Variables & TripAdvisor Ranking
An analysis of the total number of reviews, 5-bubble reviews, percentage of 5-bubble reviews and average review score showed that the percentage of 5-star reviews had the greatest effect on TripAdvisor rankings for hotels in Europe. If the percentage of 5-bubble reviews is increased by 10 percent, the hotel’s ranking is improved by 11.3 points; whereas, if the average review score is increased by the same percentage, the hotel’s ranking is improved by 6.1%.
For Asia-Pacific, the results were slightly different. If 5-bubble reviews were increased 10 percentage points, the hotel’s ranking improved by 3.7%, while the same increase in average review score increased the hotel’s ranking by 4.3%.
Impact of Ranking, Review Score, & 5-bubble Reviews on Bookings & Rooms Sold
Ultimately, better rankings, better review scores, and more 5-bubble reviews equate to more bookings, though their importance varies based on the geographic market.
- If the hotel’s ranking on TripAdvisor is improved, the bookings will increase (similarly) in Europe and in Asia-Pacific.
- Both the average review score and percentage of 5-bubble reviews increase bookings in both Europe and Asia-Pacific. However, the average review score has a greater impact on bookings in Asia-Pacific, while the percentage of 5-bubble reviews has a greater impact on bookings in Europe.
- While the same overall results apply to Rooms Sold as to Bookings, one notable difference is that a higher average review score yielded only a marginal increase in rooms sold in Europe and a substantial increase in Asia-Pacific.
- For Europe, the percentage of 5-bubble reviews shows the greatest increase in rates, followed by a hotel’s average review score. An increase in the hotel’s ranking only marginally increases rates for hotels within this study.
- For Asia-Pacific, the percentage of 5-bubble reviews is the only criteria shown to increase rates. Better ranking and higher review scores actually decreased rates in Asia-Pacific hotels. A possible explanation is if a hotel charges higher room rates, travelers may have higher expectations and, if disappointed in their experience, give the property lower scores.
Booking Channels & Reputation
The study surveyed web and non-web channels to assess correlations between travel reviews and bookings via each channel. Ultimately, the study concludes that average review scores have more impact on bookings than rankings via the web channel.
- Higher TripAdvisor ranking yields more bookings on the web channel: If the ranking of a hotel on TripAdvisor is improved by 10%, the expected number of bookings on TripAdvisor increases by 4.6% in Europe and 5.7% in Asia-Pacific.
- Higher average review scores on TripAdvisor positively impact web bookings substantially in Europe and even more so in Asia-Pacific: If the average review score of a hotel on TripAdvisor is improved by 10%, the expected number of bookings on TripAdvisor increases by 9.0% in Europe and 15.0% in Asia-Pacific.
- In Europe, travel reviews appear to have a greater impact for the non-web channel.
- In Asia-Pacific, on the other hand, online reviews have the biggest impact on driving web bookings.
Longevity of Reviews
The effects of average review scores/ranking decrease over time. An increase in ranking will show an increase in the number of bookings initially of approximately 5.2% but four weeks out the impact decreases to 3.5%.
The main goal of the study was to examine possible correlations between online reviews on TripAdvisor and hotel bookings for AccorHotels. The Statistical Consulting Unit of LMU Munich of the LMU Munich completed the analyses using a variety of modeling approaches, though tool of linear regression was primary. The data from AccorHotels included 225 hotels from Europe and 182 hotels from Asia-Pacific, with daily data available from 10-1-2013 through 11-01-2014.
