Popular women use positive, optimistic language in their online profiles, not buzzwords like "future thinker". Here are the ten most often used words I found: easy-going, love, laugh, laid-back, optimistic, outgoing, fun, down-to-earth, pleasure, adventure.

Most people don't wear glasses in the U.S., and we're not conditioned to finding men and women who wear glasses sexy. If you need your glasses to see, find a good optometrist who can outfit you with a great frame, thin lenses, and a high-quality anti-reflective coating.

The goal of online dating is to get offline as quickly as possible.

If you're trying to cast the widest possible net to attract the largest selection of men or women, the last thing you should do is to start listing your income, political views, and the like. Avoid mentioning specific comedians, shows, or movies unless those are top-tier attributes on your list.

Photos should focus on your waist up, unless you have amazing legs. Then it's okay to include one or two full-body shots in your gallery. The majority of your photos should be closer up, highlighting your face. Don't stage a smile. Instead, try to laugh just before the shot is taken. Flirty smiles that don't look cheesy also work. Make eye contact with the camera. Aim to take most of your photos outdoors.

Peak hours for sending a first email through the online dating system tended to be during work (eleven A.M. to four P.M.) and then just after dinner (seven P.M. to nine P.M.). I did have a few women send me a first message after eleven P.M. Those who did had an 82 percent chance of coming from a profile that had too many words.

If you want true love and a long-lasting marriage, you need to start by figuring out what makes you happy.
