eHarmony is where relationship-oriented daters love to go, as the site is responsible for 4% of U.S. marriages. Co-founded by clinical psychologist Dr. Neil Clark Warren, eHarmony is probably most known for their exclusive 29 Dimensions® of Compatibility test — which is composed of four categories: Character and Constitution; Personality; Emotional Makeup and Skills; and Family and Values. For no cost, you can fill out your information, take the questionnaire, and receive like-minded matches.
The site has profile verification options to ensure you are matching with real people and not fake profiles. On top of that, the site has a Smart Match system that essentially allows it to learn your preferences the more you use it, and the option to send a “Mega Flirt” that reaches dozens of inboxes every 15 minutes. It's a site you won't easily grow bored of that aims to help you become a better dater.
