Understand CPC, CPM & CTR
CPC (Cost Per Click)
Formula: CPC = total_cost / number_of_clicks
Useful for campaigns focused on generating traffic to your product pages.
CPM (Cost Per Mille)
Formula: CPM = (total_cost / number_of_impressions) × 1000
Perfect for campaigns aimed at building brand awareness.
Note: Sponsored Display and Amazon DSP bill on vCPM (viewable CPM).
CTR (Click-Through Rate)
Formula: CTR = (number_of_clicks / number_of_impressions) × 100
A key benchmark to evaluate ad effectiveness.
Use these metrics to pick the right model. To plan how many impressions a budget buys, divide the budget by your target CPM and multiply by 1,000: $500 at a $5 CPM buys 100,000 impressions.
