Sales is trust, especially online.

No one knows who you are or if what you’re trying to sell works, and you want me to give you my money? I don’t think so! 

This is how many people think when reading through your sales message.

So how do you fix this? Social proof.

Social proof is the only way to tell strangers, “Hey listen, others have tried my stuff and they loved it. Here are the nice things they’re saying about it.

Doing this as a digital marketer is one of the major ways to get strangers to whip out their wallets and give you their hard-earned money.

In this post, you’re going to discover what social proof is, why it’s important, and how to use it in your sales messages.

Finally, you know I can’t talk about anything without showing you how to use it in your sales letters to generate more sales in literally hours.

Let’s begin:

What is Social Proof?

Social proof is a psychological phenomenon where people assume the actions of others in an attempt to reflect correct behavior in a given situation.

It’s the idea that if others are doing something, it must be the right thing to do.

In marketing, social proof can be used to build trust and influence potential customers.

Types of Social Proof

  1. Customer Reviews and Ratings: Positive reviews and high ratings can be one of the most effective forms of social proof. They serve as endorsements from real customers, helping to build trust and credibility.

  2. Case Studies: Sharing success stories of customers who have gotten results using your product or service can be very persuasive.

  3. Testimonials: Written or video testimonials from satisfied customers are powerful tools to gain the trust of potential buyers.

  4. Social Media Shares and Likes: High social media engagement can show that your brand is popular and trustworthy.

  5. Endorsements by Influencers: When influencers or industry experts endorse your product or service, it can really boost your credibility and increase sales.

  6. Press Mentions: Being featured in reputable media outlets or publications can boost your brand’s reputation.

What are Testimonials?

Testimonials are statements from satisfied customers of your product or service.

They provide a personal touch to your marketing efforts, as they are often in the words of real people who have had a positive experience with your brand.

Testimonials exist in many forms, like written quotes, video clips, or even audio recordings.

How to Use Social Proof and Testimonials to Increase Sales

Now that you have a solid understanding of social proof and testimonials, let’s talk about how to use them to increase your online sales.

1. Let Your Testimonials be Easy to See

Amazon, the e-commerce giant, uses customer reviews and ratings like a Jedi.

Make sure these testimonials are visible on your website.

Use pictures of satisfied customers alongside their testimonials. That way, people will know that you’re not trying to decide them.

2. Use Video Testimonials

Slack uses video testimonials on their website.

These video testimonials allow potential customers to see and hear from real people who used and loved their service.

This adds an extra layer of authenticity to their marketing.

Try using video testimonials because they’re more convincing than written testimonials.

If you have the money, you can also hire a professional videographer to make sure production quality is high.

But there’s a caveat:

When your customers record themselves, sometimes their camera quality is low, this can be an added advantage.


Because you and I know that everyone does not have high-quality phones.

Therefore, we can trust video testimonials of people with bad video quality than if all the videos on their website look like a studio-quality movie. 

3. Use Before-and-After Stories

The weight loss industry uses powerful before-and-after stories to show the transformation their products or programs can get potential customers.

These stories are highly relatable and inspire trust.

Add customer journeys, showing where they were before using your product or service and where they are now.

This approach can be effective for products or services that bring about significant change or improvement in people’s lives.

4. Show Social Media Engagement

Coca-Cola uses social media engagement in its marketing materials.

They use hashtags and user-generated content to show the popularity of their brand and products. This social proof reinforces their global presence.

You can integrate social media feeds on your website to show user-generated content related to your brand.

Encourage customers to share their experiences on social media using your unique brand-specific hashtag.

5. Show Influencer Endorsements

Daniel Wellington, a watch brand, used influencer marketing to achieve rapid success.

They worked with influencers to create a buzz around their products.

This influencer endorsement strategy helped them gain massive visibility and credibility among their target audience.

Identify influencers in your industry who align with your brand and values. Collaborate with them to create content or endorsements that sell your product or service.

6. Create Case Studies

HubSpot is known for its extensive collection of case studies.

These stories show how their customers have gotten results using their platform.

Create case studies that show the challenges your customers faced, how they used your product or service to overcome these challenges, and the results they achieved.

Case studies can be highly persuasive, especially for B2B and high-ticket products or services.

7. Use Press Mentions

Apple often uses press mentions on their website and marketing materials.

Being featured in respected publications boosts their brand reputation and builds trust.

Compile a list of any press mentions, awards, or recognition your brand has received and display them on your website to show your credibility and authority.

How to Use Social Proof and Testimonials in Copywriting

Effective copywriting is the cornerstone of persuasive marketing. Here are strategies for adding social proof and testimonials into your copy to boost sales.

These places are headlines, subheadings, and the main body of your copy.

Use testimonials that are relevant to the product or service you are promoting.

2. Use Specific and Quantifiable Testimonials

Rather than vague statements like “Great product!” use testimonials that use specific details and numbers.

For instance, “After using XYZ product, I saw a 30% increase in website traffic within a month.”

3. Address Objections

In your copy, address the prospect’s objections or concerns.

Then, use testimonials that directly counter these objections.

