MOF retargeting
Funnel stage
Across 53 creatives in the fitness & supplements account, before & after angles were the clear winner this cycle. Visual transformation in the first frame did the heavy lifting. We rotated 2 hook families against MOF retargeting and logged what actually moved CPA.
The setup
This account sits in Fitness & Supplements. Going in, the brand was over-reliant on one fatigued angle and CPA had crept to $36 on MOF retargeting. We structured a 8-cell test isolating the hook variable: same offer, same landing page, same audience — only the first 3 seconds changed. Budget was held flat at $28k so the read was clean.
Hook angle: Before & after
Visual transformation in the first frame did the heavy lifting. Real, slightly-imperfect afters out-pulled glossy ones — believability beat aspiration. In this fitness & supplements account it returned a 2.9x ROAS at a 1.31% hook CTR. This was our top performer and is now the control we test everything else against.
Hook angle: Negative angle
Leading with what NOT to do ('Stop buying collagen until you read this') interrupted the scroll. Negative framing earned the click; the body had to pivot fast to the positive. In this fitness & supplements account it returned a 4.1x ROAS at a 3.51% hook CTR. Solid mid-pack — worth keeping in rotation to fight fatigue on the winner.
What actually moved the needle
The winning before & after concept cut CPA to $36 and pushed blended ROAS to 3.7x. The biggest lever was the first frame: before & after openers earned a 23% 3-second view rate vs. the account average. Creative format mattered too — raw UGC out-pulled produced spots, and on-screen captions lifted hold rate by double digits.
What flopped
Generic benefit-led and over-produced brand spots underperformed on cold traffic — high impressions, weak CTR, expensive clicks. Anything that buried the hook past 5 seconds never recovered. Discounts-first messaging trained the audience to wait for sales and dented LTV.
Orange Line takeaways
1) For fitness & supplements, lead with before & after — it qualifies the buyer in the first frame. 2) Hold the offer and page constant when testing hooks so the read stays clean. 3) Refresh the winner every 10 days before fatigue spikes CPA. 4) Keep negative angle in rotation as fatigue insurance. 5) Raw, captioned, mobile-first creative beats studio polish on cold MOF retargeting.
