TrustYou, the world’s largest guest feedback platform, identified the biggest drivers of positive and negative online reviews through a detailed “Impact Score” analysis of the 90 million reviews that were analyzed in 2016. When more than 95% of customers make their booking decisions based on online feedback, the ability to improve and spotlight hotels reviews is critical. Impact Scores are determined based on an algorithm that lets a hotel know which praises or complaints in a review have the greatest impact on their overall review scores, based on analysis of more than 140 categories that guests use to describe their experience.
