This London Research study reports on the benefits of using Trustpilot ratings and reviews in advertising to build trust and increase propensity to purchase.
The research also looks at the extent to which specific types of Trustpilot content in online advertisements influence US consumers, including the Trustpilot logo and stars, TrustScore, the volume of reviews, and the impact of an authentic customer testimonial.
To test the value of Trustpilot ratings and reviews in ads, 1,000 American consumers were shown a series of digital advertisements for a new cell phone plan, and asked which ads they would be most and least likely to click in order to buy.
Summary of the research
- 63% of US consumers agree a good Trustpilot score makes them more likely to trust a brand.
- 61% agree a good Trustpilot score makes them more likely to buy from a brand.
- An online advertisement with the Trustpilot logo and stars is 37% more persuasive than the same ad without them.
- Consumers are two-and-a-half times more likely to click a Trustpilot co-branded ad showing a five-star customer rating, TrustScore, 3,000+ reviews, and a customer review, than an ad with no Trustpilot content.
- A Trustpilot five-star advert with a 4.8 TrustScore showing 500+ reviews is more than twice as compelling as an ad with no Trustpilot branding.
- A Trustpilot five-star advert with a 4.8 TrustScore showing 3,000+ reviews is 31% more compelling than the same ad just showing the TrustScore.
- A Trustpilot five-star advert with 3,000+ reviews performs 10% better than the one with 500+ reviews.
- A five-star ad showing a high TrustScore with 3,000+ reviews and an actual customer review performs twice as well as an ad with no Trustpilot components, even when the price is 20% higher ($48 versus $40).
The importance of ratings and reviews in the buyer journey
Consumers are right to be cautious about putting their trust in brands when they’re looking to buy products and services online. According to the Federal Trade Commission, Americans have lost $588m to scams during the pandemic era alone, which makes people even more eager to ensure they’re buying from a reputable business and spending their money wisely. At the same time, consumers are becoming increasingly savvy about fake reviews used by less-known brands to bolster their credibility.
Our research shows that authentic customer reviews and star ratings are now firmly established as a go-to source of information for the majority of shoppers. Sixty-four percent of US consumers say they’re ‘often’ or ‘very often’ influenced by customer reviews during the journey to purchase, while 63% say the same for star ratings (Figure 1).
This does not surprise Kyle Rao, President and CEO of Secure Medical. As the company behind eDrugStore.com, they are fully aware that consumers need to see that people like them have used a service before, and rated it highly.
Ratings and reviews play an important role in influencing buying decisions across a wide range of categories, from electronics to travel, and property to auto rental. For every sector shown in Figure 2, at least half of consumers surveyed regard ratings and reviews as ‘useful’ or ‘very useful’.
Advertisers should strive to understand how different touchpoints and channels work together to build trust and positively impact the decision-making process during the customer journey.
After customer ratings and reviews, the next most frequently visited touchpoints in influencing a buying decision are search engines, followed by ecommerce sites and social media (Figure 1). Given their usefulness and popularity, savvy marketers should think about how they can harness ratings and reviews across other channels, including both online and offline advertising, as well as across their own digital properties and email campaigns.
SuretyBonds.com is a good example of a financial services brand showcasing star ratings and customer reviews.
The benefits of Trustpilot content through the funnel
The trust engendered by adding Trustpilot stars and scores to digital advertising is not just good for brand image, it is also a core component in driving sales. Sixty-one percent of US consumers agree a good Trustpilot score makes them more likely to buy from a brand, including 26% who strongly agree (Figure 3). The propensity to buy something from a company is very closely linked to the level of trust in that brand. A very similar percentage of consumers (63%) agree that a good Trustpilot score makes them more likely to trust a brand (Figure 4).
Brands are seeing this throughout the customer journey. For Octopus Energy Germany, a green energy supplier, adding its star rating is a way for it to build trust while also raising awareness at the top of the funnel.
At fashion brand Bamigo, work is under way to add the Trustpilot logo, star rating and customer reviews to all its product pages because, as the company’s Marketing Manager Freek Rijken reveals, they are proving highly effective at the purchasing end of the funnel as well as the awareness stage. He believes this is because they convey to prospects how happy existing customers are with the quality of its products and service.
The impact of Trustpilot
1. Logo with star rating
We have seen that consumers say they’re more likely to trust and buy from a brand with a high Trustpilot rating. A key objective of our research was to understand the impact of different Trustpilot content elements, namely the logo and stars, TrustScore (out of five), number of reviews, and an actual quote from a customer.
