted pages
- Incorrect URLs
- Website migrations
- Broken internal links
- Missing redirects
Many businesses redesign their websites and forget to redirect old URLs. That is like moving house and forgetting to tell anyone your new address.
How it affects SEO
Google cannot rank a page that no longer exists. If important backlinks point towards a deleted page, valuable authority may also be lost. Users landing on broken pages often leave immediately.
How to fix it
- Identify whether the missing page should still exist.
- If the content has moved, create a 301 redirect.
- If the page has a suitable replacement, redirect users there.
- Update internal links pointing to outdated URLs.
- Review your XML sitemap and remove pages that no longer exist.
Error 4: Soft 404 Errors
What it means
A soft 404 is slightly more confusing. The page technically exists. The server returns a successful response. But Google believes the page provides little or no value. As far as Google is concerned, the page might as well be missing.
Common causes
- Thin content is a frequent reason.
- Empty category pages often trigger soft 404 warnings.
- Poorly configured search result pages can create the same issue.
- Some websites accidentally display ‘page not found’ messages while still returning a successful status code.
- That sends mixed signals to Google.
How it affects SEO
Soft 404 pages rarely rank well. They can waste crawl resources and dilute overall website quality signals.
How to fix it
Review the affected page carefully. Ask yourself a simple question. Would a visitor genuinely find this page useful? If the answer is no, improve the content or remove the page entirely. Add unique information, supporting content, images, FAQs or useful resources. If the page no longer serves a purpose, redirect it to a relevant alternative.
Error 5: Blocked by Robots.txt
What it means
Your robots.txt file tells search engines which areas of your website they can and cannot access.
Sometimes important pages become blocked accidentally.
Google then reports a robots.txt issue inside Search Console.
Why it happens
Developers often block pages during website development.
Later, those restrictions remain in place after launch.
A single line inside robots.txt can prevent Google from crawling entire sections of your website.
It happens more often than many business owners realise.
How it affects SEO
Google cannot properly crawl blocked pages. If important content sits behind a robots.txt restriction, rankings can suffer. In some cases, entire website sections may disappear from search results.
How to fix it
- Open your robots.txt file.
- Check whether important pages or directories are blocked.
- Remove unnecessary disallow rules.
- After updating the file, test it using Google Search Console tools and request a recrawl.
- A five-minute review can sometimes uncover problems that have been quietly limiting performance for months.
Fixing Indexing Problems That Stop Rankings
Some Google Search Console errors are easy to spot. Others quietly damage your SEO behind the scenes. The most frustrating issues often involve indexing. Your page exists. The content is live. Internal links point to it. Yet Google refuses to show it in search results. That is where many businesses lose valuable organic traffic.
Let’s look at the indexing issues that commonly appear in Google Search Console and what you can do about them.
Crawled But Not Indexed
This is one of the most common and misunderstood reports in Search Console. Google has successfully visited the page. It has read the content. It has analysed the page. Then it decided not to add the page to its index. In simple terms, Google looked at the page and chose to leave it on the bench. Several factors can cause this.
- The content may be too thin.
- The page may duplicate information already available elsewhere on the site.
- The page may provide little value compared to competing pages already indexed.
- In some cases, the content simply does not satisfy search intent.
How to fix it
Start by reviewing the page honestly. Ask yourself:
- Does this page solve a real problem?
- Is it better than competing pages?
- Does it contain original insights?
- Is it comprehensive enough?
Improve the content where necessary. Add useful examples. Expand shallow sections. Include expert commentary. Add supporting media such as images, charts, videos or downloadable resources. Internal links can also help.
If a page has no internal authority flowing towards it, Google may treat it as unimportant. Link to the page from relevant service pages, blogs and navigation areas where appropriate. Sometimes a few strong internal links can make all the difference.
Discovered But Not Indexed
This error differs from the previous one. Google knows the page exists. However, it has not crawled it yet. Think of it as your page sitting in Google’s queue waiting for attention.
Common causes include:
- Weak internal linking
- Large websites with crawl budget issues
- Newly published content
- Poor website architecture
- Server performance problems
How to fix it
- Make sure the page appears in your XML sitemap.
- Add internal links from relevant pages.
- Check whether your site loads quickly.
- A slow website can discourage frequent crawling.
You can also manually request indexing through URL Inspection. However, this should not become your long-term strategy. The goal is to build a website structure that naturally encourages Google to crawl important pages.
Duplicate Without User Selected Canonical
Google dislikes confusion. When multiple pages contain very similar content, Google must decide which version deserves indexing. If you have not specified a preferred version, Search Console may report:
‘Duplicate without user-selected canonical.’
This often happens with:
- URL parameters
- Product filters
- Printer-friendly versions
- Duplicate service pages
- CMS-generated duplicates
How to fix it
- Choose the page you want Google to index.
- Add a canonical tag pointing to that preferred URL.
- Make sure duplicate versions also point towards the chosen canonical page.
- Review internal links as well.
- Internal links should support the preferred version consistently.
- Mixed signals create unnecessary confusion.
