Others utilize the freemium revenue model, offering free registration and use, with optional, paid, premium services.Still others rely solely on paid membership subscriptions.
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.
It is possible that the mode of online dating resonates with some participants' conceptual orientation towards the process of finding a romantic partner.
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.
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.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.Further, during this period, the usage among 18- to 24-year-olds tripled, while that among 55- to 65-year-olds doubled.Niche sites cater to people with special interests, such as sports fans, racing and automotive fans, medical or other professionals, people with political or religious preferences (e.g., Hindu, Jewish, Christian, Muslim, etc.), people with medical conditions (e.g., HIV , obese), or those living in rural farm communities.Since advertising revenues are modest compared to membership fees, this model requires a large number of page views to achieve profitability.
