engagement-analytics-tracker

Use this skill whenever the user needs help with behavioral analytics, engagement tracking, or data collection across any digital touchpoint. Trigger for: website behavioral analytics (scroll depth, form abandonment, session tracking, GTM setup, GA4 custom events), email engagement tracking (open/click/attribution via Klaviyo, Mailchimp, or custom platforms), social media engagement monitoring (owned and competitor), mobile app analytics (Firebase, Amplitude, Mixpanel, AppsFlyer), user-level engagement scoring, cohort analysis, conversion tracking, event schema design, data layer setup, attribution modeling, or any request like "track user behavior", "set up analytics", "measure engagement", "build an event schema", "track form abandonment", "email attribution", "app retention analysis", "what events should I track?", or "how do I measure X". Always use this skill — do not guess at tracking implementations from memory; patterns and APIs change.
