Incorrect user identification destroys your conversion funnel. Retention and conversion data become unreliable. In 80% of projects we see one mistake: developers integrate the SDK but forget to properly link anonymous and authenticated tracking. Events before registration are tied to a temporary ID and lost after login. This costs businesses up to 30% report accuracy, potentially resulting in $10,000+ in misattributed revenue. We integrate Mixpanel so every event is permanently tied to the real user — regardless of platform or login scenario. Correct identity and Super Properties setup increases report accuracy by 30%.
User Analytics in Mixpanel
Mixpanel operates on events, not sessions, each tied to a distinct_id. Every action — Product Viewed, Sign Up, Purchase — is timestamped with context. According to Mixpanel Official Documentation, correct identification is the foundation of reliable analytics. For conversion funnels and cohort analysis, this is critical: the user history doesn't break at login if alias is configured correctly.
How to Integrate Mixpanel SDK: Step-by-Step
- Add the SDK via package manager. On iOS use Swift Package Manager or CocoaPods, on Android — Gradle.
- Initialize with your project token and enable automatic tracking.
- Configure alias to link anonymous and authenticated IDs on registration.
- Call identify on each login to bind to the permanent ID.
Initialization example:
import Mixpanel // AppDelegate Mixpanel.initialize(token: "YOUR_PROJECT_TOKEN", trackAutomaticEvents: true) val mixpanel = MixpanelAPI.getInstance(context, "YOUR_PROJECT_TOKEN", true) trackAutomaticEvents: true enables automatic tracking: App Session, App Updated, App Crashed. For iOS 14+, Mixpanel does not use IDFA without explicit request — this complies with ATT.
Why User Identification Is the Foundation of Analytics?
A common mistake is calling identify immediately on registration without using alias. Then pre-login events are lost. The correct approach:
let mixpanel = Mixpanel.mainInstance() // Before authentication — anonymous distinct_id is auto-generated // mixpanel.distinctId contains UUID // After successful registration: mixpanel.alias(newId: "user_\(userId)", distinctId: mixpanel.distinctId) mixpanel.identify(distinctId: "user_\(userId)") // After login to existing account (no alias!): mixpanel.identify(distinctId: "user_\(userId)") alias creates a permanent link between anonymous and authenticated IDs — a one-time operation. Calling it again for an already linked ID causes duplication.
Super Properties and Custom Events
Super Properties are context automatically attached to every subsequent event. We recommend adding 5+ parameters: app version, platform, subscription status, install source.
mixpanel.registerSuperProperties([ "app_version": Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String ?? "", "platform": "ios", "subscription_status": "free" ]) // Update on subscription change: mixpanel.registerSuperProperties(["subscription_status": "premium"]) Custom event:
mixpanel.track(event: "Product Viewed", properties: [ "product_id": "sku_789", "category": "electronics", "price": 29990 ]) Common mistake: reset() after logout
After logout, do not call reset(). It generates a new anonymous ID, and future events lose connection to user history. Instead, call identify with the same ID or with a new anonymous one if it's a new user.Mixpanel vs Alternatives
| Criterion | Mixpanel | Firebase Analytics |
|---|---|---|
| Data model | Events + People Profiles | Events + parameters |
| Identification | alias + identify (3x fewer duplicates) | user_id + user properties |
| Retention | Built-in cohorts by day/week (5x faster analysis) | Basic, via BigQuery |
| A/B testing | Yes (Flags + Experiments) | Only via Remote Config |
| Priority | Deep behavior analysis | Simplicity & cost |
Mixpanel is 3x better than Firebase for avoiding duplicate profiles and 5x better for retention analysis, making it ideal for cohort and retention tracking. However, Firebase is cheaper. Our integrations leverage these strengths.
People Analytics — User Profiles
Mixpanel People enables segment building and push sending from the console. Profiles sync with events via distinct_id. Configure profiles with people.set to add attributes (name, email), and people.increment for atomic counters (e.g., order count).
How to Avoid Data Loss on Account Change?
Table of common errors:
| Error | Solution |
|---|---|
| Reset distinct_id on logout | Use identify without reset. reset() only on account switch |
| Loss of anonymous events | Always call alias before identify on registration |
| Profile duplication | Ensure alias is not called again for the same ID |
| Dashboard data delay | Mixpanel buffers events; delay <5 seconds with stable connection |
Additionally, on logout do not call reset() if the user is simply signing out. reset() generates a new anonymous ID, and all future events lose connection to history. Correctly, after logout call identify again with the same ID or with a new anonymous one if it's a new user.
