Product metrics instrument products and their features to measure [[product success]], [[product growth]], and/or [[product health]]. Types of product metrics include - [[north star metric]] - [[driver metric]] - [[secondary metrics]] - [[guardrail metrics]] - [[vanity metrics]] (to be avoided) ## product metric recipe A simple recipe for selecting a metric for a product, feature or experiment includes three ingredients: 1. What is the action you are measuring (e.g., clicks, views or posts)? 2. At what level do you want to measure the action ([[unit of analysis]] like user, session or month)? 3. How will you quantify the action (i.e., statistic like total, average or count)?
