Google UAC / App Campaigns

Dominates Android UA. How UAC works, signals, campaigns, creative, bidding, measurement.

Why UAC matters

Google App campaigns (formerly UAC) is the dominant Android user-acquisition channel. Machine-learned campaign type spans Search, Play Store, YouTube, Display, Discover. Most Android apps' primary acquisition source.

How UAC works

• You provide creative assets (text, image, video, HTML5).
• Google's algorithm assembles ads dynamically.
• Algorithm decides placement across surfaces.
• Optimizes against your goal (installs or in-app actions).
• Very algorithm-driven; less granular control than other channels.

Signals UAC uses

• Google's vast user-behavior data.
• Search query intent.
• YouTube viewing history.
• App category interests.
• Demographic and location.
• Past app install patterns.
• Conversion event signals from your app.

Campaign types

• App Install: Optimize for installs.
• App Engagement: Re-engage existing users.
• App Pre-registration: Pre-launch audience building.
• Ad surfaces include Search, Play Store, YouTube, Display, Discover, Gmail.

Creative requirements

• Multiple text headlines and descriptions.
• Multiple images per aspect ratio.
• Multiple video lengths.
• HTML5 ads (optional but valuable).
• App store assets used automatically.
• Volume matters; the algorithm tests combinations.

Bidding

• Target CPI: Cost per install target.
• Target CPA: Cost per in-app action.
• Target ROAS: Return on ad spend.
• Smart Bidding requires conversion data volume.
• tROAS most powerful but data-intensive.

Measurement

• Native attribution within Google's ecosystem.
• SDK integration for in-app events.
• MMP integration for cross-channel attribution.
• Firebase integration for analytics.
• Conversion uploads for offline events.

Advanced playbook

• Creative volume strategy: 5+ headlines, 5+ images per aspect ratio, multiple videos.
• HTML5 ads for interactive engagement.
• Separate campaigns by goal (install vs engagement).
• Audience segmentation where supported.
• tROAS bidding with proper conversion value mapping.
• Firebase integration for richer events.
• App store asset optimization.
• Creative refresh cadence.
• Negative location targeting where applicable.
• Cross-campaign budget orchestration.

Common mistakes

• Insufficient creative volume; algorithm starved.
• HTML5 ads not used.
• Single campaign for install + engagement.
• tROAS without sufficient conversion data.
• Conversion value mapping incomplete.
• MMP not integrated.
• Creative refresh absent; fatigue.
• App store assets neglected.
• Cross-channel attribution misunderstood.
• Manual interference during learning.

Operating checklist

• Creative volume targets met
• HTML5 ads where supported
• Separate install / engagement campaigns
• tROAS or Target CPA bidding
• Conversion value mapping
• Firebase / MMP integrated
• Creative refresh quarterly
• App store assets current
• Cross-channel attribution understood
• Patient during learning periods
