Cost Per Click (CPC)

Cost Per Click (CPC), also known as Pay Per Click (PPC), is a digital advertising pricing model where advertisers pay a fee each time someone clicks on their ad. This model is commonly used in search engine advertising, social media advertising, and display advertising networks.

How CPC Works

In a CPC model:

Advertisers bid on keywords or placements
Ads appear to relevant users
Payment occurs only when someone clicks
Budget is controlled by bid amounts and daily limits

How to Calculate CPC

CPC = Total Cost of Campaign ÷ Number of Clicks

Example Calculation

If you spent $500 on a campaign and received 250 clicks:

CPC = $500 ÷ 250 = $2.00 per click

Profit Per Sale: $100 - $40 = $60
ROI: ($60 ÷ $40) × 100 = 150%
