Measuring Marketing ROI

Marketing ROI quantifies the return generated by your marketing spend. A positive ROI means your campaign generated more revenue than it cost. Common benchmarks vary by channel: email marketing typically yields 3600-4200% ROI, while PPC campaigns average 200%.

Key Metrics

  • CPL (Cost per Lead) — How much each lead costs to acquire
  • CPA (Cost per Acquisition) — How much each paying customer costs
  • Conversion Rate — Percentage of leads that become customers
  • ROAS — Revenue divided by ad spend (different from ROI)
