Most accounts need 2–4 weeks of testing before the data is reliable enough to optimize. From there, most clients see meaningful movement within the first 30 days.

That's usually where I start. I audit your pixel, GA4, and conversion tracking before touching ad spend, since bad data leads to bad decisions no matter how good the creative is.

I test multiple creative and audience angles from day one, so underperformers get cut early and budget shifts toward what's actually converting instead of riding out a guess.

That is decided before our contract begins where we deice the terms & conditions.
