The Power of Social Proof: Why Your Business Needs It in 2025

Humans crave real human experiences. Although the internet is changing rapidly, with generative AI transforming the way we find and interact with online content, people are still reading reviews and looking to social media for real, tangible human perspectives.
And what do user reviews and social media posts both have in common? They both fall under the umbrella of social proof: two words you can’t afford to ignore if you’re trying to grow an eCommerce business in 2025.
In this article, we’re going to explain why that is – and tell you all you need to know about incorporating social proof into your marketing strategy.
Scientist and author Dr. Robert Cialdini can take the credit for coining the term ‘social proof’ in his 1984 book Influence: Science and Practice, but the phenomenon is likely as old as the human race itself. Social proof describes the inherent human tendency to take the path of least resistance and follow the crowd, making decisions based on what the majority of other people are doing.
What device are you reading this on? Maybe it’s an iPhone, an Android phone, a tablet, a PC, a Mac? Whichever applies, it’s unlikely that you’ve chosen that device based solely on technical specs, price, size or any other metric. You’ve probably picked it because you’ve seen others using it, or it’s been recommended to you.
The same goes for the car you drive. Perhaps all your neighbours ditched their hatchbacks for new SUVs a few years ago, so you decided to do the same. And when you grab the keys to go and get a coffee, do you go for an unknown, independent place or a chain like Costa or Starbucks? Probably the latter – because it’s familiar and popular. You can trust it.
Whether we realise it or not, social proof is all around us. As I write this on Google Docs, I’m aware that I was influenced by social proof; Docs became my writing tool of choice because people I worked with were using it. They were more experienced than me, so I trusted their viewpoint and made the switch.
Although we’re all influenced by social proof in one way or another, as marketers, we can also flip the coin and use it to our advantage. In fact, social proof could be one of the most powerful marketing tools out there.
UGC includes anything that has been created by third-party individuals – customers who have used your products and decided to share their opinions about them online. Think on-site product reviews, Google business reviews, social media posts, and even YouTube videos.
Although UGC is mostly outside of your control, it’s important to embrace it as a business. People who haven’t shopped with you before will go looking for others’ opinions, so you might as well make them easy to find. Showing product reviews and social posts on your site (or social feeds) is a great way to build trust with shoppers and give them the confidence to hit the checkout button.
How many times have you visited a website and seen phrases like ‘award-winning’ or logos of the various certifications a company has? Tonnes. The thing is, though, these simple tricks work.
Not only are they good at fulfilling Google’s E-E-A-T guidelines, they tick a little box in our subconscious, telling us that a company is legitimate and trustworthy. So if you’ve got any award wins or certifications to shout about, you should shout about them.
Good, old-fashioned word of mouth is still alive and well in 2025 – and it’s not going anywhere. If you can leave a good enough impression on a customer that they feel compelled to tell their friends and family about you, you’re winning – it’s like a free referral.
Of course, there’s no way to guarantee or track personal recommendations. The best way to make sure you get them, though, is to focus on the customer experience you offer across all your channels, from email to social and everything in between.
If a news site, magazine, or any other media outlet covers your products and says good things about them, that’s another win from a social proof perspective. Let’s say a site like Which? reviews a load of fridges and your brand emerges victorious – that’s a huge trust signal for customers.
Even if they’ve never heard of your brand before, they might be willing to take a punt on one of your products if they come recommended by an expert.
This is one form of social proof you have complete control over, from start to finish. Particularly if you run a B2B brand, case studies are the perfect way to demonstrate your expertise in a way that feels authentic and natural – not pushy or forced.
Any time you build a successful relationship with a client, take the opportunity to write about that and get some feedback from them. Add some data into the mix and some stylish photos, and you’ve got yourself a powerful marketing tool.
Once you’ve created your case study, share it on your emails and social channels for maximum impact.
This is a particularly satisfying one. If you manage to create a best-selling product, you can use this as social proof to persuade even more people to buy it. Authors do this all the time, labelling their best-selling books as just that – and compelling people to pick them up. After all, if so many people have bought the book, it ought to be good.
Amazon also uses this to its advantage, labelling products as best-sellers within specific categories. Once customers see that label, they click – and then the user reviews and product content do the rest. That’s a great example of social proof not only hooking customers and pulling them in, but convincing them to make the purchase.
What’s the biggest barrier that prevents a customer from converting on your site? Often, it’s a lack of trust in your brand – simply because they haven’t heard of it before. People don’t just want to hand over their hard-earned money without making sure they can trust your business first – and social proof is instrumental in building that trust.
Let’s face it: positive comments from customers, the press and anyone else that cares to make them will only be a good thing for your brand. Social proof can really help cement your brand as an industry leader, giving you the perfect foundation to grow in the long run.
If you’re using social proof to your advantage and your rivals aren’t, you’ve immediately got a competitive edge over them. And when you consider just how saturated the world of eCommerce is nowadays, any ‘edge’ you can get is tremendously valuable.
Social proof doesn’t just help drive traffic, it can lead to soaring conversion rates. Things like on-page product reviews, award-winning icons, and accreditation logos can drive conversion rates through the roof, making them a must-have.
Social proof can be used on every channel, including email marketing. Sharing your latest case studies, reviews and UGC with your customers can help keep them engaged with your brand, building loyalty month after month.
