VERDICT
Ship Creative B — UGC imagery + value framing outperforms lifestyle shots 2.4x with the brand's core audience.
WHO IT WORKS FOR
Price-sensitive women 25–34 with high ad cynicism. They distrust polished imagery but respond strongly to specific value claims.
WHAT TO CHANGE
Move the discount above the fold. 47% abandoned before seeing the value prop — it's the strongest asset, buried.
TARGETING REC
Run to Lookalike (Purchase, 1%) filtered to 25–34F. Exclude broad interest — this audience is too specific for it.
