How should I read these numbers?

Every figure here is from one client account in one market over the stated window. They are records of what happened, not a forecast of what will happen for you. Spend levels, competition, pricing and the quality of the offer all move these numbers, and two practices in the same city can see very different results from identical work.

What does transfer is the method: measure before changing anything, run one variable at a time, and tie every channel back to revenue in GA4 or the CRM rather than to clicks. That is the part worth copying.

When this kind of work is the wrong call

You have no way to track what a customer is worth. Without that, none of these numbers can be reproduced or even judged.

You need results inside 30 days. Paid media can move that fast, organic search and app store work cannot.

Nobody on your side can ship changes to the site, the app listing or the follow-up. The system needs a hand on the other end.
