Top 5 Online Dating Sites

Yahoo Personals is a good place to start. It's got over 9 million members, tons of pictures, and a free 7-day trial period. There are also tips and guides on how to flirt online or survive a broken heart.

Match.com is also a very highly rated site, and claims to be the world's largest online dating personals service. I'm not going to argue with them. Plus, it's Dr. Phil-sanctioned.

From what I've heard, the success rates from this site are very high. Members are pre-screened and there's a lot of personal attention. A con: it's not available in all areas.

eHarmony is a really trustworthy site that matches couples based on compatibility and I've heard a lot of success stories. They also offer a new service for married couples to enhance their relationships. Plus, your personality profile on eHarmony is free.

Perfectmatch uses a scientific matchmaking technique called Duet to find compatibile singles. It's also endorsed by more leading scholars. Compatibility profiles are free here, too. It also gives you the option to search, in case the matches Duet gives you aren't quite right.
