How To Use Social Proof in Digital Marketing?

What is social proof?

Social Proof is a phrase coined in 1984 by author Robert Cialdini in his book Influence. It is the idea that people try to emulate others by doing things to mimic their behavior. In marketing, social proof relates to a similar idea. Social proof is one of the principles described by Robert Cialdini in his groundbreaking book. It works on the principle that an undecided person makes a decision (sometimes adopts a view) the same as the majority of the group.

Using a simple example, it looks like this: a person faced with the choice between an ice cream shop with people and an empty one is more likely to choose the one where there is a queue.

Customer reviews are typically very short snippets of descriptive text written by customers about products. You can ask for reviews via the Product Page or contact your consumers via email to request their feedback. By including microformats, you can easily see the reviews in the Google results.

Using influencers in digital marketing is an example of using social proof. Viewers follow these influencers because they’d like to see what kinds of products and services the people wear, use, and love. Companies use influencer marketing in the form of collaborations, PR packages, or in the form of barter.


Another form of social proof is integration. These typically include SaaS tools that want to make it convenient for their customers to use different services they are already using. Also, it makes the users want to try the other platform and become a customer. For example, Calendly integrated with Slack. Calendly tweeted about their new integration, and later Slack retweeted the post.


Affiliations are a simpler form of social proof, and you can usually get them without asking for them directly. This is when your company is associated with some other business, person, or organization.

An example of social proof is to show the logos of publishers with high authority on your website. You can also include trust badges, so users feel more comfortable at your business.


Showcase real-time data. The most effective forms of social proof–showing your visitors how many other users are viewing the page, purchasing the product, or sharing it on social media–may noticeably increase FOMO. You can also do this to demonstrate the number of products sold, clients served, etc.


If you have a large customer base, mention the size of your customer base in your profile bio. For example, “Veronica Maxwell used our product and saw an increase of 37% in conversions”. When people see that many people are using your product, they would likely have a positive first impression of your product.
