ClickZ / Dapper CPA Calculator Live!
Together with our friends at ClickZ, we developed this easy peasy CPA Calculator to determine how much an ‘action’ costs you as a marketer. We’ve been long pushing our agenda that marketers should pay for direct response advertising on a performance basis, and here’s a tool to help you keep your vendors honest 
It’s a pretty simple calculator that takes the CPM or CPC you’re paying and divides it by the performance (% of Clicks and % of Conversions among those clicks). This obviously leaves out the multitude of conversions that you’ll undoubtedly see as a result of post-impression conversions (user saw ad, didn’t click, but converted anyway), but for the sake of comparing campaigns across networks, media, and methods, this CPA measure is a good place to start.
We’ll follow up in the future with some more tools (perhaps one that reflects post-impression as well…). Let us know what you think!
Your blog is so informative … ..I just bookmarked you….keep up the good work!!!!
