UP to a third of reviews on TripAdvisor are fake with hotels and restaurants buying positive reviews, it has been claimed.

Analysis of tens of thousands of reviews on the site has shown that top rated bed and breakfasts have almost twice as many “false” reviews as lower ranked establishments.

4 Websites are offering owners the opportunity to purchase positive reviews for a fee

An investigation has found that websites are offering glowing reviews for £38, according to The Times.

Others allowed owners to bulk buy reviews for less money, with one offering 10 positive reviews for £69.

One restaurant owner admitted to the paper he had already posted “a large number of positive reviews” but wanted further help to boost his ranking.

He wrote to a website offering fake reviews set up by The Times: “I’m looking to improve my TripAdvisor account, I’m currently 3.5 [out of five] and would like to be 4.5 in the next month, please let me know if you can help.”

4 Up to a third of reviews on TripAdvisor are fake according to an investigation

Analysis of the reviews was done by Fakespot.com which uses an algorithm and machine to identify suspicious reviews.

Fakespot’s analysis does not prove that a review is fake or that a venue has necessarily benefited from them.

Many of the venues listed in TripAdvisor’s top ten rankings appear to have genuine reviews.

Saoud Khalifah, Fakespot’s founder, told The Times: “TripAdvisor has a huge set of problems.

“From our database, the mean of fake reviews is 32.9 per cent. For B&Bs, that rises to 41.9 per cent.

4 The site doesn't just offer its services for TripAdvisor but for a host of other sites

There are a large number of accounts with one or two reviews created by people within hotels or restaurants that have posted fake reviews.

“I would advise TripAdvisor users to approach every review with scepticism.”

Consumer groups say that fake reviews are a growing problem, fooling buying substandard goods and services.

It is estimated that more than £14 billion a year is spent on travel and hotels as a result of reviews.

TripAvisor gets more than 50 million visits a month from users in Britain alone.

The site has flatly denied the allegations saying: “We totally reject the inaccurate and misleading findings presented by The Times. Their claims about fake reviews on TripAdvisor are astonishingly bad ‘click bait’ journalism.

“The usefulness and accuracy of the content on TripAdvisor is what has made our site popular to hundreds of millions of consumers.

“We’ve never lost sight of that and it’s why we fight fraud so aggressively. Learn more about how we do that here.

“The Times investigation is based on entirely flawed techniques.

“The methods used by Fakespot are completely unreliable for one simple reason: they have no access to the technical data you would need to determine whether or not a review is fake.

“We do, and we have been using this data for over a decade to track millions of reviews.

“If Fakespot’s methods were in any way reliable, we would be using them.

"We have tested their analysis, with reviews we know to be either genuine or fake, and the results show it to be completely unreliable and inaccurate.

“We are the experts in catching fake reviews, not Fakespot. Their business model is dependent on convincing users that review sites cannot be trusted. Our site is built on trust.

"If the content wasn’t useful, if it wasn’t delivering great recommendations, then consumers wouldn’t keep coming back to the site.”

Responding to TripAdvisor's comment, a Fakespot spokesman said: "Fakespot's mission is to bring trust and transparency back to the Internet and improve the consumer experience on sites where we analyse reviews, including TripAdvisor.

"If our service saves only one consumer from booking a holiday based on fake reviews then we have done our job.

"Contrary to TripAdvisors claims, we have access to all of the technical data we need to give consumers a reliable Fakespot Grade of reviews on TripAdvisor.

"Furthermore, to express that we are not experts in catching fake reviews is not supported by the fact that we are trusted by millions of users to spot fake reviews on Amazon, Yelp, TripAdvisor and the Apple App Store.

"On Amazon alone, we have analysed over 2 billion reviews and have saved countless consumers from buying products based on fake reviews."
