Social proof is the idea that people are more likely to take action based on the actions of others. It is a type of psychological phenomenon that occurs when people observe the actions of others and use those actions to guide their own behavior.

There are several different types of social proof, including expert social proof, celebrity social proof, and user social proof.

Examples of Social Proof in real life

One common example of social proof is when a product has a lot of positive reviews. Seeing that other people have had a positive experience with the product can influence someone’s decision to purchase it themselves.

Another example is when a restaurant is crowded. Seeing that a lot of people are eating at a particular restaurant can make it more appealing to potential customers.

A personal example for social proof: It’s not long ago that I went to a large supermarket with a wide range of oils. I was looking to buy an oil with a neutral taste to cook meat in the pan. However, I found myself overwhelmed by the variety of oils and couldn’t decide which plant oil to purchase. In my dilemma, I noticed a woman taking a particular oil, and I decided to follow her lead.

Examples of Social Proof for websites and online businesses

The importance of social proof for online businesses cannot be overstated. It can help to increase conversions, drive more sales, and build a loyal customer base. Here are a few examples of how social proof can be used in online businesses:

Customer reviews and ratings

By displaying positive customer reviews and ratings on your website, you can show potential customers that other people have had positive experiences with your business.

Social media interactions

If your business has a large following on social media, this can act as social proof that many people are interested in your business and find value in your products or services.

User-generated content

Encouraging customers to share pictures or videos of themselves using your products can be a powerful form of social proof. Seeing real people using your products can help to build trust and credibility.


A testimonial is a statement from a satisfied customer who has agreed to share their experience with others. They can be used to show that other people have had positive experiences with your business.

In summary, social proof can be an extremely powerful tool for online businesses, helping to build trust and credibility with potential customers and ultimately drive more sales.

FAQ about Social Proof Who discovered „social proof“?

The concept of „social proof“ was first introduced by psychologist Robert Cialdini in his book „Influence: The Psychology of Persuasion.“ In the book, Cialdini explores various psychological principles that influence human behavior, and social proof is one of the key principles he discusses. Cialdini’s research and observations shed light on how people tend to look to others for guidance and validation, especially in situations where they are uncertain or unsure about what course of action to take. Since then, social proof has become widely recognized and applied in various fields, including marketing and advertising, to build trust and influence consumer behavior.
