Mobile Install Volume Breakdown — How a Q1 Case Cut Blended CPI 16% on a 90x Organic-vs-Paid CPM Gap

A mobile game we ran in Q1 cut blended CPI by 16% — without touching their Meta budget. Effective Meta CPM in their geos: $73. Effective CPM on the organic layer we built: $0.83. Same impressions, same Tier-1 users, 90x cost gap.

Q1 produced: 23M organic views, +21% installs vs prior quarter, blended CPI $3.40 → $2.83. The Meta auction kept charging $73. The TikTok and Reels feed didn't.

This breakdown unpacks what the organic layer produces in installs for mobile studios — by vertical and by quarter.

Inside:

• Install volume by quarter from a 30-50 account organic network
• View → install conversion rates across puzzle, midcore, hypercasual, productivity
• Week-by-week install ramp across the first 90 days — when first installs hit, when volume compounds, when steady state starts
• How install volume scales across 12 months at flat content spend

Anchored on Q1 Tier-1 case ($73 vs $0.83 CPM gap, +41% installs at unchanged paid budget) + Block Blast 12-month puzzle case (180K → 342K installs/month, $2.33 → $0.08 CPI). Vertical-by-vertical conversion estimates, ramp curve, Year 1 cumulative math.
