15 Most Common Google Search Console Errors and Warnings (2026)

Google Search Console errors and warnings are notifications indicating technical issues, indexation problems, or security concerns preventing pages from appearing in search results or harming search performance.

At HiAgency, we resolve Google Search Console issues for Australian businesses including indexation errors, mobile usability problems, Core Web Vitals failures, and security warnings that impact organic visibility and Technical SEO performance.

This guide covers the 15 most common Google Search Console errors and warnings, explaining what each means and how to fix them.

1. Server Error (5XX)

What it means: Your server returned 500-series error codes when Google tried to crawl pages, preventing access entirely.

Impact: Severe – affected pages can’t be crawled or indexed. Existing indexed pages may be removed if errors persist.

Common causes:

• Server overload from traffic spikes
• Database connection failures
• Server configuration errors
• Hosting resource limits exceeded
• Plugin or script crashes (WordPress sites)

How to fix:

• Check server logs identifying specific error causes
• Increase server resources if hitting capacity limits
• Fix database connection issues
• Disable problematic plugins or scripts
• Contact hosting provider for persistent server problems
• Implement CDN reducing server load

Once fixed, use “Request Indexing” in URL Inspection tool for critical pages.

2. Submitted URL Not Found (404)

What it means: URLs submitted in your sitemap return 404 errors when Google attempts to crawl them.

Impact: High – pages returning 404s won’t be indexed. If previously indexed pages start returning 404s, they’ll be removed from search results.

Common causes:

• Deleted pages still listed in sitemaps
• Incorrect URLs in sitemap (typos, wrong paths)
• Pages moved without proper redirects
• Permalink structure changes

How to fix:

• Remove deleted URLs from XML sitemaps
• Implement 301 redirects from old URLs to new locations
• Fix typos or incorrect URLs in sitemaps
• Regenerate sitemaps reflecting current site structure
• For intentionally deleted pages, allow 404 status (don’t try to fix)

3. Redirect Error

What it means: Redirect chains, loops, or incorrect redirect implementations prevent Google from reaching final destinations.

Impact: High – pages with redirect errors can’t be crawled properly. Redirect chains waste crawl budget and dilute ranking authority.

Common causes:

• Redirect chains: URL A → URL B → URL C
• Redirect loops: URL A → URL B → URL A
• Redirects to URLs that also redirect
• Incorrect redirect configurations

How to fix:

• Audit redirects using Screaming Frog or similar tools
• Update redirects pointing directly to final destinations
• Fix redirect loops immediately
• Consolidate redirect chains into single-step redirects
• Test redirects after implementation ensuring proper function

4. Blocked by Robots.txt

What it means: Your robots.txt file blocks Googlebot from crawling specific URLs or sections.

Impact: Severe – blocked pages can’t be crawled or indexed. Critical pages accidentally blocked disappear from search results.

Common causes:

• Accidentally blocking important pages or directories
• Staging site robots.txt copied to production
• Overly aggressive disallow rules
• Blocking CSS, JavaScript, or images needed for rendering

How to fix:

• Review robots.txt file (yoursite.com/robots.txt)
• Remove disallow rules blocking important content
• Use specific paths in disallow rules (avoid blocking entire directories unintentionally)
• Test robots.txt using Search Console’s robots.txt tester
• Ensure CSS, JavaScript, and images aren’t blocked

5. Blocked by Meta Robots Noindex Tag

What it means: Pages include noindex meta tags explicitly telling Google not to index them.

Impact: High – noindexed pages won’t appear in search results. Accidentally noindexing important pages removes them from indexation.

Common causes:

• Development noindex tags left in production
• SEO plugins automatically adding noindex to certain page types
• Template-level noindex affecting multiple pages
• Intentional noindex on pages that should be indexed

How to fix:

• Search page source for “noindex” in meta robots tags
• Remove noindex from pages you want indexed
• Check SEO plugin settings (WordPress: Yoast, Rank Math)
• Review template files for site-wide noindex implementations
• Request indexing after removing noindex tags

6. Soft 404 Error

What it means: Pages return 200 success codes but display “not found” content, confusing Google about whether pages exist.

