Mobile attribution is the process of identifying which marketing channel, campaign, ad or partner drove a specific user to install your mobile app or take a desired action. It answers the fundamental question: where did this user come from?
How Mobile Attribution Works
When a user clicks on an ad, the attribution platform records a unique click fingerprint — including device information, IP address, and timestamp. When the user later installs the app and opens it for the first time, the attribution SDK matches the install to the earlier click and attributes the install to that specific ad campaign.
Attribution Methods
Deterministic Attribution
Uses exact device identifiers (IDFA on iOS, GAID on Android) to precisely match a click to an install. Highly accurate but requires user consent on iOS 14.5+ due to Apple's ATT framework.
Probabilistic Attribution
Uses statistical modeling based on device fingerprinting (IP address, user agent, screen size) when device IDs are unavailable. Less precise but works without explicit user consent.
Click-Through Attribution (CTA)
Attributes an install to the last ad the user clicked before installing. The standard attribution model used by most platforms.
View-Through Attribution (VTA)
Gives attribution credit to an ad the user saw but didn't click, typically with a shorter window (1-24 hours).
Why Mobile Attribution Matters
- Optimize ad spend — Know which campaigns drive the most valuable users and allocate budget accordingly
- Measure true ROI — Compare the cost of acquiring users from different channels against their lifetime value
- Detect fraud — Identify fake installs from bot traffic and click injection schemes
- Improve creative — Understand which ad creatives drive installs and post-install engagement
- Partner accountability — Hold marketing agencies and networks accountable for real results
Attribution Windows
| Window Type | Typical Duration | Description |
|---|---|---|
| Click-through window | 7-30 days | Time between click and install for attribution |
| View-through window | 1-24 hours | Time between ad view and install for attribution |
| Re-engagement window | 7-30 days | Time for attributing re-engagement campaigns |

Mobile Attribution vs Web Analytics
Web analytics tools like Google Analytics track website visitors using cookies. Mobile attribution uses device identifiers and probabilistic matching to track app installs across the app store ecosystem — a fundamentally different technical challenge.
