What is testimonial advertising?

Testimonial advertising is a tactic that promotes customer reviews and experiences across various marketing channels. It leverages the authenticity of these testimonials to showcase the value of your brand, product, or service, and it’s an effective way to establish trust and persuade potential customers.

This is the exact quality of testimonials that you can leverage through testimonial advertising. You can promote your customers’ testimonials to your audience through your ad copy and creatives to win them over. 

Owing to the highly impactful nature of testimonials, they can be a great asset for driving your lead generation and sales efforts.

Pro tip: Testimonials and endorsements differ significantly.

Testimonial advertising typically relies on input from everyday customers. While some customers might leave feedback without expecting incentives, others may do so in exchange for a gift card or discount.


In contrast to testimonial ads, endorsements typically involve celebrities who are paid generously to promote a brand’s products or services.


As for influencers, if they have a small following, their reviews can be seen as testimonials. But for mega-influencers, it’s often considered an endorsement due to their significant reach and compensation.

Importance of testimonial advertising

Testimonial advertising is a powerful tool for building trust and credibility with your audience, because it allows you to highlight real customer experiences. 

Testimonial advertising also helps overcome skepticism and alleviate concerns that potential customers may have. When someone can relate to the experiences of others, they’re more likely to trust that your product will deliver the same value.

By strategically leveraging customer testimonials in your marketing efforts, you can boost engagement, build credibility, and, ultimately, increase sales.

Types of testimonial advertising

As previously stated, there are four major types of testimonials: 

  • Text: These are written recommendations from customers and could include things like Yelp reviews, customer quotes, or product page reviews
  • Images: Image testimonials effectively convey customers’ satisfaction by sharing pictures and visuals showcasing their positive experiences
  • Videos: Video testimonials feature happy customers’ voices and are perfect for sharing on your website, YouTube, or social media
  • User-generated content: User-generated content testimonials are when customers share their experiences with your brand, like posting photos on social media

You may utilize each to your advantage, depending on the availability of reviews and customer approvals, to use them for testimonial advertising.
