NEEDHAM, Mass. - TripAdvisor is pulling back the curtain on its process for catching fake reviews.
The site's inaugural "TripAdvisor Review Transparency Report" provides insight into the moderation processes and key data. In 2018, TripAdvisor said users posted 66 million reviews, and its fraud-detection technology rejected 2.1% of those, or about 1.4 million reviews - with about three-quarters of those blocked before they posted.
The company said fraudulent reviews are generally one of three types: biased positive reviews, biased negative reviews or paid reviews.
TripAdvisor's content moderation team rejected or removed an additional 1.7 million reviews for guideline violations such as an incorrect location.
In total, TripAdvisor's combination of technology and human assessment rejected 4.7% of reviews in 2018 (3.1 million) either before or after they were posted.
In the report's foreword, TripAdvisor president and CEO Stephen Kaufer wrote, "No one has a greater incentive than TripAdvisor to ensure the reliability of the content on our platform. It is the core of our business because if people don't ﬁnd our content reliable and helpful, they won't keep coming back to our site."
Mr Kaufer went on to say third-party criticism is often based on "inaccurate figures”, so the report is intended "to provide deﬁnitive insights into the details and data behind our extensive content moderation efforts”.
“We do this in the spirit of transparency. We know we're not perfect. But we're constantly working to stay one step ahead of the people who try to abuse our platform - and we believe that no other review platform does more to protect the integrity of their content than TripAdvisor."
TripAdvisor said its users or businesses flagged less than 1% of reviews for possibly violating the platform's guidelines, and its content moderation team reviewed most of those within six hours of receiving that alert.
The company also enacted a "ranking penalty" on more than 34,000 businesses caught attempting to post fake reviews and, since 2015, it has stopped the activity of more than 75 websites it says were attempting to "sell" reviews.
"We've continued to make advancements to our industry-leading fraud detection efforts in recent years, but it's a daily battle and we are far from complacent," says Becky Foley, senior director of trust and safety at TripAdvisor.
"While we are winning the fight against fake reviews on TripAdvisor, we can only protect our corner of the internet. As long as other review platforms aren't taking aggressive action, then fraudsters will continue to exploit and extort small businesses for cash.
“It is time other platforms like Google and Facebook stepped up to the plate to join us in tackling this problem head on."
In the report, TripAdvisor also outlined steps it is taking to protect the integrity of reviews, including investing in training for human moderation teams, improving its fraud-detection technology, partnering with law enforcement authorities to tackle fake reviews and enhancing the transparency of its review moderation process.
