Core Digital Marketing KPI Formulas
// 1. Click-Through Rate (CTR %)
CTR = (Clicks / Impressions) * 100
// 2. Conversion Rate (CR %)
Conversion Rate = (Conversions / Total Clicks or Visits) * 100
// 3. Cost Per Click (CPC)
CPC = Total Ad Spend / Total Clicks
// 4. Cost Per Mille / Thousand Impressions (CPM)
CPM = (Total Ad Spend / Total Impressions) * 1000
// 5. Cost Per Acquisition / Lead (CPA / CPL)
CPA = Total Ad Spend / Total Conversions (or Leads)
// 6. Return On Ad Spend (ROAS)
ROAS = Revenue Attributed to Ads / Total Ad Spend
// 7. Return On Investment (ROI %)
ROI % = ((Total Revenue - Total Cost) / Total Cost) * 100
🎯 Interview Q: What is the difference between ROAS and ROI?
ROAS (Return On Ad Spend): Evaluates ad campaign efficiency directly by comparing revenue from ads to ad spend (`Gross Revenue / Ad Cost`).
ROI (Return On Investment): Evaluates net business profitability by accounting for all costs including software, salaries, production, and ad spend (`(Net Profit / Total Cost) * 100`).
