Event Tracking
The practice of recording specific user interactions within a digital product, such as clicks, form submissions, page views, and feature usage, as structured data events that can be analyzed to understand user behavior.
Event tracking captures the granular interactions that reveal how users actually engage with your product. Each tracked event includes a name, timestamp, and associated properties that describe the context: which button was clicked, which page was viewed, which item was added to cart, and what state the user was in when the action occurred.
For growth teams, event tracking is the foundational data layer that powers all analytics, experimentation, and personalization. Without comprehensive, accurate event data, every downstream decision is built on incomplete information. AI applications from recommendation engines to churn prediction models depend entirely on the quality and completeness of event data. Growth engineers should design event tracking with a clear taxonomy that ensures consistency across platforms, includes all properties needed for downstream analysis, and distinguishes between different types of interactions. The most common failure mode is implementing tracking reactively, adding events only when someone needs data for a specific analysis. Proactive tracking design based on a structured taxonomy ensures that when questions arise, the data is already available to answer them.

Funnel Analysis
The process of tracking and measuring user progression through a defined sequence of steps toward a conversion goal, identifying where users drop off and quantifying the conversion rate between each stage.
Conversion Rate Analytics
The systematic measurement and analysis of the percentage of users who complete a desired action out of the total who had the opportunity, applied across multiple conversion points throughout the user journey.
Drop-Off Rate
The percentage of users who leave a process or sequence at a specific step without completing the next step, the inverse of step-level conversion rate, used to identify friction points in user flows.
Cohort Analysis
A technique that groups users by a shared characteristic or experience within a defined time period and tracks their behavior over subsequent periods, revealing how user behavior evolves and differs across groups.
DAU/MAU Ratio
The ratio of daily active users to monthly active users, expressing what percentage of monthly users engage on any given day. A higher ratio indicates stickier product engagement and stronger habitual usage patterns.
