What is Conversion rate?
conversion
Conversion rate is the share of people who take the next step: for example, how many leads become customers. Divide those who completed the step by those who started.
Example
Out of 50 leads, 5 become customers: lead-to-customer conversion is 5 / 50 = 10%.
Why it matters
Two campaigns with the same CPL can behave very differently: one brings buyers, the other only tire-kickers. Conversion shows the gap. You can estimate quickly with the ROAS and cost-per-lead calculator.
