To calculate CTC Revenue for a CPA display campaign, you take the amount of click-through-conversions (CTC) for a specific time period and you multiply it by the advertiser CPA (amount advertise agreed to pay for each acquisition you drive) for that same time period.
EXAMPLE: Steve is running a CPA display campaign for McDonald’s where the goal or KPI is to drive coupon downloads. McDonald’s is paying Steve, $1.50 for every coupon download the campaign drives. Yesterday, Steve’s CPA display campaign drove 1,489 coupon downloads, of which 984 were click-though-conversions. The CTC Revenue for McDonald’s for Yesterday is $1,476 ($1.50 x 984).
