A PPC campaign is not measured in pure clicks. It's not measured by how little you spend on a click. We can't even measure it by conversions alone.

The growth of your business all depends on this question.
How much does it cost to acquire new customers and how much is that customer worth? How much money will they typically make once they become a customer? What ROI do you need for your pay-per-click advertising campaigns? 5X, 10X, 15X?
Let's review the basics of PPC advertising and explore how to achieve high ROI.
