Mobile attribution is the backbone of performance marketing. Without accurate attribution, you're flying blind—unable to determine which campaigns drive installs, which channels deliver quality users, or where to allocate your budget. This comprehensive guide will teach you everything you need to know about mobile attribution.
What is Mobile Attribution?
Mobile attribution is the process of identifying which marketing touchpoint (ad, channel, campaign) led a user to install your app. It connects advertising spend to measurable outcomes, enabling data-driven optimization.
Why Attribution Matters
Without attribution, a $100,000 monthly ad budget is essentially gambling. With proper attribution, you know exactly which $50,000 drives 80% of your quality installs—and can cut the waste.
How Mobile Attribution Works
The attribution process involves several key steps:
- Ad Interaction: User sees or clicks on your ad
- Data Capture: Attribution provider records device identifiers, timestamps, and campaign data
- App Install: User downloads and opens your app
- Matching: SDK matches the install to the recorded ad interaction
- Attribution: Install is credited to the correct campaign/source
Attribution Models
| Model | How It Works | Best For |
|---|---|---|
| Last Click | Credits the last ad clicked before install | Direct response campaigns |
| Last Touch | Credits the last interaction (view or click) | Full-funnel measurement |
| First Click | Credits the first ad interaction | Awareness campaigns |
| Multi-Touch | Distributes credit across touchpoints | Complex user journeys |
Attribution Windows
Attribution windows define how long after an ad interaction an install can be credited:
- Click-through window: Typically 7-30 days
- View-through window: Typically 1-24 hours
- Re-engagement window: Varies by campaign goals
Setting Optimal Windows
Shorter windows reduce false attributions but may miss legitimate installs. Longer windows capture more installs but risk crediting unrelated ad exposures. Test to find your optimal balance.
Post-ATT Attribution (iOS 14.5+)
Apple's App Tracking Transparency changed everything. With limited IDFA access, attribution now relies on:
- SKAdNetwork: Apple's privacy-preserving framework
- Probabilistic matching: Statistical modeling without device IDs
- First-party data: Your own user data and analytics
- Aggregated measurement: Cohort-based insights
Choosing an MMP (Mobile Measurement Partner)
Key factors when selecting an attribution provider:
- Integration ecosystem (ad networks, analytics tools)
- Fraud detection capabilities
- SKAdNetwork support and optimization
- Data privacy compliance
- Pricing model and scale
