Why Do We Like, Comment, and Share on Social Media? – Best Marketing and Lead Generation Agency

Our online habits—liking, commenting, and sharing—are not random. We like posts to show our interests, comment to get noticed or feel validated, and share to connect with others or be part of something bigger.

For brands, influencers and indivisuals, understanding why people engage can make all the difference. When content taps into what people care about, it feels more relatable and encourages real interaction..

Here’s a closer look at the key factors influencing our social media interactions:

Social Validation: People are social animals at heart, and they want for other people’s acceptance and acknowledgement. This approval is instantaneous and very noticeable on social media.
Example: A girl posts a picture of herself wearing brand-new clothing on social media, writing, “Loving this new look for fall!”
Followers engage with likes, comments such as “You look amazing!” and “Where did you get that outfit?” This validation affirms the user’s style choices and encourages them to post more fashion-related content.Here’s a closer look at the key factors influencing our social media interactions:

The Reciprocity Principle: Give-and-Take Relationship
Example: An Instagram influencer posts a photo of a new beauty product they are promoting, with a caption asking followers to share their favourite ways to use the product.

Follower Interaction: Followers comment with their thoughts and experiences, such as, “I love using this product for my morning routine!”

Influencer’s Response: The influencer replies to these comments with personalised responses like, “Thank you for sharing!

Impact of Reciprocity:
- Feeling Valued: By responding to comments, the influencer shows appreciation and makes followers feel valued.
- Increased Engagement: Followers who receive replies are more likely to continue engaging with the influencer’s posts in the future. They might comment more, like additional posts, or even share the content with friends.

Emotional Resonance’s Power
A lot of our conduct on social media is motivated by our emotions. Whether it be joy, rage, grief, or excitement, content that evokes strong emotions in people increases their likelihood of being engaged.

Example: A user posts a photo of a rescued dog with a caption telling its story, like “Meet Max, who was saved from a shelter and found his forever home!” The photo shows Max looking happy and loved in his new home.

Content: The post tugs at heartstrings by showcasing Max’s journey from a shelter to a loving home, evoking emotions of joy and compassion.

Engagement Results:

High Engagement: The post receives many likes and comments such as, “So happy for Max!” and “This made my day!”
Sharing: Many users share the post to spread the heartwarming story with their friends and family.

Social Proof: The Engaging Herd Mentality

A psychological phenomena known as “social proof” occurs when people use other people’s behaviour as a guide for their own behaviour. We are more inclined to interact with a post when we notice that it has received a lot of likes, comments, or shares.

Example – Imagine you’re scrolling through Instagram and come across two posts—one has only a few likes, while the other has thousands of likes and hundreds of comments. You’re more likely to interact with the second post, even if the content is similar. Why? Because the high level of engagement signals that it’s popular and worth your attention.

The Dopamine Effect: Engagement as Instant Gratification

Social media platforms are built to keep us coming back for more, and they do this by triggering the release of dopamine, the brain’s “feel-good” chemical. Every time we get a like, comment, or share, we experience a quick hit of pleasure. This instant gratification keeps us hooked, reinforcing our desire to engage again and again.

Example – Say you post a picture on your feed or an exciting story update. Right after, you notice the first like or comment—it feels satisfying, right? That’s dopamine working, giving you a small but instant rush of pleasure. As more likes, comments, or views come in, the dopamine hits keep happening, creating a cycle where you keep checking your phone for more.

The Desire for Self-Expression
Social media gives us a platform to express who we are. Every time we engage with content by liking, commenting, or sharing, we’re sending signals about our tastes, values, and beliefs.

Example – When you like a post about a new fashion trend on Instagram or comment on a funny meme, you’re sharing a part of your personality. Your interactions reflect your sense of humour, style, or opinions. Even the photos you upload, the captions you write, and the stories you post are all ways to communicate who you are to the world.

Understanding these psychological factors reveals why we engage with social media the way we do. From seeking validation and expressing ourselves to responding to emotional content and social proof, our interactions are shaped by a complex mix of desires and rewards. For brands and influencers, tapping into these motivations can lead to more meaningful engagement and stronger connections with their audience. In a crowded digital world, leveraging the psychology behind social media interactions is crucial for creating content that truly resonates and makes an impact.
