Affiliate Conversion Calculator

Measure the conversion rate of affiliate traffic, which usually differs sharply from direct traffic.

About Affiliate Conversion Calculator

The affiliate conversion rate is the share of affiliate clicks that affiliate-driven conversions represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.
