Should we trust consumer reviews?
Yesterday, I read at Gizmodo that Reevoo (a leading provider of online review services to retailers) is warning shoppers to be careful when relying on reviews they read on the Internet. This might seem like an odd thing for a provider of reviews to be doing, but Reevoo’s business model involves pooling reviews across all its customers, and building its own brand as a trusted supplier of independent information, perhaps a bit like Which? Magazine. So Reevoo’s message can be translated as “our reviews are independent and reliable, beware other peoples’”.
I wrote last week about the benefits of consumer reviews on e-commerce websites: they help with search engine optimisation, and there is evidence they improve average basket value, conversion rates and return rates for many retailers. There is a real concern about the extent to which some retailers might edit unfavourable reviews, while others at the low end might just make up good ones. If 6 out of 10 consumers are strongly influenced by consumer reviews, there’s obviously an incentive for some to improve, or even manufacture, better feedback than they would otherwise receive.
This issue is on a continuum of questions regarding online trust. At one end we see trusted, peer reviewed academic writing, at the other unauthenticated random messages on Twitter, Facebook and Bebo, which might be inaccurate, slanderous or even criminal in some cases - the name of someone who might have been involved in a murder briefly appeared in comments on a Youtube video last week, according to this article.
Clearly you shouldn’t believe everything you read, and this is why trust models like ebay’s have become so successful. Tim Berners-Lee addressed the question at his lecture at the BCS in March. There might be better technical solutions on trust soon, but for now it’s not surprising that people are questioning consumer reviews. If Wikipedia can be amended by the CIA, to suit their world view, we should be careful before trusting anything we read.
One of the powers of a brand is to create that kind of trust for the information it provides. Would John Lewis fix its reviews? The reason most people would say not is that their brand is so strong. And that’s based on decades of hard work.
