A magnesium-based sleep supplement with loyal repeat buyers, but Meta stuck at 1.1× because the same two ads had run untouched for months.

First results in weeks

Great product, tired creative.

The formula converted and subscription retention was strong, but the account leaned on two founder-talking-head videos that had been live since launch. CPMs climbed as fatigue set in and new-customer cost crept past payback.

Two ads carrying 90% of spend, both 4+ months old
CPMs up 40% as creative fatigue compounded
No sleep-specific hooks — generic 'feel better' messaging
Zero UGC despite hundreds of five-star reviews

People who tried it stayed for months. The problem was never the product — it was that our ads had gone stale and I didn't have a system to feed new ones.

7-angle sleep hook framework
Fatigue-based rotation calendar
Review mining for real language
02
UGC & creator pipeline
Briefed 9 creators around real bedtime routines and testimonials, replacing studio talking heads with authentic footage.
9 creators briefed in month one
Bedtime-routine UGC format
Hook-first 3-second edits
03

Statics + UGC + sleep-score proof
Defined kill/scale rules

Scale & reporting
Fed winners into a lean CBO and reviewed sleep-metric-to-CAC every Monday and Wednesday.
Winner consolidation in CBO
Mon/Wed CAC check-ins
Weekly budget reallocation

From 1.1× to 3.6× in 12 weeks.

First fresh UGC angle beat the old control in week 2. By week 12 a rotating library of winners kept CAC low as budget scaled.

"We went from two burnt-out ads to a system that always has the next winner queued. CAC dropped and sleep-score testimonials now sell the product for us."
