When launching ad campaign on digital platforms, take note that the pricing model you select can impact your ROI. Two of the most used and debated models are CPM vs CPA; both offer benefits unique to each model and best serve different marketing objectives. Knowing these models assists advertisers with making informed decisions relative to their strategic goal and budget at hand.
What is CPM?
CPM (Cost Per Mille) refers to a pricing model where advertisers pay for every set of one thousand impressions their ad receives. It is most commonly utilized when a brand aims to create an impression and improve its visibility within a certain target segment. Businesses that seek to increase brand visibility and reach a large audience tend to prefer CPM.

What is CPA?
CPA (Cost Per Action) is a model that charges advertisers only after a certain action has taken place. These actions include purchases made or sign ups done by the user. This approach is best suited for campaigns focused on making conversions and generating clear – cut results due to its performance based nature.
