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, or relationship type.
Online dating services also differ widely in their revenue streams.
Some sites are completely free and depend on advertising for revenue.
