eHarmony is a dating site that does away with online dating norms. Instead of letting you search for specific partners, they utilize a custom 29 Dimensions® of Compatibility personality test to match you with prospective dates. The formula has had success, as the company claims to be responsible for more than 400 marriages a day.
eHarmony matches you with like-minded people. The test is comprehensive and lengthy, ensuring that many of your likes and dislikes match on many different personality levels. The website also asks your preferences regarding smoking, drinking, religion, politics, kids, etc., ensuring good matches.
No search function. Instead, they match you. They also do not show you any pictures at all until you pay. That part turned me off a little. I'm also one who prefers to search my own parameters instead of being matched, but that's more me – you may feel different.
The cost is on the higher end (but not too high), which I'm sure is what they want to keep their user base on the serious side. 3 months for $59.95 per month (and 6 @ $41.95 per month, 12 @ $21.95 per month.) As stated, you cannot see any pictures without paying.
eHarmony is a serious online dating site for people looking for a serious relationship and/or marriage. I wish they would show you pictures with a basic signup, but otherwise, it's a solid dating site. They boast a lot of marriages, so it must be working, and is worth checking out if you are looking for more than simple dating.
