Profiles created by real humans also have the potential to be problematic.For example, online dating sites may expose more female members in particular to stalking, fraud, and sexual violence by online predators.
Members can constrain their interactions to the online space, or they can arrange a date to meet in person.
Most free dating websites depend on advertising revenue, using tools such as Google Ad Sense and affiliate marketing.
Since advertising revenues are modest compared to membership fees, this model requires a large number of page views to achieve profitability.
Other sites target highly specific demographics based on features like shared interests, location, religion, or relationship type.
Online dating services also differ widely in their revenue streams.
