Questions, answered
How do I calculate my Google Ads budget?
Divide your target conversions by your conversion rate to get clicks, then multiply by your average CPC. 50 conversions at 4% CVR and a $1.80 CPC needs 1,250 clicks, about $2,250 a month.
What is the maximum CPC I should bid?
Max CPC = value per conversion × profit margin × conversion rate. Above that, each click costs more than it can earn back.
What target ROAS should I set?
Your minimum ROAS is 1 ÷ profit margin. With a 35% margin that is about 2.86x, or a 286% tROAS setting. Set targets above that to stay profitable.
How do I know if an A/B test result is real?
Use a significance test. The A/B calculator runs a two-proportion z-test. At 95% confidence or more, the difference is unlikely to be random.
