Conversion Rate

The percentage of users who complete a desired action after seeing or clicking an ad.

Definition

Conversion rate measures the percentage of visitors who complete a desired action.

Formula

Conversion Rate = (Conversions ÷ Clicks) × 100

Benchmarks by Industry

  • E-commerce: 2-3%
  • SaaS: 3-5%
  • Lead Gen: 10-15%

Why It Matters

Conversion rate measures the percentage of visitors who take a desired action. Even small improvements in conversion rate compound into significant revenue gains — doubling your conversion rate from 2% to 4% effectively doubles your revenue from the same traffic and ad spend. It's one of the highest-leverage metrics to optimize.

Examples

  • A landing page converting 3% of visitors into email subscribers
  • An e-commerce store with a 2.5% purchase conversion rate from all traffic sources
  • A lead form ad with a 15% form completion rate from clicks

Common Mistakes

  • Focusing on driving more traffic instead of converting existing traffic better
  • Comparing conversion rates across different traffic sources without accounting for intent differences
  • Making multiple page changes at once and not knowing which change improved the rate
