Funnel stage
Across 42 creatives in the cpg & household account, curiosity gap angles were the clear winner this cycle. An incomplete loop in the first 3 seconds ('The reason your last 3 didn't work isn't what you think') held attention long enough to earn the pitch. We rotated 4 hook families against BOF cart abandon and logged what actually moved CPA.
The setup
This account sits in CPG & Household. Going in, the brand was over-reliant on one fatigued angle and CPA had crept to $10 on BOF cart abandon. We structured a 3-cell test isolating the hook variable: same offer, same landing page, same audience — only the first 3 seconds changed. Budget was held flat at $127k so the read was clean.
Hook angle: Curiosity gap
An incomplete loop in the first 3 seconds ('The reason your last 3 didn't work isn't what you think') held attention long enough to earn the pitch. Pairing it with a fast cut kept thumb-stop rate high. In this cpg & household account it returned a 3.3x ROAS at a 3.03% hook CTR. This was our top performer and is now the control we test everything else against.
Hook angle: FOMO / urgency
Genuine scarcity ('Restock sold out in 9 hrs last time') drove BOF urgency. Fabricated urgency hurt trust — only deployed when the constraint was real. In this cpg & household account it returned a 3.0x ROAS at a 2.27% hook CTR. Solid mid-pack — worth keeping in rotation to fight fatigue on the winner.
Hook angle: Statistic shock
A jarring stat ('92% of these expire unused') reframed the buyer's status quo as risky. Sourcing the stat on-screen added credibility and reduced 'too good to be true' bounce. In this cpg & household account it returned a 3.0x ROAS at a 1.12% hook CTR. Solid mid-pack — worth keeping in rotation to fight fatigue on the winner.
Hook angle: Bold claim
A specific, almost-uncomfortable promise out-converted vague benefit language. Specificity ('replaces 4 products') read as confidence, not hype — when we could back it up. In this cpg & household account it returned a 5.1x ROAS at a 1.32% hook CTR. Solid mid-pack — worth keeping in rotation to fight fatigue on the winner.
What actually moved the needle
The winning curiosity gap concept cut CPA to $10 and pushed blended ROAS to 3.2x. The biggest lever was the first frame: curiosity gap openers earned a 26% 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 cpg & household, lead with curiosity gap — 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 14 days before fatigue spikes CPA. 4) Keep fomo / urgency, statistic shock, bold claim in rotation as fatigue insurance. 5) Raw, captioned, mobile-first creative beats studio polish on cold BOF cart abandon.
