What is Social Proof?

Social proof or informational social influence is a term that refers to how people adapt their behavior at a specific time to simulate what other people or groups of people do.

In marketing, it is a strategy used to give confidence to potential customers who will imitate their behavior by observing the recommendations and actions of others for a product or service.

What are the types of Social Proof?

There are many types of Social Proof that influence consumers' decisions, among the most used are:

Celebrity

Celebrity social proof happens when a celebrity such as Tom Hanks or Elon Musk, among others, recommends a particular product or service with a Twitter message, Facebook story, etc.

Expert

Expert social proof happens when an expert in a specific area suggests using products or services related to a brand.

Wisdom of friends and crowd

Happens when a group of people, friends, or a crowd recommend a product or service.

User

User social proof happens when your website’s users recommend your brand or products, e.g., by writing reviews, positive comments on the website or on social networks, etc.

Certification

This type of social proof happens when an authorized body endorses your product or service by giving it a seal of approval.

Why is Social Proof important for online marketing?

When people shop in a store they can touch the product, try it out and compare it better, unlike those who shop online.

The former receive little external influence to make a decision. However, a study indicates that at least half of them currently check their mobile device to know others’ opinions before doing so.

On the other hand, in online shopping, it is generally necessary to review external opinions to make a purchase decision, to know if the product or service is of good quality, if it has the right color, size, if it works correctly, etc.

For example, if a person is going to buy lipstick and more than three million people have bought it and liked it, likely, this person will also like it.

In digital marketing, the strategic use of social proofs is crucial to succeeding in campaigns because apart from guiding consumers to buy a product or service, it conveys confidence and credibility to provide their data, which translates into more conversions.

What is an example of Social Proof in marketing?
