FAQ

Common questions

What is CTR?

Click-through rate is clicks divided by impressions, shown as a percentage. It tells you how compelling an ad is to the people who saw it, but it does not tell you anything about conversion or revenue on its own.

What is CPC?

Cost per click is total cost divided by clicks. It is the average price you paid to bring someone to your site or landing page.

What is CPM?

Cost per mille is cost divided by impressions, multiplied by 1000. It is the price to serve your ad 1000 times, and it is the standard unit for comparing awareness placements.

What is CPA?

Cost per acquisition is cost divided by conversions. It tells you how much you paid to get one conversion, which is usually a purchase, a signup or a qualified lead.
