How to pay click commissions only for unique clicks

Post Affiliate Pro tracks all clicks on affiliate links and banners. That means if you have "per click" commission defined in your campaign it will be generated for both unique and repeated clicks by default.

Since Post Affiliate Pro version we have added option to generate click commission for unique clicks only. It's located directly in click commission settings of your campaign.

If you are using older version of Post Affiliate Pro software there is a workaround to achieve basically the same functionality. You will have to set up a fraud protection against repeating clicks in your Merchant panel->Configuration->Fraud Protection->Clicks tab, just like in the image below.
