Installs per mille (IPM) is the metric that separates profitable mobile game UA from money-burning UA. Higher IPM means more installs per impression, which means lower effective CPI, better network priority, and more efficient spend. The studios consistently hitting high IPM share one trait: they test more creative, more systematically, than everyone else.
Layer gives mobile game UA teams the creative production velocity that systematic IPM optimization demands. Generate 50–100+ creative variations per testing cycle. Run structured experiments that isolate what drives installs. Iterate on winners before they fatigue. Build a compounding creative intelligence that makes every testing cycle more efficient than the last.
IPM Is the UA Metric That Matters
IPM sits at the intersection of creative quality and campaign efficiency:
IPM = Installs / Impressions x 1000 Higher IPM means each impression is more valuable. You get more installs from the same spend.
Network Reward High-IPM Creative Meta, Google, TikTok, and ad networks algorithmically favor high-IPM creative with better placements and lower costs. It's a virtuous cycle.
IPM Is a Creative Metric Targeting and bidding are commoditized. The primary lever for improving IPM is creative — the visual and messaging that converts attention into installs.
Small IPM Gains Compound A 20% IPM improvement across your UA spend can mean millions in additional installs at the same budget. Creative testing is the highest-ROI activity in UA.
Layer gives you the creative volume to move IPM systematically.
Structured Creative Testing Framework
Random creative testing wastes budget. Layer supports systematic testing that produces actionable insights:
Variable Isolation Generate variations that change one element at a time — hook, character, background, CTA, color scheme. Get clean signals on what impacts IPM.
Theme Testing Run the same gameplay concept through multiple visual themes simultaneously. Find which aesthetic direction resonates with your target audience.
Funnel Stage Testing Test creative optimized for different funnel stages — top-of-funnel awareness, consideration-stage gameplay showcase, and bottom-of-funnel install urgency.
Audience Segment Testing Generate creative tailored to different audience segments — genre fans, competitive players, casual browsers. Test what visual approach converts each segment.
Structured testing that builds creative intelligence over time.
Creative Volume for Statistical Significance
Meaningful IPM testing requires volume — both creative variations and impression volume per variant:
50–100+ Variations Per Cycle Generate enough creative to saturate your testing capacity. More variations mean faster discovery of high-IPM creative.
Parallel Testing Across Channels Run creative tests simultaneously on Meta, Google, TikTok, and ad networks. Different channels may reward different creative approaches.
Rapid Succession Testing Complete weekly testing cycles instead of monthly. Layer's production speed lets you run 4x more tests per quarter.
Statistical Rigor With abundant creative, you can allocate sufficient impressions per variant for statistically significant results — not declare "winners" from noisy data.

Winner Iteration and Fatigue Prevention
Finding high-IPM creative is half the battle. Sustaining performance is the other half:
Winner Extension When a creative achieves high IPM, immediately generate 20+ variations exploring that theme. Extend the winner's lifecycle by introducing fresh versions before the original fatigues.
Fatigue Prediction Track creative performance curves. When IPM begins declining (typically 5–14 days), have replacement creative ready to rotate in.
Theme Evolution Evolve winning themes gradually rather than replacing them entirely. Generate variations that shift the visual while preserving the hook that drives installs.
Seasonal Winner Adaptation Adapt high-performing creative for seasonal events and game updates. Apply the winning formula to new contexts.
Sustained high IPM through continuous creative evolution.
Creative Intelligence Loop
Layer helps you build compounding knowledge about what drives IPM for your game:
Performance Tagging Tag creative by visual element — hook type, character, background, CTA style, color scheme. Map IPM data back to specific creative decisions.
Pattern Recognition After 3–5 testing cycles, clear patterns emerge: which characters drive installs, which hooks stop the scroll, which CTAs convert. Apply these patterns to future creative generation.
Creative Playbooks Build documented playbooks of winning creative approaches. New team members generate high-IPM creative from day one by following proven patterns.
Cross-Game Learning For studios with multiple titles, apply creative learnings from one game's testing to another. Accelerate the testing runway for new launches.
Every testing cycle makes the next one more efficient.
Multi-Network IPM Optimization
IPM varies significantly across ad networks. Layer supports network-specific optimization:
Meta (Facebook & Instagram) Generate creative optimized for Meta's auction dynamics. Advantage+ favors creative diversity — give it volume.
TikTok Produce native-feeling vertical creative that earns high IPM in TikTok's fast-scroll environment.
Google UAC Supply all responsive formats so Google's algorithm has maximum creative to optimize against.
Unity Ads, ironSource, AppLovin Generate end cards and interstitials optimized for in-app network IPM. Different visual approaches win on different networks.
