Online dating services allow users to become "members" by creating a profile and uploading personal information including (but not limited to) age, gender, sexual orientation, location, and appearance.Most services also encourage members to add photos or videos to their profile.
Other sites target highly specific demographics based on features like shared interests, location, religion, or relationship type.
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.
Opinions and usage of online dating services also differ widely.
A 2005 study of data collected by the Pew Internet & American Life Project found that individuals are more likely to use an online dating service if they use the Internet for a greater number of tasks, and less likely to use such a service if they are trusting of others.
