If a success story is your number one concern—your main goal, in fact--when choosing a dating site, a site like eHarmony is probably more up your alley. The site was created in part by a psychologist who believed that certain traits could predict compatibility in relationships. He set out to test this theory and voila, eHarmony was born. As you might expect from that origin story, the site is marketed toward (straight) people who are looking for serious relationships. And on that note, this site uses serious tools to make that happen. Many sites have matching questions to help narrow down a user's potential suitors. eHarmony, on the other hand, requires the use of a proprietary questionnaire with a staggering number of (again, required) questions to make matches. Serious tools for serious people. These questions promise to get to the heart of who you are and what you're looking for and if all that self-analysis isn't enough, the site also offers a free, optional personality profile after you complete the questionnaire. Don't worry, though—the profile will put a sweet spin on even your most negative traits. Selfish? No! You're fostering independence.
However, an estimated 20% of users complete the Herculean task of answering a reported 258 questions (down from 436!), only to be told that they are adrift, alone, unmatchable. No man is an island, but a fourth of eHarmony potential dates are, according to the site's magic. Sorry, John Donne. So what makes you a love pariah according to the machinations behind eHarmony? According to reports, the site has issues matching the already married, which is unsurprising, but also the previously married. In addition, if you have had chronic issues with depression and possibly other mental illness, you are going to be out of luck on eHarmony. The other big problem for the questionnaire? Anything outside of heterosexuality. This last point, in fact, led to a discrimination lawsuit against the site. As a result of that suit, users looking for same-sex relationships are now funneled toward eHarmony's sister site, Compatible Partners. Catchy name, isn't it?
But if you're straight, unmarried, blessed with perfect mental health and the patience to answer all those questions, eHarmony will (likely) start spitting out possible partners as soon as you're finished. According to them, there's a high probability that good things will start happening after that because they claim to be responsible for 4% of all US marriages. (That data is based on a survey they commissioned, though, so of course, your mileage may vary.) Like Zoosk and other sites, though, they have a list of success stories. Whether you'll be one of them, they of course do not guarantee. However, if you pass the questionnaire and still have no luck, there is also EH+, their service that functions like a personal matchmaker.
EH+ is not complimentary, obviously. Costing at least $5000, this is the most serious tool in their toolbox. As with the regular site, they don't guarantee happily ever after, but they do guarantee that you will shown high-quality matches with whom they believe you're compatible. If that sounds great, but you're reeling at the price, you might be better off with the regular site and service, which costs around $60 a month, although they do offer specials. The site also has an app (available in iOS and Android), which features a pared-down version of that questionnaire with only 100 questions.
The final word: If you're very serious about finding a committed relationship, eHarmony's the site for you.
