CPC (Cost per Click)
CPC is the average amount paid for each click on an online ad.
CPC shows what traffic costs. It depends on competition for your audience or keywords, and on how relevant and engaging your ads are.
CPC only matters in relation to conversion rate and order value, which together decide whether clicks turn into profit.
Formula
CPC = Ad cost ÷ Clicks
Example
A campaign spends 840 for 1,200 clicks, so CPC is 0.70.
