A great diversity of online dating services currently exists (see Comparison of online dating services).
Opinions and usage of online dating services also differ widely.
Some sites are completely free and depend on advertising for revenue.
Others utilize the freemium revenue model, offering free registration and use, with optional, paid, premium services.
Such companies offer a wide variety of unmoderated matchmaking services, most of which are profile-based.

However, Sam Yagan describes dating sites as ideal advertising platforms because of the wealth of demographic data made available by users.
