Cost per click (CPC)
What you pay on average for each click on your ad.
Also called CPC, cost per link click
Formula
CPC = amount spent ÷ clicks, which also equals CPM ÷ (CTR × 10)
Example
At a $15 CPM and 1 percent CTR, each click costs $1.50.
Use cost per link click rather than cost per click (all), which also counts likes and profile clicks. CPC rises when impressions get dearer or fewer people click.
