Full-funnel ABO
Funnel stage
Across 122 creatives in the dental & orthodontics account, authority-led angles were the clear winner this cycle. Expert framing ('Dermatologists won't tell you this') borrowed credibility. We rotated 4 hook families against Full-funnel ABO and logged what actually moved CPA.
The setup
This account sits in Dental & Orthodontics. Going in, the brand was over-reliant on one fatigued angle and CPA had crept to $22 on Full-funnel ABO. 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 $59k 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 dental & orthodontics account it returned a 5.0x ROAS at a 3.18% hook CTR. This was our top performer and is now the control we test everything else against.
Hook angle: Founder story
First-person origin ('I built this after my own diagnosis') humanised the brand and lifted MOF retargeting CTR. Worked best as raw selfie-style video, not scripted. In this dental & orthodontics account it returned a 4.0x ROAS at a 1.93% hook CTR. Solid mid-pack — worth keeping in rotation to fight fatigue on the winner.
Hook angle: Myth-busting
Dismantling a category belief ('More steps ≠ better skin') positioned us as the smarter choice. Worked as carousel and long-form video for educated buyers. In this dental & orthodontics account it returned a 3.8x ROAS at a 2.52% hook CTR. Solid mid-pack — worth keeping in rotation to fight fatigue on the winner.
Hook angle: Problem-led
Opening on the visceral pain point ('Still scrubbing burnt pans by hand?') consistently beat feature-first openers. The problem statement did the qualifying for us — only the right buyer self-identified. In this dental & orthodontics account it returned a 4.9x ROAS at a 1.20% 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 $22 and pushed blended ROAS to 3.3x. The biggest lever was the first frame: authority-led openers earned a 44% 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 dental & orthodontics, 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 19 days before fatigue spikes CPA. 4) Keep founder story, myth-busting, problem-led in rotation as fatigue insurance. 5) Raw, captioned, mobile-first creative beats studio polish on cold Full-funnel ABO.
