The Winning Formula
"Proof and Practicality Beats Promises"
The most effective angles focused on tangible proof points (comparisons, stats, before/after) rather than aspirational messaging. Plant protein skeptics need evidence, not inspiration.

Scarcity / Back in Stock
Winner3.9x
ROAS
Why it works
Social proof through sell-out history creates urgency. 'Sold out 3X' validates demand and triggers FOMO.
What Worked
- Comparison angles (whey vs plant, before/after)
- Social proof with real user testimonials
- Pain point messaging (bloat, digestion)
- Simple, data-driven claims
- UGC-style creative over polished studio shots
What Didn't Work
Epic/Drama storytelling
Too abstract for direct response. Users wanted facts, not feelings.
Complex ingredient breakdowns
Information overload. Lost users in the first 2 seconds.
Lifestyle-only imagery
Didn't differentiate from competitors. Needed product in frame.
Creative Learnings
- Conversion rate 3x higher on comparison creatives
- Users engage longer when given context vs brand
- Cold audiences need proof before product beauty
- Authenticity beats polish for health products
- Real faces > stock fitness models
- Testimonials with specific results outperform generic praise

Plant protein buyers are skeptical converts. They've tried products before. They want evidence they can trust—comparisons, real testimonials, and simple proof points. Lead with what makes you different, not what makes you good.
All Angles Tested
"AngleLab found angles we'd never have tested ourselves. The comparison messaging converted 3x better than our hero shots."
