What is CPC?
Cost-per-click, either an amount actually paid for a click, or an amount calculated for comparison purposes.
What is a good CPC?
Whatever maximizes your profit.
You don’t not want to overpay, but it’s unlikely you will conversions solely with cheap clicks.
CPC costs vary based on…
- number of competitors
- aggressiveness of competitors
- profitability of industry
- scarcity of inventory
Ad platforms like Google will give you estimates on how much clicks cost.
For major industries, there might also be 3rd-party research on CPC trends.
