A great diversity of online dating services currently exists (see Comparison of online dating services).

Some have a broad membership base of diverse users looking for many different types of relationships.

Other sites target highly specific demographics based on features like shared interests, location, religion, sexual orientation or relationship type.

Online dating services also differ widely in their revenue streams.

The 2016 Pew Research Center's survey reveals that the usage of online dating sites by American adults increased from 9% in 2013, to 12% in 2015.
