According to a study by the online dating site Zoosk, you should make sure that your face is visible and that you have uploaded at least one full body picture to maximize your chances of your profile being viewed. Business Insider is reporting that "Full body shots yield positive results for both sexes. Those who use full body photos see a "203% boost in messages received." When it comes to using a selfie, woman should use them because they will receive more messages, while men who use them will receive less.
