Difference between CPM, CPC, and CPA in PPC Advertising

CPM (Cost Per Mille), CPC (Cost Per Click), and CPA (Cost Per Acquisition) are common pricing models used in PPC (Pay-Per-Click) advertising.

• CPM: CPM stands for Cost Per Mille, where Mille refers to a thousand impressions. In the CPM model, advertisers pay for every 1,000 impressions their ad receives, regardless of whether users interact with the ad or not.
• CPC: CPC stands for Cost Per Click. In the CPC model, advertisers pay each time a user clicks on their ad. It is a performance-based pricing model where advertisers only pay when users engage with the ad by clicking on it.
• CPA: CPA stands for Cost Per Acquisition. In the CPA model, advertisers pay only when a specific action, such as a purchase or sign-up, is completed as a result of the ad. Advertisers are charged based on the successful acquisition of customers or leads.

In summary, CPM focuses on impressions, CPC focuses on clicks, and CPA focuses on actions or acquisitions. Each pricing model has its own advantages and is used based on the campaign objectives and goals.
