What is CPC?
CPC, or cost per click, is the average amount you pay each time someone clicks on one of your ads.

CPC (cost per click) is a billing model and a metric used in digital advertising. You pay only when someone clicks on your ad, not when they view it.
Platforms such as Google Ads and Meta Ads use this model. The cost per click depends on competition, the audience you choose, and the relevance of your ad.
Why does it matter?
CPC tells you how much it costs to bring a person to your site. It's useful for comparing campaigns and audiences, but it doesn't tell the whole story: a cheap click isn't worth anything if that person doesn't make a purchase.
That's why it's a good idea to look at it alongside the conversion rate, CPA (cost per acquisition), and ROAS (return on ad spend). Sometimes it's worth paying more per click if it reaches someone who's more likely to make a purchase.
How is it calculated?
Formula: CPC = Campaign Spend / Number of Clicks.
For example, if you spend $500 on an ad and it receives 1,000 clicks, your CPC is 500 / 1,000 = $0.50.
Story mode
An online sports store tests two campaigns. The first, targeting a broad audience, has a low CPC, but almost no one makes a purchase. The second, targeting people similar to its best customers, has a higher CPC but converts several times more. In the end, each sale costs less with the second campaign.
