Measuring what produces clients

ROAS · Return On Ad Spend

In plain terms

For each franc spent on advertising, how many francs of revenue came back.

Formula

Technical meaning

A ratio calculated by advertising platforms from the conversions they attribute to themselves. Useful for comparing campaigns, misleading for judging a whole setup: each platform counts its own conversions and ignores margin. Contrast reads it campaign by campaign and complements it with MER and cost per client.

Formula

ROAS = attributed revenue ÷ ad spend
