How to Fix 403 Errors Viewed from Ahrefs

Finding 403 errors in your Ahrefs Site Audit can be frustrating. These errors mean search engines and users can’t access important pages on your website. The good news? Most 403 errors are simple to fix once you understand what’s causing them. You’ll learn exactly how to identify, diagnose, and resolve these pesky errors that could be hurting your SEO performance right now.

What Are 403 Errors and Why Should You Care?

A 403 error is an HTTP status code that means “Forbidden.” The server understands your request but refuses to authorize it. Think of it like trying to enter a VIP room at a concert. The bouncer knows what you want. But you don’t have the right pass to get in. When Ahrefs crawls your site and encounters 403 errors, it’s telling you that certain pages are blocking access. This creates several problems:

– Search engines can’t index these pages
– You’re losing potential organic traffic
– Users get frustrated when they hit dead ends
– Your site’s crawl budget gets wasted
– Internal link equity stops flowing properly

Every 403 error is a missed opportunity for visibility and engagement.

Common Causes of 403 Errors in Ahrefs

Understanding the root cause makes fixing 403 errors much easier.

Incorrect File Permissions

Your web server uses permission settings to control who can access files. When these are too restrictive, legitimate visitors get blocked. Most files should have 644 permissions. Directories need 755.

IP Blocking or Geographic Restrictions

Some websites block certain IP addresses or entire countries. If you’re blocking Ahrefs’ bot IP addresses, you’ll see 403 errors in your audit.

Hotlink Protection Gone Wrong

Hotlink protection prevents other sites from directly linking to your images. But overly aggressive settings can block legitimate crawlers too.

Plugin or Security Software Conflicts

Security plugins sometimes get too protective. They might mistakenly flag Ahrefs as a threat.

Corrupted .htaccess File

Your .htaccess file controls many access rules. One wrong line of code can trigger widespread 403 errors.

Step-by-Step Guide to Fixing 403 Errors

Ready to clean up those errors? Follow this systematic approach.

Step 1: Verify the Errors in Ahrefs

Log into your Ahrefs account and navigate to Site Audit. Click on the “All issues” report. Filter for “403 page” errors.

Export the list of affected URLs. You’ll need this for testing.

Cross-reference these URLs with your Google Search Console data. Are the same pages showing errors there?

Step 2: Test the URLs Manually

Open an incognito browser window. Try accessing each problematic URL directly.

Do you see the 403 error yourself? If not, the issue might be specific to bots.

Use online HTTP status checkers to verify the response codes. Sometimes the issue is intermittent or location-based.

Step 3: Check Your Robots.txt File

Navigate to yoursite.com/robots.txt in your browser.

Look for any Disallow rules that might be blocking Ahrefs. The Ahrefs bot identifies itself as “AhrefsBot” in its user agent string.

Make sure you’re not accidentally blocking all bots with overly broad rules.

Step 4: Review File and Folder Permissions

Access your hosting control panel or connect via FTP.

Check the permissions on affected files and folders. Files typically need 644 permissions. Folders should be set to 755.

Pay special attention to:
– WordPress wp-content folder
– Image directories
– Download folders
– Any custom directories

Step 5: Examine Your .htaccess File

Download a backup of your .htaccess file first. Always.

Look for problematic rules like:
– Deny from all
– Order deny,allow statements
– IP-based restrictions
– User agent blocking rules

Remove or modify rules that might be causing issues.

Step 6: Whitelist Ahrefs Bot

Add these lines to your .htaccess file to explicitly allow Ahrefs:

# Allow Ahrefs Bot
SetEnvIfNoCase User-Agent “AhrefsBot” good_bot
Order Allow,Deny
Allow from env=good_bot

This ensures Ahrefs can properly crawl your site.

Step 7: Review Security Plugin Settings

Check your security plugin dashboard. Look for bot blocking or firewall settings.

Common culprits include:
– Wordfence
– Sucuri
– iThemes Security
– All In One WP Security

Add Ahrefs to your whitelist. Most security plugins have specific settings for known good bots.

Step 8: Clear Your Cache

Sometimes 403 errors persist due to cached responses.

Clear your:
– Server cache
– CDN cache
– Browser cache
– Plugin caches

This forces fresh responses for all requests.

Preventing Future 403 Errors

Prevention beats troubleshooting every time.

Regular Monitoring: Schedule weekly Ahrefs Site Audits. Catch new 403 errors before they impact your rankings.

Document Your Security Rules: Keep a log of all access restrictions you implement. This makes troubleshooting faster when issues arise.

Test Before Deploying: Always test security changes on a staging site first. One wrong rule can lock out important crawlers.

Use Selective Blocking: Block specific bad bots instead of using blanket restrictions. Maintain a whitelist of legitimate crawlers.

Keep Plugins Updated: Outdated security plugins often have compatibility issues. Regular updates prevent many 403 errors.

When to Seek Professional Help

Some 403 errors require technical expertise.

Contact your hosting provider if:

– Server-level configurations are causing errors
– You can’t access server files
– The errors persist after trying all fixes

Hire a developer when:

– Custom code is triggering 403s
– You’re uncomfortable editing .htaccess files
– Multiple sites on your server show similar issues

Monitoring Your Progress

After implementing fixes, patience is key. Run a new Ahrefs Site Audit after 24-48 hours. The crawler needs time to revisit your pages. Check your organic traffic in Google Analytics. Fixed 403 errors should lead to improved visibility over time. Monitor your server logs. Look for patterns in remaining 403 errors. Set up alerts in Google Search Console. Get notified immediately if new access issues arise.

The Bottom Line

403 errors might seem intimidating at first. But they’re usually simple permission or configuration issues. Taking action on these errors improves your site’s crawlability. Better crawlability means better rankings. Better rankings mean more traffic and conversions. Don’t let 403 errors sabotage your SEO efforts. Use this guide to fix them systematically. Your future self will thank you when those error counts drop to zero in your next Ahrefs audit. Remember, every fixed error is one step closer to maximizing your site’s potential. Start with the quick wins. Build momentum. Soon you’ll have a perfectly crawlable website that search engines love.
