The most frequently asked question, and the honest answer is dull: the spread is so wide that an average describes nobody.
Why there is no average
The same sample contains someone who lost money over a month of tests and a team with tuned setups and dozens of accounts. The average between them is a number nobody has.
What income is made of
Income = volume × conversion × payout − costs. Four multipliers that grow differently.
- Volume is capped by fleet and limits. Grows linearly and slowly.
- Conversion is audience and approach quality. Grows in jumps when a working setup is found.
- Payout is set by the offer and barely in your control.
- Costs grow with volume but slower — which is what makes scale profitable.
Reading case studies
Look not at the total but at three things: over what period, on what investment, and what is missing from the costs. Usually missing: accounts, time, and the failed tests before this one.
A realistic first quarter
Month one negative. Month two around break-even. Month three the first profit, if a setup was found. That curve means you are doing it right. How to count your own numbers is in unit economics.
