01
Turn an order target into a CPA
Target CPA equals the available ad budget divided by the required number of orders. The result describes the average acquisition cost needed to meet both inputs.
Site conversion rate then translates that CPA into a target CPC and required click volume. This exposes when the traffic assumptions do not match recent delivery.
02
Compare the target with recent account ranges
A mathematically valid target can still be unrealistic. Compare it with recent CPA, CPC, conversion rate, audience size and the volume delivered at similar budgets.
Use a range when conversion rate or order value varies materially by device, market, offer or customer type.
FAQ
Common questions
How do I calculate target CPA?
Divide the ad budget by the number of conversions required from that budget. Then compare the result with the maximum CPA allowed by your margin.
Why does conversion rate affect target CPC?
A higher share of clicks converting into orders lets each click cost more while preserving the same CPA.
