it is a price that you pay for each time you click on marketing campaigns.
Also called pay-per-click (PPC), cost per click (CPC) is a technique that websites use to charge based on the number of times a user clicks on an advertisement. The alternative is the cost per thousand (CPM), which is the number of opinions, or viewers, in thousands, regardless of whether every viewer clicks on the advertisement or not. Your price per click is dependent on several factors, including your maximum bid, your Quality Score, as well as the ad rank of other advertisers bidding for the same keyword.
Your CPC is an essential metric since these clicks, and costs, add up quickly. If your CPC is too high, you won’t have the ability to attain a return on your advertising investment (ROI).