As part of our proprietary research, consumers were shown a series of digital advertisements for a new cell phone plan, and asked which ads they would be most and least likely to click in order to buy.
The research found that an online advertisement with the Trustpilot logo and stars is 37% more persuasive than the same ad without them.
Another finding from the research was that consumers looking to buy something are two-and-a- half times more likely to click a Trustpilot co-branded ad with a five-star customer rating, high TrustScore, 3,000+ reviews, and a customer testimonial (compared with a baseline ad with no Trustpilot vs. branding).
As well as seeking to understand the overall impact of the full suite of Trustpilot content and the logo and stars on their own, we also wanted to explore the relative impact of different content components, namely the customer review, the TrustScore at different levels, and the volume of reviews.
2. Customer review
US consumers are 88% more likely to click through on a Trustpilot co-branded ad when it contains an authentic customer review.
Micael Saillen, CEO and Co-Founder at energy supplier Tate, has quantified adding a customer review as typically improving digital advertising clickthrough rates by 10% to 20%.
“People know brands say they are great in their adverts but when a company shows what people actually say about them, consumers know the advertiser is showing they have nothing to hide,” he says.
US consumers are 30% more likely to click through on a like-for-like Trustpilot co-branded ad when it specifies the high TrustScore behind the five-star rating. The ad with a 4.8 score performs 75% better than the ad with a 4.2 score.
4. Number of reviews
A Trustpilot five-star advert with a 4.8 score showing 500+ reviews is more than twice as compelling as an ad with no Trustpilot branding, according to our research.
Mike Henderson is Chief Marketing Officer at SuretyBonds.com, which has a 4.9 TrustScore. He credits adding the number of Trustpilot reviews on the company’s digital advertising with delivering a 20% improvement in clickthrough rates.
Our consumer research also shows that a Trustpilot five-star advert with 3,000+ reviews performs 10% better than the one with 500+ reviews.
According to Dan Cristo, Director of SEO Innovation at performance marketing agency Catalyst: “One of vs. our clients in the hospitality space has an average of 2,000 reviews on each property. These are real experiences customers volunteered to share with others simply because they wanted to tell their story. This desire to share experiences with others as a way to ‘pay it forward’ and help others in the community is a core part of how humans socialize.”
5. Impact on higher price
The research also found that a Trustpilot ad with five stars, TrustScore, 3,000+ reviews and a customer testimonial performs twice as well as the ad with no Trustpilot content, even when the price is 20% higher.
Adding all the possible elements of a Trustpilot rating — including logo, stars, score, number of reviews and a customer quote — is certainly paying dividends at fintech business PensionBee. Its Chief Marketing Officer, Jasper Martens, reveals the company puts all elements on its digital advertising which it credits with delivering a 15% rise in clickthrough rate.
“For us the Trustpilot logo and our score are a nudge to check us out,” he says. “The number of reviews is crucial in convincing people you’re providing a good service because if you have more than 5,000 people know it’s real, it’s very powerful. Ultimately, the customer voice is the main convincer, we believe, so customer reviews are essential.”

About London Research
London Research, set up by former Econsultancy research director Linus Gregoriadis, is focused on producing research-based content for B2B audiences. We are based in London, but our approach and outlook are very much international. We work predominantly, but not exclusively, with marketing technology (martech) vendors and agencies seeking to tell a compelling story based on robust research and insightful data points.
As part of Communitize Ltd, we work closely with our sister companies Digital Doughnut (a global community of more than 1.5 million marketers) and Demand Exchange (a lead generation platform), both to syndicate our research and generate high-quality leads.
London Research was commissioned by Trustpilot to carry out a survey of 1,000 US consumers in September 2021. The nationally- representative survey included questions about sources of information and touchpoints used during the buying process, and also questions specifically about Trustpilot. A third (33%) of respondents said they were aware of Trustpilot customer ratings and reviews.
A survey-based research technique called MaxDiff was used to quantify consumer preferences when respondents were shown different combinations from a series of 10 different advertisements. Survey respondents were asked which online ads for a new cell phone plan they would be most and least likely to click in order to buy. The Appendix shows the 10 different ads shown to consumers, and the full results for the MaxDiff analysis (with relative levels of engagement expressed as percentages). The same research was carried out in the US, UK, Netherlands, Germany and Italy (5,000 consumers in total).
