New Study Reveals the Most Effective Line for Online Dating

What's your best pick-up line to woo a woman when you're flirting online? Do you tell her you love her eyes, face, or perhaps her sense of humor?

According to a recent study by international online dating site Badoo.com, while the phrase "you have beautiful eyes" is the most common opening line men use, the phrase "you have beautiful lips" is actually more effective. This is the same across the globe, no matter the country in which you live.

Badoo.com claims to be the world's largest social dating network, with 87 million registered users worldwide. The site studied 200,000 online flirtations in 10 languages over a one-month period.

Psychologist and dating coach Jo Hemmings, quoted in the study's release, noted that complimenting the lips over the eyes made sense, "because it's bold not cautious", and because it's unusual and seems more personal.

Different countries have their own preferences of course. The study also noted successful pick-up lines in various regions: in Spain and South America, men get responses when they compliment a woman on her hair, in the U.K., complimenting a woman on her legs, and in Portugal, complimenting her ears.

"This is a scientific study of which pick-up lines actually work", says Lloyd Price, Badoo's Marketing Director. "We've found the Holy Grail of flirting."

While different techniques work for different people, it may be worth a try to test this out and see what happens. Generally speaking, the more personalized and unique your compliments are based on what she writes in her profile, the better chance you have of getting a response.
