01 — The Challenge
Comfy needed to scale app installs profitably while improving the quality of acquired users — early campaigns were driving volume but low retention and in-app purchase rates.
02 — Strategy
Shifted optimization from install volume to value-based bidding tied to in-app purchase events.
Built platform-specific creative — short-form TikTok for awareness, Meta Advantage+ App campaigns for conversion.
Implemented event-level tracking via the Conversions API to feed cleaner signal to the algorithms.
03 — Execution
Migrated campaigns to value-based optimization once enough purchase events were flowing through CAPI.
Ran always-on TikTok awareness campaigns feeding a Meta retargeting pool for app re-engagement.
Used Google App campaigns for Performance Max-driven installs across Search, YouTube and Discover.
05 — Lessons & Future Scaling
Optimizing toward purchase value instead of raw installs transformed acquisition quality — fewer, better users outperformed cheap volume.
