How it works: Like a good wingman (or wing woman), Zoosk starts to understand you more and more as time goes on to help introduce you to the person you can spend the night or rest of your life with. The site's unique algorithm recognizes your preferences through the actions you take. The more you interact with the site, the better it can match you with your ideal human.
Match.com: If online dating was boxing, Match.com would be in the heavyweight category. It is a site that has a large number of members, longevity, site functionality and pricing options. I used this site for two years while I was living in New York and had quite a few dates. Unlike eharmony though, I spent a lot more time weeding through lower quality profiles.
