Promoting DuckDuckGo

August 22nd, 2011 No comments

DuckDuckGo is a beautiful, fast and secure search engine, which actually cares about the users privacy and does not track you.
As too few people yet know about that amazing search engine I thought about a way how to promote it.
Here’s my solution for sysadmins and webmasters:

Include the following rewrite rule into your .htaccess on the Apache Server.

RewriteEngine On
RewriteBase /

SetEnvIf Referer "google.([_a-zA-Z-]+/)" promote_duck
SetEnvIf Referer "yahoo.com" promote_duck
SetEnvIf Referer "baidu.com" promote_duck
SetEnvIf Referer "bing.com" promote_duck

Order Allow,Deny
Allow from all
Deny from env=promote_duck
ErrorDocument 403 http://duckduckgo.com/?q=$1&kz=-1

This will cause that every referrer request by Google, Yahoo, Baidu and Bing will be redirected to DuckDuckGo, showing the according search results.

P.S. Here’s the forum discussion regarding this issue.
