How to fix 'Blocked by Robots.txt' issue in Google Search Console

If you're managing a website, encountering the "Blocked by Robots.txt" issue in Google Search Console can be frustrating. This error prevents search engines from crawling specific pages on your site, potentially harming your site's SEO performance. In this detailed guide, we’ll explain what this issue means, why it happens, and how you can fix it step-by-step.

What Does 'Blocked by Robots.txt' Mean?

When Google Search Console reports that a page is blocked by robots.txt, it means that the page has been disallowed from being crawled by search engine bots. This happens due to the directives specified in your website’s robots.txt file.

The robots.txt file is a text file that tells search engines which pages or files they can or cannot crawl. While it’s a powerful tool, improper configuration can block essential pages from being indexed by Google, affecting your site's visibility in search results.

Why Does 'Blocked by Robots.txt' Happen?

Here are the most common reasons for this issue:

1. Misconfigured Robots.txt File: A disallow rule might unintentionally block important pages.
2. Temporary Blocking During Development: Developers often block bots during site development but forget to remove the restrictions after launch.
3. CMS Settings: Platforms like WordPress or Shopify may auto-generate restrictive robots.txt rules.
4. Server Errors: A misconfigured server might restrict bots from accessing your site.
5. Dynamic Pages: Some dynamically generated URLs might be blocked by default.

How to Fix 'Blocked by Robots.txt' Issue: Step-by-Step Guide

Step 1: Understand Your Robots.txt File

The robots.txt file is located at:

https://yourwebsite.com/robots.txt  

To view it:

• Open your browser.
• Enter the URL above (replace yourwebsite.com with your domain).

Example of a Robots.txt File:

User-agent: *  
Disallow: /admin/  
Disallow: /private/  

• User-agent specifies which bots the rules apply to.
• Disallow blocks access to specified directories or pages.

Step 2: Check for Errors in the Robots.txt File

Look for any disallow rules blocking the affected pages. For example:

Disallow: /important-page/  

If this page is essential for SEO, you’ll need to remove or modify the rule.

Step 3: Update the Robots.txt File

To fix the issue:

1. Access Your Robots.txt File

   • If you're using a CMS like WordPress, use an SEO plugin like Yoast SEO or Rank Math to edit the robots.txt file.
   • For custom websites, access the file via your hosting control panel or FTP.

2. Modify or Remove the Blocking Rule
   For example, if the blocked page is /about-us/, change:

   Disallow: /about-us/  
   

   To:

   Allow: /about-us/  
   

3. Save and Upload the Updated File

   • Save your changes and upload the updated file to your site’s root directory.

Step 4: Test Your Robots.txt File

Use Google’s Robots.txt Tester tool:

• Go to Robots.txt Tester.
• Enter your URL and check if the page is accessible.

Alternative Fixes: If Robots.txt Is Not the Issue

If your robots.txt file isn’t blocking the page, the issue might lie elsewhere:

1. Meta Tags

Check if the page has a noindex meta tag.

<meta name="robots" content="noindex">  

If present, remove or modify it to:

<meta name="robots" content="index, follow">  

2. Server Configuration

Ensure your server isn’t blocking bots. Common issues include:

• IP restrictions
• Firewall rules

Contact your hosting provider to resolve these.

Best Practices for Robots.txt to Avoid Future Issues

1. Allow Important Pages
   Always allow pages like:

   Allow: /  
   

2. Block Irrelevant Pages
   Block non-SEO-critical pages like admin panels:

   Disallow: /wp-admin/  
   

3. Use Wildcards for Efficiency
   To block similar pages:

   Disallow: /private/*  
   

4. Regularly Audit Your Robots.txt File
   Periodically review your robots.txt file for outdated or unnecessary rules.

FAQs

1. Can I completely remove the robots.txt file?

Yes, but it’s not recommended. Without a robots.txt file, bots will crawl everything, including irrelevant pages.

2. How long does it take for Google to re-crawl fixed pages?

Google usually re-crawls within a few days, but you can speed it up by requesting re-indexing in Search Console.

3. Are all bots affected by robots.txt?

No. Some bots, like malicious scrapers, ignore robots.txt directives.
