Why CPC alone is not enough
CPC tells you what each click costs, but it does not tell whether the traffic is profitable. This calculator also shows conversion rate, cost per conversion and revenue per click when those inputs are available.
Example
If a campaign spends $500 for 1,000 clicks, CPC is $0.50. If those clicks produce 50 conversions, cost per conversion is $10.
Common mistakes
Do not optimize only for cheap clicks. Compare CPC with conversion rate, lead quality, revenue per click and campaign objective.
