How do you determine a user's health score?

The user's health score is a comprehensive metric that reflects the 'health' or level of engagement and satisfaction of the user with the product. To determine the health score, several key indicators are usually combined, such as:

• User activity (frequency and duration of sessions)
• Achievement of target actions (conversions, purchases, use of features)
• Retention rate
• Feedback (ratings, reviews)
• Technical indicators (e.g., errors or crashes during use)

Each of these parameters is assigned a weight depending on its importance to the business. Then, based on a formula or model (for example, a weighted sum), the final score is calculated.

An example of a simple approach:

Health Score = 0.4 * Activity + 0.3 * Goal achievement + 0.2 * Retention + 0.1 * Feedback

It is important to adapt the metric to the specifics of the product and regularly review it to ensure it reflects current user behavior and values.
