It obviously needs to be pointed out that Trustpilot operates an online review platform so has something of a vested interested. 

The survey also suggests that 60% of Brits have written a review in the past year, which I’m slightly dubious about though the figure could well be that high if you include comments posted on social media.

To further highlight the importance of consumer reviews, here’s a roundup of data taken from several other studies which show the impact they have on driving conversions.

And for more information on this topic, check out our blog posts looking at 10 ways to encourage customer reviews online and investigating whether the number of consumer reviews in PPC ads will affect credibility.

88% of consumers consult reviews

A study from Reevoo back in 2012 painted an even more extreme picture of the vital need for consumer reviews.

It suggested that a massive 88% of consumers ‘sometimes or always’ consult a review when making a purchase, and 60% were more likely to purchase from a site that has customer reviews on.

More than half of respondents (52%) said friends’ recommendations were influential, followed by consumer reviews (48%), advertising (24%) and advice from sales assistants (22%).

The findings in Reevoo’s report came from a nationally representative survey of 1,000 UK consumers.


After noting the efficacy of consumer reviews online, car brand Kia decided to display them in its dealerships as well.

Its customers could therefore see reviews of Kia vehicles and the customer service of the showrooms themselves in both an offline and online setting.

In addition, Kia used online reviews in its recent TV ad campaign, prompting viewers to head online to check out the opinions of people who have bought its cars.  

The results speak for themselves, as users reading reviews online were:

  • 484% more likely to request a brochure.
  • 300% more likely to book a test drive.
  • 509% more likely to search for a local Kia dealer.

Consumers trust recommendations from friends and family above advertising

Our post looking at how trust signals can double your conversions includes stats from a Nielsen study showing that 92% of consumers say they trust recommendations from friends and family above all other forms of advertising.

And according to a study conducted by Search Engine Land, 72% of consumers trust online reviews as much as personal recommendations.

Another study by nToklo suggests that UK retailers that don’t offer a platform for customer recommendations could be missing out by as much as £9bn in extra revenue.
