there was a wordpress plugin especially for CPA marketers . which did the following . I forgot its name and can't find it anymore. maybe you can help . Code: http://example.com/review?parameter=magicid Now this plugin will straight away redirect http://example.com/review to the affiliate offer ONLY if the parameter matches the magic id , otherwise a simple wordpress post is shown. long story short it masks the traffic source . Can anyone point to this particular plugin ? Or any other good option?
