And some of the tips for men and women are totally different . . .
The ideal photo if you're a GUY is one where you're looking straight at the camera, and smiling without showing your teeth.
But women should do the OPPOSITE . . . look away from the camera and show their teeth.
Guys are twice as likely to have their photo 'liked' if they're looking straight ahead . . . 43% more likely if they're smiling without teeth . . . and 11% more likely if they're the only person in the photo.
Women are 74% more likely to get noticed if they're looking off to the side . . . 76% more likely if they smile WITH teeth . . . 27% more likely to get noticed if they wear their hair UP in the photo . . . and 69% more likely if they're the only one in the photo.
A few things that work on men AND women are artsy black-and-white photos . . . pictures where you're playing a sport . . . and candid shots where you don't look like you're posing.
A few things that DON'T do well with men or women are pictures in sunglasses . . . pictures with crazy filters . . . photos at the beach . . . photos with someone who might be an ex . . . and selfies in general. But especially BATHROOM selfies where you take a shot of yourself looking in the mirror.
