NextBee Media offers a software platform for cost per action (CPA) advertising. CPA advertising allows advertisers to pay only when a visitor performs a desired action like a click, sale, or lead. The document provides an outline of tips for CPA campaign execution including setting realistic targets, controlling the campaign budget, reviewing partner site performance, and using additional features like referral widgets, contests, and reviews. Advertisers are advised to switch to CPA if other campaign types have failed or to use CPA if they have a lead-based business.