For example, if cost is a concern, use a testimonial from a customer who talks about the exceptional value they received.

4. Test Different Testimonials

A/B testing can help you identify which testimonials work best with your audience.

Try out different testimonials in your copy to know which ones lead to higher conversion rates.

5. Create a Compelling Headline

Use a compelling testimonial as your sales letter headlines to immediately grab your reader’s attention.

For example, “Discover How [Customer Name] Increased Their Revenue by 50% with Our Product!”

6. Use Testimonials in Emails

When sending out marketing emails, add short but impactful testimonials to increase open and click-through rates.

Encourage recipients to click through to your landing page for more detailed testimonials.

7. Use Testimonials in Call-to-Action Buttons

Add testimonials to your call-to-action (CTA) buttons.

Instead of a generic “Buy Now,” use something like “Join [Number] Satisfied Customers and Buy Now!”

Best Practices for Adding Social Proof and Testimonials to Your Sales Letters

Whether you’re selling a product, a service, or an idea, using social proof and testimonials in your sales letters can increase the effectiveness of your sales letter.

They provide evidence of your product’s value.

Here are the best ways to add social proof and testimonials to your sales letters to increase your conversion rates.

1. Know Your Audience

Not to beat a dead horse, but…

Understanding your target audience is a major step in crafting a persuasive sales letter.

Before adding social proof and testimonials, you need to know what matters most to your potential customers.

What are their pain points, desires, and objections?

Using social proof and testimonials to address these specific aspects will make them more compelling.

For example, if your target audience is concerned about the effectiveness of a weight loss product, a testimonial that emphasizes significant weight loss results can address this concern effectively.

2. Choose the Right Testimonials

Not all testimonials are created equal.

The key is to select testimonials that work best with your audience. Here are some factors to consider when choosing testimonials:

Relevance: The testimonial should relate directly to the product or service you’re selling.

Specificity: Specific details and numbers, like a 30% increase in sales or a 20-pound weight loss, make testimonials more compelling.

Relatability: Customers are more likely to trust and relate to testimonials from people who share similar demographics or situations.

If possible, choose testimonials from customers who closely resemble your target audience.

Authenticity: Authenticity is key.

Avoid using overly polished testimonials. Real, honest, and genuine testimonials are more persuasive.

3. Show Benefits and Results

When using testimonials in your sales letter, make sure they focus on the benefits and results that your product or service offers.

Customers are interested in what they will gain from you.

Show how the product has improved the lives of other customers, whether through increased productivity, cost savings, better health, or improved quality of life.

For example, if you’re selling a time management app, a testimonial could show how it helped a customer reclaim hours in their day, resulting in reduced stress and increased productivity.

4. Use Pictures

Visual elements can add impact to your testimonials.

If you have access to photos of the people providing the testimonials, add them.

A smiling, happy face can reinforce the positive experience conveyed in the testimonial.

Also, you can use video testimonials for a more immersive experience.

Video testimonials capture the emotion and sincerity of the customers, making them highly persuasive.

5. Add Testimonials in Strategic Areas of Your Sales Letter

In your sales letter, strategically place testimonials in areas that matter most. These are places like:

Headlines: Start your sales letter with a compelling headline that features a testimonial. For instance, “Discover How [Customer Name] Boosted Their Business with Our Product!”

Subheadings: Testimonials can also be used as subheadings, breaking up your copy and drawing the reader’s attention.

Within the Body: Add testimonials within the main body of your sales letter to reinforce the points you’re making.

For instance, if you’re trying to highlight a product feature, place a relevant testimonial nearby to show its benefits.

Near the Call to Action (CTA): Just before or near your CTA, add a powerful testimonial that reinforces the decision to take action.

It can help remove any last-minute doubts.

6. Address Objections

Testimonials are an effective way to address objections your potential customers may have.

Common objections might be concerns about the price, skepticism about the effectiveness of the product, or uncertainty about the buying process.

For each objection, add a testimonial that directly counters it.

For example, if price is an objection, use a testimonial from a customer who initially had doubts about the cost but found the product to be a valuable investment.

7. Test Different Testimonials

A/B testing is a valuable technique to know which testimonials are the most effective.

Experiment with different testimonials and monitor the conversion rates.

This data-driven approach will help you identify which testimonials work best with your audience and can guide your selection process in the future.

8. Create a Sense of Urgency

Testimonials can also be used to create a sense of urgency in your sales letter.

For example, you can use a testimonial from a customer who hesitated initially but decided to take action and got remarkable results.

This can encourage readers to act fast to avoid missing out.

9. Keep Testimonials Fresh

Continuously update your testimonials to keep your sales letter current and relevant.

If your product or service undergoes improvements or you get new positive feedback, make sure to add this to your sales letter.

The Importance of Trust and Credibility

Social proof and testimonials can seriously improve your sales. They build trust which is important for increasing sales.

The world of marketing is constantly evolving, but one thing remains constant: the importance of trust and credibility.

Social proof and testimonials are the means by which you can establish and reinforce this trust with your target audience.

When potential customers see real people who have had positive experiences with your product or service, they are more likely to convert into paying customers.
