You see, when a friend or family member recommends a product, you’re more likely to take their endorsement seriously. In fact, Nielsen reports that the most meaningful form of advertising is recommendations from friends and family: 83% of consumers in 60 countries say they trust these recommendations over any other form of advertising.
The story of how I bought my mattress is a great example of social proof, which refers to the theory that people tend to adopt the opinions or actions of people they trust. And to help illustrate how brands are using this persuasive technique in their marketing, we’ve put together a roundup of social proof in action below.
What Is Social Proof?
Social proof is the idea that consumers will adapt their behavior according to what other people are doing. It makes sense, right? When we see a line of customers waiting to eat at a restaurant or a photo of a celebrity drinking a certain brand of coffee, it lends an air of gravitas and quality to the product, doesn’t it?
But there’s more to it than that. In fact, according to Buffer, there are actually five different types of social proof:
1) Expert Social Proof
Expert social proof is when an industry thought leader or influencer approves of your product. This could take the form of them blogging, posting on social media, or being quoted or photographed as a product user.
2) Celebrity Social Proof
Celebrity social proof typically takes the form of a celebrity using a product and promoting it on social media or in public. This form of social proof is especially meaningful if the endorsement is unpaid.
3) User Social Proof
User social proof consists of positive feedback from actual users, typically taking the form of customer reviews and testimonials.
4) “Wisdom of the Crowds” Social Proof
5) “Wisdom of your Friends” Social Proof
“Wisdom of your Friends” social proof refers to the phenomenon I described previously: The recommendations from people we know and trust carry far more weight than other types of promotions or advertising.
Which Types of Social Proof Work Best?
The (social) proof is in the pudding: Social proof in your marketing and advertising can have a huge impact. But what type of social proof works best?
While this will likely depend on the product or service you are marketing, the folks at ConversionXL conducted some research to help shed some light on the situation.
Below you’ll find some noteworthy statistics from their research about the types of social proof that perform best, and what you need to know about convincing your prospective customers:
- Testimonials featuring photos perform best.
- Readers remember press mentions featuring company logos more than press mentions featuring quotes.
- Prominent client logos in testimonials are highly memorable.
- 86% of female shoppers say they put the most trust in product recommendations from real people — either industry bloggers or people they know — more than celebrities.
- 66% of consumers trust customer reviews online.
- 60% of consumers prefer to make purchases from brands they are familiar with.
- 77% of consumers say that word-of-mouth from family and friends is the most persuasive way to get information about new products.
- Excessive negative customer reviews in Google Search results can result in a loss of up to 70% of potential customers.

Fitbit lets health and tech industry experts speak to the quality of their products in the “Buzz” section of their website.

Gwyneth Paltrow is a longtime fan and friend of Tracy Anderson and her exercise program, which she frequently posts about on social media.

I had never heard of Manuka honey until I watched this episode of Broad City, but it exploded in popularity after Kourtney Kardashian started using it on her reality show, and then became a celebrity ambassador. This is a particularly successful celebrity social proof because Kardashian’s longtime use of the product lends more authenticity than a celebrity endorsement alone would.

Customer reviews and testimonials are one of the strongest forms of social proof, and Amazon provides another great example of how they can be used. In their review sections, they publish the breakdown of the different ratings so visitors can easily see if the majority of purchasers were happy or unhappy with what they bought.
Customers can also publish reviews with specific comments and photos of their purchases, which are more eye-catching forms of social proof for visitors than testimonials alone.
13) G2 Crowd
G2 Crowd is a business built on user social proof: It offers businesses a database of reviews and recommendations before making a software purchase. The reviews feature verified users of the product, their LinkedIn career information, and the logo of the product being reviewed, which is a research-backed strategy for promoting greater viewer recall and retention.
Here’s a thorough example of user social proof from BuzzSumo. Their website features customer testimonials and case studies so visitors can read about the full story behind the product they’re considering without any question of its impact on real customers and organizations.

Netflix takes advantage of user trends by suggesting new TV and movie options based on popularity. This clever use of social proof helps them keep people binge-watching instead of navigating away when they finish a movie or season — a great retention strategy, if you ask me.
Much like when things are trending on Twitter, trending suggestions aim to pique the interest of users and persuade them to tune in.
