Questions from the bench
- What is a good ROAS?
- What counts as a good ROAS depends on your margin. The guide covers break-even ROAS by margin, typical ROAS by channel, and how to set a target ROAS that leaves profit.
- How do you calculate EPC?
- EPC equals commissions divided by clicks. The guide explains how to calculate earnings per click, EPC per 100 clicks, what a good EPC is, and how to use EPC to choose affiliate offers.
- What is the LTV to CAC ratio?
- The LTV:CAC ratio compares customer lifetime value to acquisition cost, with 3:1 being the common target. The guide explains how to calculate both sides correctly and how to improve the ratio.
- How long should you run an A/B test?
- A/B tests should run at least one to two weeks based on sample size by conversion rate and expected lift. The guide covers common mistakes that create false winners.
