When it comes to online dating, your profile pictures are crucial. They are often the first thing potential matches see and can greatly influence their decision to swipe right or left. But what makes a good dating app photo? According to science, there are certain characteristics that can make a photo more attractive to potential matches.

1. Show your face: A study published in the journal "Personality and Individual Differences" found that profile pictures that show a person's face are more attractive than those that don't. This is because a face can convey a lot of information about a person, such as their age, gender, and even their personality.

2. Smile: A study published in the journal "Social Psychological and Personality Science" found that people who smiled in their profile pictures were more likely to be swiped right on than those who had a neutral or serious expression. This is because smiling is seen as a sign of happiness and positivity, which are attractive traits.

3. Show off your interests: A study published in the journal "Computers in Human Behavior" found that people who included photos of themselves participating in activities they enjoy, such as hiking or playing an instrument, were more likely to receive messages than those who didn't. This is because these photos give potential matches an idea of what you like to do in your free time and can spark a conversation.

4. Use high-quality photos: A study published in the journal "Computers in Human Behavior" found that people who used high-quality photos in their profiles were more likely to receive messages than those who didn't. This is because high-quality photos are more visually appealing and can make a person appear more attractive.

5. Show your personality: A study published in the journal "Computers in Human Behavior" found that people who included photos that show their personality, such as silly or candid photos, were more likely to receive messages than those who didn't. This is because these types of photos give potential matches a better idea of who you are and can make you seem more approachable.

   In conclusion, science suggests that when it comes to dating app photos, showing your face, smiling, showing off your interests, using high-quality photos and showing your personality can make you more attractive to potential matches. So, next time you're updating your dating app profile, keep these tips in mind to increase your chances of finding a match.
