Most ecom supplement launches on Meta fail because they treat creative like an afterthought. Targeting stopped being the lever years ago. Advantage+ already finds the audience for you. The only variable left in your control is the ad itself. Generic content can’t be salvaged.

None of this matters until you get your first 10 customers, even if that round loses money. Those 10 people are not a profit center. They are your research. Their exact words about what changed become the logline for your next round of creative.
