Audit and diagnosis
We put the first $500 into testing broad hypotheses to confirm the baseline: CAC came out at $9 — expensive, but it gave us a solid data pool for the next rounds.
CAC Cut 3× — $9 → $3 in a VPN Project
Strategy
We built a focused action plan around the core solution: drop broad targeting and move to a 1 campaign = 1 channel/bot structure, so every source gets its own UTM link and a separately calculated CAC.
Implementation
The team completed the main work: launched across four audience segments — competitor VPN bots, niche VPN channels, news channels, and IT/Tech channels — running 507 campaigns with 13 creatives in one language over two weeks.
Testing and optimization
We ran a tight optimization loop on subscription data sent every 1–2 days, matched against UTM: campaigns above $4 CAC paused, campaigns under $3 given more budget, and top sources whitelisted and duplicated into fresh campaigns.
Scaling the result
After the loop stabilized performance, we scaled the winning sources and delivered the final outcome on $3k spend: 1,019 paying users and CAC down from $9 to $3.
