Online Gambling is a multibillion-dollar business, but for millions of people, it can be dangerous. The American Psychiatric Association lists gambling disorder in the category of addictive disorders, and there are concerns that people who gamble too much have increased vulnerability to other addictions, such as to alcohol or drugs.

The behavioural characteristics of online gamblers have not been studied in depth, but high impulsivity has been found to be a common feature. In some studies, this has been associated with a dysfunctional personality and with problem gambling, but in other cases the link is less clear. Other studies have found that compared to nonproblematic gamblers, online gamblers are more likely to be women and to report a lower level of sociability. In addition, the studies examining chasing losses report that this behaviour is more often observed in online than in offline gamblers.

Many of the studies are cross-sectional and do not use representative samples. In addition, the focus on risk and protective factors is limited. It would be beneficial to focus on longitudinal studies and examine the relationships between these variables.

Developing a successful online casino website requires careful planning and a solid marketing strategy. The site needs to be easy to navigate and offer a variety of games and promotions. It also needs to be secure and offer a number of payment options. Marketing strategies can include pay-per-click advertising, social media engagement, gamification, surveys, feedback, and special events to attract and retain customers.