Impact: Medium – Google may remove soft 404 pages from index despite returning success codes.

Common causes:

• Custom 404 pages returning 200 status instead of 404
• Pages with minimal content appearing empty
• “No results” pages for searches or filters
• Deleted content displaying generic “content unavailable” messages

How to fix:

• Configure 404 pages to return proper 404 status codes
• Add substantial content to thin pages
• Implement proper 301 redirects for deleted pages
• Use 404 status for truly missing content

7. Crawled – Currently Not Indexed

What it means: Google successfully crawled pages but determined they don’t merit indexing due to quality issues.

Impact: High – pages remain invisible in search results despite Google accessing them.

Common causes:

• Thin content (under 300 words with minimal value)
• Duplicate or near-duplicate content
• Low page quality or authority
• Poor technical performance

How to fix:

• Significantly expand content (add 500-1,000 words with genuine value)
• Differentiate duplicate content or consolidate with canonicals
• Build internal and external links to pages
• Improve page speed and Core Web Vitals
• Add unique elements (images, videos, data, examples)

8. Discovered – Currently Not Indexed

What it means: Google found URLs through crawling or sitemaps but hasn’t prioritized crawling them yet, or crawled minimally.

Impact: Medium – pages aren’t indexed but may be lower priority rather than quality issues.

Common causes:

• Limited crawl budget on large sites
• Low page importance signals
• Pages with no internal links (orphan pages)
• Recently created pages not yet crawled

How to fix:

• Add internal links from important pages
• Improve content quality making pages worth crawling
• Optimize crawl budget by blocking low-value sections
• Request indexing via URL Inspection tool
• Submit/resubmit XML sitemap

9. Page With Redirect

What it means: Submitted URLs in sitemaps redirect to other locations instead of serving content directly.

Impact: Medium – redirecting pages won’t be indexed. Google indexes redirect destinations instead.

Common causes:

• Old URLs remaining in sitemaps after redirects implemented
• HTTP URLs in sitemaps when site uses HTTPS
• Sitemap automation including redirected URLs

How to fix:

• Update sitemaps to include only final destination URLs
• Remove redirecting URLs from sitemaps
• Ensure sitemaps use HTTPS URLs if site is HTTPS
• Regenerate sitemaps reflecting current site structure

10. Duplicate Without User-Selected Canonical

What it means: Google found duplicate pages but you didn’t specify canonical preferences, forcing Google to choose.

Impact: Medium – Google may index non-preferred versions without canonical guidance.

Common causes:

• URL variations (www/non-www, trailing slashes, parameters)
• Pagination without canonicals
• Similar content across pages
• Missing canonical tag implementation

How to fix:

• Implement canonical tags on all pages
• Use self-referencing canonicals on preferred versions
• Canonicalize duplicate variations to preferred URLs
• Use 301 redirects for true duplicates

11. Mobile Usability Issues

What it means: Pages have problems affecting mobile user experience – small text, elements too close, viewport issues.

Impact: Medium – mobile usability problems harm mobile rankings with mobile-first indexing.

Common issues:

• Text too small to read (under 16px)
• Clickable elements too close together (under 48px spacing)
• Content wider than screen requiring horizontal scrolling
• Viewport not configured properly

How to fix:

• Implement responsive design with mobile-first approach
• Use minimum 16px font sizes for body text
• Space interactive elements at least 48px apart
• Add viewport meta tag: <meta name=”viewport” content=”width=device-width, initial-scale=1″>
• Test on actual mobile devices
• Use Google’s Mobile-Friendly Test tool

12. Core Web Vitals Issues

What it means: Pages fail Google’s Core Web Vitals thresholds for loading speed, interactivity, or visual stability.

Impact: Medium – poor Core Web Vitals harm rankings and user experience.

Three metrics:

• LCP (Largest Contentful Paint): Target under 2.5 seconds
• INP (Interaction to Next Paint): Target under 200 milliseconds
• CLS (Cumulative Layout Shift): Target under 0.1

How to fix:

• LCP: Optimize images, minimize render-blocking resources, improve server response times, use CDN
• INP: Minimize JavaScript execution, break up long tasks, optimize event handlers
• CLS: Add width/height attributes to images, avoid injecting content above existing content, use CSS transform for animations

Monitor improvements using PageSpeed Insights and Search Console Core Web Vitals report.

