A good search engine is one when users come very regularly, type their queries, get their results, and leave quickly. With user engagement metrics from web analytics, these translate to a low dwell time, often low CTR, but a very high return rate. But user engagement is not just about this. User engagement is a complex phenomenon that requires a number of approaches for its measurement: we can ask the user about their experience though questionnaires, we can observe where they look or move the mouse, and we can calculate various web analytic metrics. The aim of this talk is to discuss how current work on user engagement, not necessary specific to web search, can provide insights into putting search into more broader perspectives.
