Due to the speed at which travelers are sharing their experiences on TripAdvisor, the company found instances where a newly listed property was able to skyrocket to the top of the rankings on relatively few 5-bubble reviews. TripAdvisor called these properties “fast-risers.” Over time, TripAdvisor travelers would submit more reviews on the fast-risers, causing them to settle into more stable, accurate rankings. Unfortunately, while this transition was happening, TripAdvisor consumers may not have been seeing the most accurate rankings for the destination. Fast-risers would temporarily enjoy higher positions before falling significantly in the rankings, and other businesses would appear lower than they would have otherwise. To improve our site experience for travelers and businesses alike, we’ve enhanced our Popularity Ranking algorithm. The enhanced ranking results in a more accurate representation of a business’s performance over time. These changes were not undertaken lightly and were carefully designed and tested to improve our rankings algorithm in some very specific ways, while maintaining the accurate standings of existing properties with great reputations among TripAdvisor members. In designing the enhancements, we analyzed the hundreds of millions of reviews we've received over the past 15 years and how they impacted the rankings of properties over time. Based on this research, we designed the enhanced Popularity Ranking algorithm to value the quantity and consistency of reviews more significantly than we have in the past. Doing so helps stabilize the ranking for all businesses, reduces fast-riser behavior and creates a more accurate overall ranking for our travelers. We’ve tested the enhanced algorithm extensively - both internally and by analyzing how travelers interacted with the site as we’ve gradually rolled it out. Get the full story at TripAdvisor