13. Security Issues Warning

What it means: Google detected security problems – hacked content, malware, phishing, or deceptive practices.

Impact: Severe – security warnings display in search results, drastically reducing clicks. Severe cases result in complete removal from search results.

Common security issues:

• Hacked site with malicious code injection
• Malware distribution
• Phishing pages
• Deceptive content or unwanted software

How to fix:

• Identify and remove all malicious code immediately
• Change all passwords (hosting, CMS, database, FTP)
• Update all software (CMS, plugins, themes)
• Review Security Issues report in Search Console for specific problems
• Request security review after cleaning site
• Implement security measures preventing reinfection (firewall, security plugins)

14. Manual Actions

What it means: Google’s human reviewers determined your site violates Webmaster Guidelines, applying manual penalties.

Impact: Severe – manual actions significantly harm rankings or remove pages/sites from search results entirely.

Common manual actions:

• Unnatural links to/from your site
• Thin content with little or no added value
• Cloaking or sneaky redirects
• Pure spam
• User-generated spam

How to fix:

• Review Manual Actions report in Search Console for specific violations
• Fix all issues completely (remove/disavow bad links, improve content, remove spam)
• Document fixes thoroughly
• Submit reconsideration request explaining what was wrong and how you fixed it
• Wait for Google review (can take weeks)

15. AMP Issues

What it means: Accelerated Mobile Pages have validation errors preventing proper display or indexation.

Impact: Medium – AMP errors prevent pages from appearing in AMP-specific features and mobile search enhancements.

Common AMP issues:

• Invalid AMP HTML
• Disallowed HTML tags or attributes
• Missing required markup
• CSS too large (over 75KB limit)
• Image dimension issues

How to fix:

• Use AMP Validator tool identifying specific errors
• Review AMP documentation for correct implementation
• Remove disallowed tags and attributes
• Reduce CSS size under 75KB limit
• Add required markup elements
• Test using Google’s AMP testing tool

How to Monitor Google Search Console Issues?

Regular monitoring prevents minor issues from becoming major problems harming traffic and rankings.

Monitoring routine:

• Weekly checks: Review Overview dashboard for new errors or warnings. Check Coverage report for indexation changes.
• Monthly reviews: Deep dive into Core Web Vitals, Mobile Usability, and Enhancement reports. Analyze trends in crawl stats.
• Set up email alerts: Configure Search Console to email when critical issues detected.
• Track metrics over time: Monitor indexed page counts, coverage errors, Core Web Vitals performance tracking improvements or degradations.

Address errors immediately (server errors, security issues, critical indexation blocks) and warnings within 1-2 weeks (performance issues, mobile usability, lower-priority coverage problems).

Should You Fix All Errors and Warnings?

Not all reported issues require fixes. Prioritize based on impact and page importance.

High priority (fix immediately):

• Server errors affecting important pages
• Security issues
• Manual actions
• Important pages blocked by robots.txt or noindex
• Core Web Vitals failures on high-traffic pages

Medium priority (fix within weeks):

• Mobile usability issues
• Crawled but not indexed pages you want indexed
• Redirect errors
• Duplicate content without canonicals

Low priority or acceptable:

• 404 errors for intentionally deleted pages
• Soft 404s for search results or filters
• Pages you don’t want indexed showing excluded status
• Old pagination pages showing discovered but not indexed

Focus optimization efforts on high-value pages generating traffic and conversions rather than fixing every minor issue across low-value pages.

Should You DIY or Hire Specialists?

Small sites with basic errors (missing meta tags, simple mobile issues, a few 404s) can often fix problems using CMS plugins or following Google’s help documentation.

Hire specialists when facing:

• Large-scale technical issues affecting hundreds of pages
• Server errors requiring hosting or development expertise
• Security issues or manual actions
• Core Web Vitals optimization requiring performance expertise
• Complex canonicalization or redirect problems
• Persistent issues despite attempted fixes
• Critical pages remaining unindexed affecting revenue
