Definition
CPC is the average amount you pay for each click on your ad. For ecommerce the most useful version is cost per link click.
CPC explained
CPC combines CPM and click-through rate. A strong creative with a high CTR lowers CPC even when CPMs are high. Meta reports both cost per click (all) and cost per link click.
Formula
CPC = spend ÷ clicks
Example
With a 10 dollar CPM and a 1% link CTR, each link click costs about 1 dollar.
