Social Proof: All of Your Questions, Answered

September 27, 2019

Would you jump off a bridge if your friends did? 

This age-old question is rooted in some truth. If my friends all jumped off a bridge and rated the experience as 5 out of 5 stars, I’d do it. Seriously, I would. And I’m not alone in this scenario. In fact, 72% of customers don’t take action until they’ve read reviews, even when these reviews are from complete strangers. 

Staggering facts as such prove the value of using social proof to drive sales in anything from your e-commerce shop to your brick-and-mortar store. 

In this article, we’ll cover what social proof really is, the types of social proof, and some examples of social proof so you can start implementing it into your business strategy. If you’re here for some specific information, jump ahead using the links above. 

What is social proof? 

People want to be reassured when making a purchase. It’s simple as that. If someone else used a product or service and hated it, then you’ll know to avoid purchasing that product or service. 

You can have the best product, the most prepared sales team, and incomparable customer service specialists, and still be missing your goals. That’s where social proof comes in. 

Social proof pushes consumers from a lead to a sale. It influences shoppers in ways that are impossible for a brand to do through traditional advertising campaigns. 

Tip: Social proof and bandwagon advertising go hand-in-hand. Learn how to use them both to improve your marketing strategy.  

There are five types of social proof that you can use to drive sales. Choosing one depends on your budget and available content, like reviews. 

Types of social proof 

Think about your target audience when choosing a type of social proof to implement. Are they the type of people that will buy anything a Kardashian endorses, or are they skeptical and more trusting of a close friend? Insights like these will inform your decision. 


Ah, the power of the crowd. This type of social proof usually uses numbers to show either the number of reviews, users, or followers a brand has. If these numbers are high, use them on your website and marketing campaigns. No one wants to miss out on something thousands of people love.  


This is one we’re all too familiar with. It’s when a celebrity either appears with the product on social media, mentions the product in an interview, or is in advertisements for the product or service. Be sure when using this strategy to be wary of making false claims and know the difference between libel and slander

The wisdom of your friends  

Leveraging the wisdom of friends is a difficult tactic, but once mastered, it has high conversion rates. You can do this by increasing your number of social media accounts, because if someone sees that a friend liked or shared something from a brand, then they are more likely to check it out. Use all of these metrics to create user-generated content


Experts are also a very trusted source. This is why Aveeno says they are the #1 dermatologist-recommended lotion. Expert social proof is most important for medical products or services, but can also be useful for anything that needs more explaining.
