What is ROAS?

A return on ad spend.

CPA means the cost per action, and CPM is the cost per thousand impressions. ROAS means that you are taking the money spent and translating it to what was earned in return for such a marketing investment. This is important because, for many marketers, there will be no strict conversion of how much money should be put into the promotion of new or existing products and services. In fact, these days most marketing campaigns require outside assistance from various outlets like online advertising to make up ROAS issues.
