Chapter 01
Three coordinated fixes
What we did
- 1
Excluded all app inventory from the campaign
Biggest impact came from a single decision. App inventory inflated volume but conversion signals were noisy. Learning skewed toward low-quality actions. Once apps were removed, conversion quality snapped back immediately.
- 2
Built a conversion-focused video system
Not just "more creatives." A conversion-led structure: strong high-impact hook in the opening seconds, clear product framing early, multiple video variations from the same core script. Goal wasn't views. It was qualified action.
- 3
Layered a purchaser-based first-party audience
Built a lookalike audience from all past purchasers. Layered it into the campaign as a signal input. Anchored YouTube's learning to real buyers and accelerated post-change stabilisation.
