Post Affiliate Pro - Affiliate Program Software, Tracking, Marketing

Action Commissions feature allows you to define per action, or per "anything" commissions.

Average affiliate software has limits and you can track just sales or leads. Post Affiliate Pro allows you to track ANY action and pay Commissions Per Action (CPA) to your affiliates.

This way you can define commissions for example per user registration, per download, per visiting specific page, etc.
You can create unlimited number of per action commissions in every campaign, which gives you the ability to track virtually every visitor's move.
