Player acquisition in iGaming is expensive, so the payback on traffic is determined by what happens after the first deposit. Retention describes that behaviour, but it is not captured by a single number: operators look at a set of indicators, each of which answers its own question.
The cohort view
The basic construct is the cohort: a group of players who arrived in the same period, observed at fixed checkpoints. The share returning on day one, day seven and day thirty characterises the quality of the traffic source and of the first experience. Comparing cohorts across channels explains why buys of the same size deliver different results.
What is watched besides returns
- session frequency and the interval between sessions;
- the share of players making a second deposit and the time it takes;
- the average deposit and how it moves within the cohort;
- churn, meaning the share of players inactive for longer than an agreed period.
The contribution of bonus mechanics is assessed separately: a rise in activity during a promotion proves nothing on its own, what matters is how the cohort behaves once the promotion has ended.
The link with responsible gaming
Retention metrics overlap with the monitoring of risky behaviour: a sharp increase in session or deposit frequency is a signal not only for CRM but for the responsible gaming team. In tightly regulated jurisdictions these systems are required to be connected.
Retention reads best alongside acquisition economics: separated from the cost of the channel, it does not answer the question of payback.
