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.The 2016 Pew Research Center's survey reveals that the usage of online dating sites by American adults increased from 9% in 2013, to 12% in 2015.Further, during this period, the usage among 18- to 24-year-olds tripled, while that among 55- to 65-year-olds doubled.At the end of November 2004, there were 844 lifestyle and dating sites, a 38% increase since the start of the year, according to Hitwise Inc.
Some have a broad membership base of diverse users looking for many different types of relationships.
Over 50% of research participants in a 2011 study did not view online dating as a dangerous activity, whereas 43% thought that online dating involved risk.
Because online dating takes place in virtual space, it is possible for profile information to be misrepresented or falsified.
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.
That is, online dating sites use the conceptual framework of a "marketplace metaphor" to help people find potential matches, with layouts and functionalities that make it easy to quickly browse and select profiles in a manner similar to how one might browse an online store.
