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.
Online dating services also differ widely in their revenue streams.
Some sites are completely free and depend on advertising for revenue.
Members can constrain their interactions to the online space, or they can arrange a date to meet in person.
A great diversity of online dating services currently exists.
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.

Online dating (or Internet dating) is a system that enables strangers to find and introduce themselves to new personal connections over the Internet, usually with the goal of developing personal, romantic, or sexual relationships.
Since advertising revenues are modest compared to membership fees, this model requires a large number of page views to achieve profitability.