Google Chose A Different Canonical
Sometimes website owners select a canonical URL. Google ignores it. Search Console then reports:
‘Duplicate, Google chose a different canonical than user.’
This means Google disagrees with your choice. That usually happens because Google’s signals point elsewhere. For example:
- Internal links favour another page
- Duplicate pages are nearly identical
- The selected canonical page appears weaker
- External backlinks point elsewhere
How to fix it
- Strengthen the page you want indexed.
- Improve internal linking.
- Ensure canonical tags are correctly implemented.
- Review sitemap entries.
- Remove conflicting signals wherever possible.
- Think of canonicalisation as voting.
- Every signal should vote for the same page.
- When the votes split, Google makes its own decision.
Alternate Page With Proper Canonical Tag
This report often causes unnecessary panic. In many cases, it is not actually a problem. Google has found a duplicate page and recognised the canonical tag correctly. The page has been excluded intentionally. That is exactly what should happen.
When to leave it alone
Leave it untouched if:
- The page is genuinely duplicated
- Canonical tags are correct
- The preferred page is indexed
Many SEO teams waste time trying to ‘fix’ reports that are already functioning perfectly. Not every warning requires action. Sometimes the smartest move is simply to move on.
Indexed Though Blocked By Robots.txt
This error sounds strange because it is strange. The page is blocked from crawling. Yet Google has indexed it. How? Usually because Google discovered the URL through links from other websites.
Google may know the page exists without actually crawling it. As a result, it can still appear in search results.
Why this matters
- Users may see incomplete listings.
- Meta descriptions may not appear.
- Google may have limited understanding of page content.
How to fix it
Decide whether the page should be indexed. If yes:
- Remove the robots.txt block.
- Allow Google to crawl the page fully.
If no: Use a noindex directive instead.
Remember one important rule. Google cannot see a noindex tag on a blocked page because it cannot crawl the page. That catches many site owners out. It is a classic case of being caught between a rock and a hard place.
HTTPS Problems
Website security remains a ranking consideration. Google expects modern websites to use HTTPS. Most UK businesses already do. However, Search Console occasionally reports HTTPS-related issues.
Common causes include:
- Mixed content warnings
- HTTP pages still accessible
- Incorrect redirects
- SSL certificate problems
How to fix it
- Ensure all pages redirect from HTTP to HTTPS.
- Update internal links.
- Replace hard-coded HTTP assets.
- Check image URLs, scripts and stylesheets.
- Review your SSL certificate regularly.
A secure website protects both rankings and users. That is a win-win situation.
Manual Actions
A manual action is one of the most serious alerts in Google Search Console. Unlike algorithm updates, manual actions involve a human reviewer at Google. Someone has examined the website and found a guideline violation.
Common triggers include:
- Unnatural backlinks
- Thin content
- Hidden text
- Cloaking
- Spam content
- Structured data abuse
If a manual action appears, organic visibility can drop dramatically.
How to fix it
- Read Google’s explanation carefully.
- Identify the root cause.
- Fix the issue completely.
- Document every action taken.
- Then submit a reconsideration request.
Transparency matters here. Google wants evidence that the issue has genuinely been resolved. Half measures rarely work.
Security Issues
Security warnings deserve immediate attention. If Google believes a website may harm users, search visibility can disappear quickly.
Common issues include:
- Malware infections
- Hacked pages
- Phishing content
- Spam injections
How to fix it
- Run a full security audit.
- Remove malicious code.
- Update passwords.
- Patch vulnerable plugins.
- Strengthen server security.
- After cleaning the website, request a security review through Search Console.
Preventing Search Console Errors
Fixing errors is good. Preventing them is better. The strongest SEO strategies focus on prevention rather than firefighting. Here are several practical habits that reduce technical SEO issues.
Run regular audits
Review your website monthly. Spot small issues before they become major problems.
Monitor Search Console weekly
Do not wait until traffic drops. Search Console often provides early warning signs.
Keep sitemaps updated
New pages should appear quickly. Deleted pages should disappear promptly.
Review redirects regularly
Websites evolve. Redirect chains accumulate over time. Clean them before they become problematic.
Strengthen internal linking
Internal links guide both users and search engines. A strong structure improves crawling efficiency.
Prioritise page experience
Fast websites perform better. Users stay longer. Google crawls more efficiently. Everyone benefits. For businesses seeking expert support, agencies like Prox Digital Agency offer practical technical SEO guidance that helps prevent these errors from occurring in the first place
Final Thoughts
Google Search Console is far more than a reporting tool. It is a direct communication channel between your website and Google. Every error tells a story. Some stories reveal technical mistakes. Others expose content weaknesses or structural problems.
The businesses that win in search are usually not the ones with the biggest budgets. They are the ones that pay attention. They monitor their websites consistently. They fix problems quickly. They remove technical barriers before competitors even notice them.
If your rankings have stalled, your traffic has dipped, or your pages are struggling to gain visibility, Google Search Console is often the first place worth investigating. Because sometimes the biggest SEO opportunities are hiding in plain sight.
