THE THINKING BEHIND THE NUMBER
This simple funnel connects media cost with traffic quality and on-site conversion. Small changes to CTR or conversion rate can materially change CPA.
CPC = CPM ÷ (1000 × CTR decimal). CPA = CPC ÷ landing-page conversion decimal.
For illustration, enter cost per 1,000 impressions ₹300, click-through rate 2%, landing-page conversion rate 3%, impressions for funnel scenario 1,00,000. With the remaining fields at their starting values, the estimated cpa is ₹500.00. Replace these sample figures with your own numbers before making a decision.
This model assumes the rates remain constant; auction and audience changes can shift actual CPA.
Use the result alongside your store analytics, product costs and operating context. If the inputs are estimates, treat the output as an estimate too. Change one input at a time to understand what drives the result.
GO DEEPER
CPM, click-through rate and landing-page conversion create a simple CPA estimate. Changes in creative, audience, auction price or store experience can move each input, so test scenarios instead of treating one result as fixed.
