Blocking Abusive Bots with host.htaccess

To block abusive bots effectively, you can add specific code to your host.htaccess file. This file acts as a gatekeeper for your website, controlling access for different user agents. Below is the code to block known abusive bots:

# Block known abusive bots

User-agent: *
Disallow: /

The above code uses the “User-agent” field, which corresponds to the bot’s user agent. The “Disallow: /” directive forbids all bots from accessing your website.

Blocking Specific Bots

If you want to block specific bots, you can add individual entries for each one. For example, to block the Baiduspider, Googlebot, and Bingbot, you would add the following lines:

User-agent: Baiduspider
Disallow: /

User-agent: Googlebot
Disallow: /

User-agent: Bingbot
Disallow: /

Blocking Bots from Specific Countries

In some cases, you may want to block bots coming from specific countries. You can achieve this by using regular expressions to target specific country codes. For example:

User-agent: .*crawl.*.ru
Disallow: /

User-agent: .*bot.*.cn
Disallow: /

The code above blocks bots with “badbot” in their user agent.

Allowing Specific Bots

In some cases, you may want to allow specific bots while blocking others. To do this, you can use the “Allow” directive. For example, to allow Googlebot access:

User-agent: Googlebot
Allow: /


Blocking abusive bots is an essential aspect of maintaining the security and integrity of your website. By effectively using the host.htaccess file and targeting specific user agents, you can thwart malicious bots from causing harm and ensure a better user experience for your website visitors.

Remember, it’s crucial to regularly update your host.htaccess file to keep up with emerging threats. By following the steps outlined in this article, you can take significant steps towards safeguarding your online platform.
