📊 PPC Metrics
What is PPC (Pay-Per-Click)?
PPC (Pay-Per-Click) is an advertising model where advertisers pay a fee each time their ad is clicked. Major PPC platforms include Google Ads, Facebook Ads, and Amazon Sponsored Products. PPC is one of the most effective ways to drive targeted traffic to your website or landing page. Understanding PPC metrics like CPA, CTR, and ROAS is essential for optimizing campaign profitability.
How to Calculate PPC Metrics
Follow these steps to calculate your PPC campaign metrics accurately:
- Enter your Ad Spend ($) - total amount spent on advertising
- Enter your Impressions - number of times your ad was shown
- Enter your Clicks - number of times your ad was clicked
- Enter your Conversions - number of desired actions completed
- Enter your Revenue ($) - total revenue from conversions
- Results show CPC, CPA, CTR, conversion rate, ROAS, and ROI
PPC Formulas
CPC (Cost Per Click) = Ad Spend ÷ Clicks
CPA (Cost Per Acquisition) = Ad Spend ÷ Conversions
CTR (Click-Through Rate) = (Clicks ÷ Impressions) × 100%
Conversion Rate = (Conversions ÷ Clicks) × 100%
ROAS (Return on Ad Spend) = Revenue ÷ Ad Spend
ROI = ((Revenue - Ad Spend) ÷ Ad Spend) × 100%
Real-World Example
Example: You spend $1,000 on Google Ads, get 50,000 impressions, 1,000 clicks, 50 conversions, and $5,000 revenue:
CPC: $1,000 ÷ 1,000 = $1.00
CPA: $1,000 ÷ 50 = $20.00
CTR: (1,000 ÷ 50,000) × 100% = 2.00%
ROAS: $5,000 ÷ $1,000 = 5.0x
Profit: $5,000 - $1,000 = $4,000
