CPC (Cost Per Click)

CPC stands for cost per click and is the dominant pricing model for performance ads on Google Ads, Meta Ads, TikTok Ads, and most affiliate networks. Instead of paying for impressions, the advertiser pays only when a real user clicks the ad. For creators running affiliate or sponsored campaigns, CPC matters because it shows up in two places at once: as the price brands pay for traffic, and as the rate creators are paid in CPC-based affiliate programs (rare today but still common in news and finance). CPC is also the key driver of EPC (earnings per click), the metric serious affiliates use to compare programs head-to-head.

CPC matters because it is the cleanest price for intent. A click is a real action — someone interested enough to leave one page and go to another. For brands, low CPC + high conversion = scalable acquisition. For creators, understanding the CPC their content drives helps them negotiate higher flat fees from sponsors.
