Social Proof: Definition, Purpose & More

Everyone uses it, but what does social proof really mean and how important is it for businesses? Find out here!

Each of us wants to be sure before making a decision and make the best choice. Sure, that’s human. But did you know that this need is so deeply rooted in us that it even influences our behavior? In this article you’ll learn all about Social Proof and why it’s so important.

Social Proof Definition


Social proof is a concept that says people are more inclined to do things that other people do. It is a phenomenon that has long been known in psychology and is known by various names, including conformity, social norms, and hearth behavior.

A study by Robert Cialdini and his colleagues has shown that social proof is one of the most powerful tools to influence people. In the study, participants were asked to imagine that they were standing in a queue at a photocopier. The researchers asked the first person in line to either sit or stand, whichever they thought was appropriate. Then the next person was asked to do the same. The results of the study showed that the people whose turn it was were more likely to sit or stand if the person in front of them had done the same. Social Proof can be applied to many areas of human behavior and is particularly useful for companies and organizations that are trying to encourage certain behaviors. For example, companies can show their customers that other people are buying or using their products to get them to do the same. Organizations can also use social proof to persuade people to take certain actions, such as donating to charities or taking environmental action. So social proof is a very powerful tool to influence people. However, organization- and enterprise-specific applications should be used judiciously. For example, it may be ethically questionable to use social evidence to promote products or services that are potentially harmful to people’s health or safety.

Social proof can be applied in many areas. Some examples are:

Advantages of Social Proof

There are many benefits associated with the phenomenon of social proof. First of all, it can help us feel more comfortable in our environment and adapt better. When we see other people doing something, we often feel more motivated to try it ourselves. In addition, it can also help us make decisions. When we feel unsure of what to do, we can look to others for guidance and see what they are doing. In this way, we can more easily decide whether to do something or not.

Disadvantages of Social Proof

Social Proof is not perfect and also has some disadvantages. These include:

  1. Social proof can be easily manipulated.
  2. People can be influenced by social proof, even if it is inappropriate.
  3. Social proof can lead to group thinking rather than individual thinking.
  4. Social proof can lead people to do things they don’t really want to do.

Why is social proof important?

Human nature is to align with the group. So when other people validate or support our decisions, we tend to judge them as correct and beneficial as well. This phenomenon is called social proof and can be applied in a wide variety of areas of daily life – from marketing to education to politics. In the age of the Internet and social media, social proof plays an even greater role than before, as opinions can be quickly shared and spread.

The goals of Social Proof


The concept of social proof can be applied in advertising and other areas to influence people. The goals of Social Proof can vary depending on who is using it. It can be used, for example, to:

  • Getting people to buy products or services;
  • Influence people’s views about certain topics or people;
  • Getting people to stand up for or against something;
  • Build the reputation of a person or organization. When used correctly, social proof can be very powerful and have a big impact.

How important is social proof for marketing?

In our daily lives, we see examples of social proof all the time: if you’ve ever tried to watch makeup tutorials but got confused because of all the negative comments, you’ve almost certainly asked yourself, “Is it really worth wasting my time watching this video?” This is a classic example of social proof in action. People are negative about something, so they tend to take the same attitude. People’s herd mentality allows entrepreneurs to market their product or brand and reduce associated costs. When customers see that other people love your product and recommend it in conversation with friends, they are much more likely to try it too.

Types of social proof

  1. Herd instinct: The human instinct is to join a group and go with the crowd. When we see others doing or having something, we tend to want it too or believe it is right. This need to belong is strong and can motivate us to buy certain products or strengthen our belief in a cause.
  2. Testimonials (personal stories)When people tell us what they think about a product or how it has improved their lives, we listen and believe them. Reviews from friends, family members, colleagues and celebrities are the most familiar form of social proof for many. Statements of this type work best because most people can identify with them – unlike the opinions of strangers. Therefore, it is advisable to include testimonials in your website copy to build trust with potential customers.
  3. Expert opinions: The opinion of experts also has a major influence on our purchasing decisions. When a well-known professional or recognized organization recommends a product or brand, we are inclined to follow that advice. This is especially true if we ourselves are not experts in the field. Again, the better the expert’s reputation, the stronger his or her voice.
  4. Bandwagon effects: The “Bandwagon Effect” simply states, “Everybody does it!” The more people do or have something, the more we also tend to follow this trend – even if we are not even aware that we are victims of this phenomenon. Whether in terms of fashion trends or technology gadgets – as soon as some hype arises, suddenly everyone wants to join in
  5. Reviews: We trust other customer opinions much more than advertising statements from companies. The reviews of other buyers give us an objective impression of whether a product is good or not. It does not matter whether the assessment is positive or negative – the main thing is that it is credible and comprehensible. It is still best if you have had experience with the product yourself or know someone who has (friends/family/acquaintances).

If you’re self-employed or an entrepreneur, you’ll certainly get reviews. It’s not always easy to know how best to respond to comments – especially when they are complaints.

How can companies use social proof?

Companies can use social proof for their marketing purposes and present customer quotes and reviews from users on their website to better sell certain products. When potential buyers see that others (especially trusted group of people) have actually already made the purchase – social proof itself as a means of marketing – this is helpful in attracting new customers.

Truths about the power of social proof

When it comes to purchasing decisions, we prefer to trust the experiences of others. Although the individual may be looking for the best possible value, he or she is rarely objective. Instead, we take our cue from what others are doing and buying. It does not matter whether these people are friends or strangers – the main thing is that their judgment is another opinion leader for our own decision. A lot of business advertising focuses on proving that lots of people are already customers – using testimonials, linking to social media, and reviews. This tactic attempts to exploit our natural aversion to risk and get us to make the same decision as others.


Although social proof has pros and cons, it is ultimately a useful tool to help companies sell their product better. When used properly, social proof can help build customer trust and increase the likelihood that they will make a purchase.
