How to measure user engagement?

User engagement is a measure of the audience's involvement with a product or service. It can be measured in various ways depending on the goals, but commonly used metrics include:

• Time spent by the user in the app or on the website.
• Number of sessions over a specific period.
• Interaction frequency (clicks, likes, comments, purchases).
• Retention rate — how many users return.

To evaluate engagement, average values of these metrics are often calculated per user or user segment. For example, average session time or average number of actions per day.

It is important to choose metrics that are relevant to the specific product and its goals.
