What is Attribution?

Definition, examples, and more

Definition

The process of identifying which marketing source (e.g., paid ad, referral, email) led a user to install the app or subscribe. Accurate attribution is essential for measuring ROI, optimizing campaign performance, and understanding how different channels contribute to growth.

Example

A news app tracks that 30% of its subscribers come from Apple Search Ads, 25% from TikTok campaigns, 20% from organic search, and 25% from referrals. However, when they analyze 90-day LTV by channel, referral users generate 3x more revenue — revealing that not all installs are created equal.

Why Attribution Matters

Without proper attribution, you are flying blind with your marketing budget. A photo editing app was spending $50K/month on Facebook ads thinking it was their top channel. After implementing proper attribution through an MMP, they discovered that 40% of those ‘Facebook installs’ were actually organic users who would have downloaded anyway — saving them $20K/month in wasted spend.

Frequently Asked Questions

How does Apple’s App Tracking Transparency (ATT) affect attribution?

ATT requires apps to ask permission before tracking users across other apps and websites. With only 20-35% of users opting in, deterministic attribution has become much harder. Most apps now rely on probabilistic modeling, SKAdNetwork (Apple’s privacy-preserving framework), and first-party data to fill the gaps.

What is the difference between last-touch and multi-touch attribution?

Last-touch gives 100% credit to the final interaction before install (e.g., the ad they clicked). Multi-touch distributes credit across all touchpoints in the user journey. For subscription apps, multi-touch is more accurate since users often see multiple ads before converting, but it is harder to implement.

Do I need an MMP for attribution?

If you are spending money on paid acquisition across multiple channels, yes. MMPs like AppsFlyer, Adjust, and Branch provide unified attribution across ad networks, handle deduplication, and integrate with platforms like Botsi for downstream revenue tracking. Without one, you will likely double-count installs and misallocate budget.

More terms starting with “A

A/B testing

A method of product experimentation in which users are randomly split into two or more cohorts (e.g., Group A and Group B), with each group exposed to a different variation of a feature such as copy, design, or pricing. A primary success metric is established before the test begins, and the outcome is typically measured using frequentist statistics and confidence intervals to determine if one version outperforms the other — or if results are inconclusive.

Activation

A key stage in the customer lifecycle that occurs after acquisition. Activation is defined by a user completing a high-value action for the first time — such as starting a trial, making a purchase, or engaging with a core feature. The exact definition depends on the app’s monetization model and business goals.

Active subscriber

A user who currently has an active, paid subscription. This excludes users in a grace period, trial, or lapsed state, and is typically the core population used when calculating MRR or churn rate.

App store optimization (ASO)

The process of improving an app’s visibility in app store search results and browse sections (e.g., on Apple’s App Store or Google Play). ASO involves optimizing elements like the app name, description, keywords, icon, screenshots, and video preview to drive organic installs and improve conversion rates from page views to downloads.

Apple Search Ads (ASA)

Apple’s paid user acquisition channel that displays targeted ads at the top of App Store search results. ASA allows marketers to bid on keywords, define demographic and behavioral targeting, and optimize campaigns based on user value post-install, such as subscription conversion or trial start.
