Has your mother ever said this to you: “If all your friends jumped off a bridge, would you do it too?” Or have you ever felt pressured to buy a specific brand of clothes, a particular model of phone, or a new car just to “fit in” at work or with your friends?
If so, you’ve experienced the power of Social Proof.
What is Social Proof?
Made famous by Professor Robert Cialdini in his book, Influence, Social Proof describes the tendency of people to look to the actions of others to gain psychological permission to try something new. As Cialdini writes, we look to two types of people:
- “Many Others”: Proof that lots of people are using this product
- “Similar Others”: Proof that people we admire, identify with, or are part of our community are using a product or doing something
Social Proof is one of the most effective psychological tactics you can use to persuade customers to try something new. According to Nielson research, 83% of consumers in 60 countries say they trust social proof over any other form of advertising.
Social Proof in the Real World
Consider the case of “canned laughter,” recorded tracks of crowds laughing often used in sitcoms. Everyone hates the sound of canned laughter, so why is it so popular?
“What this study shows is that adding laughter to a joke, increases the humor value, no matter how funny or unfunny the joke is.”
Audiences are feeding off the Social Proof that what they’re watching is funny, so they’re more likely to laugh. But interestingly, the same study found that while canned laughter does cause people to laugh, the sound of a real crowd laughing made a joke even funnier.
How to Apply Social Proof
To apply Social Proof to customer experiences, make customers feel like “everyone’s behaving this way or buying this product, except you.” A few of the ways we can use Social Proof to do this include:
One of the most potent ways to drive sales with Social Proof is by using product reviews and testimonials. According to Mintel research, more than 70% of Americans ask others for their opinions before making a purchase.
The younger the consumer, the more they seek out opinions. 81% percent of 18–34 year-olds look for reviews before buying a product.
2. Stats and Data
Using quantitative Social Proof can help convince customers that they’re in safe hands with your product in the form of numbers. A classic example of using data as Social Proof comes from McDonald’s, which posted how many people its crew had served for years.
After a while, McDonald’s had so many points of Social Proof that it had to keep changing its signs. Eventually, it amended every store sign to permanently read “Billions and Billions Served.”
3. Designate Best Sellers
Studies have found that simply indicating an item is a best seller or “most popular” can help increase sales. For example, researchers studied the ordering habits of diners restaurants in Beijing, China. They found that simply labeling a product “most popular” could raise sales by 13% –21%.
4. Use Quotes and Verbatim
When people similar to ourselves endorse or use a product, we’re more likely to believe it will work. And if that person is a trusted member of our community, even better.
Three Examples of Brands Using Social Proof
1. Everlane: Using reviews to drive business
Everlane, an online clothing retailer, uses reviews to encourage customers to try its products. These reviews can help customers find the approval of the crowd before trying something new.
2. The Body Shop uses data to convince customers their lotion is iconic
The Body Shop, a beauty and cosmetics retailer, relies on data to get more users to try its Hemp Hard-Working Hand Protector. By telling customers that a tube is sold every 9 seconds, they’re calling on the “many others” as a proof point for their claim that the hand cream is “iconic.”
3. Zapier uses testimonials from “similar others” to drive trial
Zapier, the automation platform, uses the power of “similar others” to gain new users. Their copy even references “people like you” over real customer quotes, creating a potent combination of Social Proof triggers.

The bottom line
According to research firm Nielsen, Social Proof is one the most effective marketing tactics. The best part about it? It’s relatively easy and cheap to implement. You just have to reframe your marketing messages using Social Proof messages. To apply Social Proof ask yourself:
- What are the risky moments in our experience? Can we include a social proof message to minimize the risk?
- Are there certain products customers might be willing to try if the risk were lower? Can we normalize the use of this product with our potential customers’ social group?
