About tRI
- The tRI is designed to compare all types of accommodation on one level in a clear and fair manner, by converting all covered sources to trivago's 10-point index.
- The tRI is not merely an average of numerical reviews. It is an index based on a mathematical algorithm that considers the individual ratings, the number of reviews that the rating is based on, and the recency of the reviews.
- The algorithm takes into account situations in which a hotel has only one rating source, in comparison to another hotel with a broad range of rating sources, and adjusts the calculation accordingly.
- A hotel must have at least 5 reviews in total in order to be included in the tRI.
- The tRI calculation is updated daily for each hotel based on the latest available rating information, ensuring that you always see up-to-date evaluations.
- Ratings from our partners that feed into the tRI can be found on our partners' respective sites (e.g. Expedia, Vrbo, etc.). We also use ratings from other web sources.
- You can find more information on how trivago promotes the integrity of reviews and ratings in our trivago Reviews Policy here. Our policy reflects the fact that we obtain reviews and ratings from third party sites and are therefore unable to verify theses reviews directly with users.
