The campaign produced a 6.2% save rate and a 10.4% playlist add rate, both well above the 2 to 4% independent-artist average. That engagement quality, not raw volume, is what triggered Spotify's algorithm: 23,596 song saves and 39,580 playlist adds compounding into sustained organic reach.
Each platform did what it does best. TikTok drove scale at $0.0003 per video view, Meta drove efficient streaming conversions with a best-campaign cost per result of $0.10, and Google Ads seeded YouTube discovery with 375,669 qualified views. Every paid click routed through FeatureFM to Spotify, where streams, saves, and playlist adds generated the organic algorithmic signals that keep working after the budget is spent. The team prioritized save rate over stream count throughout, because saves are the metric that predicts whether growth lasts.
In six months, Zoe Levert went from zero to 40,874 peak monthly listeners, 380,759 streams, 23,596 song saves, and 39,580 playlist adds, all built from scratch on $14,830 in total spend across three platforms. Spotify followers grew to 6,523.
The campaign's impact extended well beyond the platforms it ran on. Zoe charted on Apple Music in 56 countries, picked up 2,846 Shazams, and built a 137K-follower TikTok presence from organic spillover, none of which were advertised on directly. Combined with 23.1M video views and a save rate that signals genuine fans, the foundation is set for the algorithm to carry growth forward.
