Tinder reveals science behind online dating

WEST HOLLYWOOD, Calif. -- Tinder's top expert revealed details on the science of matching in online dating and the key ways to attract a potential date.

For so many people today, dating is largely defined by swiping. The dating app Tinder pioneered the concept.

If you both swipe right, signifying you like each other, you can start chatting, and experts say that is why profile pictures can be one of the most important factors in online dating.

Officials from the West Hollywood-based mobile app say there's a science behind swiping, and Dr. Jessica Carbino is their in-house sociologist.

"Individuals are looking for a lot of different signals and cues when they're analyzing photographs," she explained.

So what makes for a good profile picture? Some of the dos and don'ts might be surprising.

Carbino recommends not to wear accessories that cover up your face, including hats and sunglasses

Neutral colors are also not recommended for an eye-catching profile photo. Experts suggest to wear something bright and have at least one picture with a formal outfit.

People tend to respond to pictures with animals and traveling shots, but the most important advice? Smile.

"Always smile because people who smile are considered to be kind and approachable," added Carbino.

Once you do match, Carbino said asking questions is the best way to keep the conversation going.

"When I was single and dating, I used to ask people, 'What's your favorite place to travel to?' And people would often answer my question. So if you provide people with fodder for the conversation, you can have more success in the future," she said.

Although some still resist mobile dating, the growing popularity is extraordinary. Tinder officials said they now see 26 million matches every day, resulting in 11 billion matches since their launch.
