There’s one surefire way to boost trust in your brand and get those sales flying – social proof. Get to know the different forms of social proof and how to use them to build your business.

In the psychology of persuasion, the phrase โ€˜social proofโ€™ refers to the way other peopleโ€™s actions guide our own. Hereโ€™s how you can use social proof to increase your sales and brand trust.

Forms of social proof – and how to use them

1. Generate trust through testimonials

When someone else writes positive comments about you and your business, it sends a strong message that you can be trusted. Prospects are afraid of wasting their time and money doing business with someone they donโ€™t know or trust; but testimonials generate trust through social proof.

People think, โ€˜If Joe Bloggs got great results using Tomโ€™s service, then I want to use Tomโ€™s service tooโ€™.

Thereโ€™s no doubt that client testimonials win customers.

Donโ€™t restrict yourself to written testimonials, either. One of my clients has recently experienced a marked increase in daily enquiries due, in part, to placing video testimonials on her home page. Why the increase? Because social proof is powerful.

2. Win business with word of mouth and referrals

As with testimonials, word of mouth and referrals are a verbal form of social proof, and can have a huge impact on sales.

While personal recommendation is the gold standard, you donโ€™t need to wait for your clients to talk about you in order to harness the potential of word of mouth.

If youโ€™ve ever bought a product from Amazon, youโ€™ll be familiar with the line, โ€˜Customers who bought this item also bought …’ Not only are Amazon reassuring you that other smart people have purchased the product youโ€™re about to buy, but theyโ€™re using social proof to persuade you to buy additional products at the same time.

Creating an โ€˜Our clientsโ€™ page on your website that lists a range of people and businesses youโ€™ve worked with is another excellent form of social proof. It shows that other people have trusted you enough to hand over their money – and the world didnโ€™t end as a result of this transaction! Indeed, quite the opposite.

3. Spread your reach with social media

Having a certain number of connections, followers and fans on social media is another way of harnessing the power of social proof. People see other folks connecting with you, and they want to be part of the action.

4. User generated content (UGC)

One of the most powerful forms of social proof today is user-generated content. UGC refers to content created by people who are not an official representative of your business.

It may be:

  • a social media update naming, linking or tagging your business
  • an unprompted review on your social media pages or their own
  • a video of your products, such as an unboxing video
  • a brand mention in a podcast or blog

If your brand is involved but no employees or affiliates created it, itโ€™s user-generated content.

UGC brings authenticity and trust to your brand, as they are perceived as more ‘real’ than a review or testimonial that was prompted by the business.

Tips to highlight your social proof

Other people talking freely (and positively!) about your business brings powerful credibility to your brand. So, be sure to harness every bit of that goodwill by sharing the love.

Some tips include:

  • Reposting reviews, testimonials and UGC on your own social pages and website
  • Sharing your social proof wins in your newsletters to customers and clients
  • Commenting on others’ social media posts that mention your brand – a simple thank you from a business goes a long way, and also helps to bring new followers to your social media pages

Even if you didnโ€™t know what the term โ€˜social proofโ€™ meant before reading this article, I bet youโ€™ve already harnessed its power to generate leads and increase sales.

So, are you using your brand’s social proof effectively?
