Funnel stage
Across 102 creatives in the fitness & supplements account, authority-led angles were the clear winner this cycle. Expert framing ('Dermatologists won't tell you this') borrowed credibility. 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 $15 on MOF retargeting. We structured a 6-cell test isolating the hook variable: same offer, same landing page, same audience — only the first 3 seconds changed. Budget was held flat at $139k so the read was clean.
Hook angle: Authority-led
Expert framing ('Dermatologists won't tell you this') borrowed credibility. Pairing with a real credentialed face kept it from feeling like a gimmick. In this fitness & supplements account it returned a 4.5x ROAS at a 2.34% hook CTR. This was our top performer and is now the control we test everything else against.
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 3.3x ROAS at a 1.36% hook CTR. Solid mid-pack — worth keeping in rotation to fight fatigue on the winner.
What actually moved the needle
The winning authority-led concept cut CPA to $15 and pushed blended ROAS to 5.0x. The biggest lever was the first frame: authority-led openers earned a 42% 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 authority-led — 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 8 days before fatigue spikes CPA. 4) Keep before & after in rotation as fatigue insurance. 5) Raw, captioned, mobile-first creative beats studio polish on cold MOF retargeting.
