How to Block Search Bots from Accessing Your Site Print

  • 1

While search bots from major search engines like Google or Bing are crucial for indexing your site for search results, there may be instances where you need to block these bots from accessing certain parts of your site or the entire site. This could be due to various reasons such as privacy concerns, content in development, or to prevent bandwidth issues caused by crawler bots. 

Using robots.txt to Control Bot Access

The primary method for controlling search bot access is through a robots.txt file. This file, placed in the root directory of your website, tells search bots which pages they should and should not index.

Creating a robots.txt File

1. Create a New Text File:
Start by creating a new text document on your computer.

2. Add Rules:
Specify which bots to block and which directories to restrict. For example:

User-agent: *
Disallow: /

This code blocks all bots from accessing the entire site. To block specific bots, replace * with the bot's name, like Googlebot.

To block all bots from accessing a specific folder, you should create a robots.txt file with the following content:

User-agent: *
Disallow: /folder/

3. Upload the File:
Upload this file to the root directory of your website, typically located at http://www.yoursite.com/robots.txt.

Using .htaccess to Block Bots

Another method, particularly for Apache servers, is using the .htaccess file. This method allows you to block bots based on their user-agent string.

Editing the .htaccess File
  • Locate or Create Your .htaccess File
    This file should be in the root directory of your site. If it’s not there, you can create a new text file named .htaccess.
  • Add Your Rules
    You can block specific bots by adding the following lines
    Replace BotName with the name of the bot you want to block.

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} BotName [NC]
RewriteRule .* - [F,L]

Considerations Before Blocking Bots

  • Blocking bots can affect your site's SEO. If search engines can't index your site, it won't appear in search results.
  • Ensure that the robots.txt and .htaccess files are configured correctly to prevent unintended blocking.
  • Bots often update their user-agent strings, so you might need to update your blocking rules regularly.

Blocking search bots can be useful for various reasons, but it's essential to understand the implications fully. By using the robots.txt file or the .htaccess file, you can control which parts of your site bots can access. Remember to use these methods responsibly to avoid adversely affecting your site's visibility and performance.
