CPC (cost per click)
What each click through to a website, app store or landing page cost.
Also called: cost per click
Formula
CPC = cost ÷ clicks
CPC matters when a campaign is meant to send people somewhere. For influencer work it needs a way to count clicks: a tracked link, a link sticker in a story, or a unique landing page per creator.
A low CPC is only good if the clicks turn into something. A creator whose audience clicks a lot and buys nothing has a cheap CPC and an expensive CPA, so read the two together.
