A great diversity of online dating services currently exists.
Some have a broad membership base of diverse users looking for many different types of relationships.
Online dating (or Internet dating) is a system that enables people to find and introduce themselves to new personal connections over the Internet, usually with the goal of developing personal, romantic, or sexual relationships.
An online dating service is a company that provides specific mechanisms (generally websites or applications) for online dating through the use of Internet-connected personal computers or mobile devices.
However, Sam Yagan describes dating sites as ideal advertising platforms because of the wealth of demographic data made available by users.
Since advertising revenues are modest compared to membership fees, this model requires a large number of page views to achieve profitability.
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.
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.
