3 Ways To Calculate PPC ROI. Calculating ROI is one of the basic tenets of PPC, and yet many advertisers don’t consider it or even understand it.

A lot of advertisers perform campaign optimizations based solely on conversion rate or cost per conversion, choosing the ads and keywords with the best metric and calling it a day. This might be sufficient if you’re collecting leads and not selling goods. You’ll probably end up with more leads in the end.
