Online dating services also differ widely in their revenue streams.Some sites are completely free and depend on advertising for revenue.In 2008, a variation of the online dating model emerged in the form of introduction sites, where members have to search and contact other members, who introduce them to other members whom they deem compatible.Introduction sites differ from the traditional online dating model, and attracted a large number of users and significant investor interest.Since advertising revenues are modest compared to membership fees, this model requires a large number of page views to achieve profitability.
Most services offer digital messaging, while others provide additional services such as webcasts, online chat, telephone chat (VOIP), and message boards.
This model also allows users to switch between free and paying status at will, with sites accepting a variety of online currencies and payment options.
Most free dating websites depend on advertising revenue, using tools such as Google Ad Sense and affiliate marketing.
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.
Such companies offer a wide variety of unmoderated matchmaking services, most of which are profile-based.
Members can constrain their interactions to the online space, or they can arrange a date to meet in person.
