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.

It's an old, established rule, but "golden hour" lighting is ideal because the first and last hours of sunlight are diffuse and warm. For that reason, women with photos taken outside during those hours tended to look great.

Good profiles mentioned characteristics that would probably be true for all of us, such as: "I want someone who will make me laugh." About Me sections with fewer than a hundred words tend to be clearly popular. Short profiles that express just enough information to pique someone's interest work best.

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

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.

Make your initial contact short and sweet. Five sentences or less, or under 150 words. If someone instant messages you while you're online, go ahead and IM them back if you want. Otherwise, wait twenty-two to twenty-three hours between email contacts for the first few messages. Don't send messages while most people are sleeping, even if you're wide-awake. Shoot for business hours or just after dinnertime.
