Start with customer value
Work out what a typical customer is worth over time, not just their first purchase. That sets how much you can afford to acquire one.
Separate management from media
Management fees pay for the people running the system; ad spend goes to Google or Meta. Budget for both.
Give it long enough
Campaigns need time to learn and follow-up needs time to convert. Judge results over months, not days.
Measure the right thing
Track cost per enquiry and cost per customer. If you cannot see those, fix tracking before increasing spend.
