Start from your target cost per lead
Work backwards: if a customer is worth a set amount and 1 in 5 leads closes, you can calculate what a lead is worth to you.
Split between testing and scaling
Keep part of your budget for testing new keywords and ads, and put the rest behind proven winners.
Review weekly
Pause low-performing keywords, add negatives and shift budget to campaigns with the best conversion rate.
