Facebook has 864 million daily active users who are frequently posting photos, writing status updates and commenting on friends' posts.

We may think carefully about what we post on social media — which photos make us look most attractive, what conflict could arise from sharing a particular article — but often the image we try to construct isn't the one people perceive.

Studies show that what we choose to share — and not share — on Facebook is quite telling, revealing aspects of personality and self-image that we might not be aware we're communicating.

Take a look at what your Facebook interactions could be saying about you.

Facebook userVery active user

If you update your status often, always share your vacation photos and are quick to use the "like" button, odds are you're an extrovert. According to a 2014 study, extroverts socialize more on social media, just as they do in real life.

Detailed profile

Open people, those described as creative and imaginative, are most likely to use all of Facebook’s features and fill out their profile thoroughly, according to a study titled "Social Network Use and Personality."

Mr. Popular

People with a large number of Facebook friends tend to have low self-esteem, according to a 2012 study. Researchers found that users with low self-esteem who worried about public perception had the most Facebook friends, and they concluded that these people were compensating by trying to appear popular on social media.

Selfie poster/Frequent updater

If you post a lot of selfies, you likely also make frequent status updates about yourself, which research says is classic narcissist behavior. Narcissists, people with an overinflated sense of self, will make frequent posts — often self-disclosures and self-promotional content — to attract likes and comments that fuel beliefs in their own superiority.

Frequent photo poster

Do you avoid sharing articles on Facebook and shy away from status updates but instead opt to post pictures? According to a 2014 study titled "Capturing Personality from Facebook Photos and Photo-Related Activity," you could be neurotic. Researchers found that people prone to stress and anxiety will often try to express themselves and seek acceptance by posting photos on Facebook. Why photos? They're less controversial than writing comments or sharing articles and are therefore less likely to contribute to anxiety.


Do you make multiple Facebook posts a day? Do you feel like you can be your true self online? Studies reveal you may lack real-life connections and are seeking to fit in online by oversharing in hopes to elicit a response.

Extensive photo albums

Do your albums feature many photos? Are you meticulous in selecting what photos to include? This is another sign of neurotic behavior. Researchers say such Facebook users tend to be anxious and overly concerned with trying to present themselves positively.

Organized photo albums

If you painstakingly organize your albums, putting them in order, tagging the appropriate people and locations, you're likely a very conscientious person. You might not spend as much time on social media as other people, but when you do, it's methodical.

Frequently tagged

Do you often appear in friends' photos, or are you frequently tagged in their status updates? According to a 2012 study, you likely rank high on personality scales for agreeableness. Agreeable people tend to be friendly and less competitive, which is likely why their friends want to take photos with them and share updates with them on Facebook.
