Here are my further discoveries, thoughts, and guesses about the Guest Favorite category upon more reading:
- Selection criteria generation:
The selection criteria for Guest Favorite was generated based on the ratings, reviews, and reliability data from over half a billion trips. The source material for this generation ended September 30th, 2023. This comment is apparently intended to indicate that selections are made based on a robust and extensive evaluation process, and that the data that informs this evaluation process is current.
- Purpose is to solve choice overwhelm:
Apparently, the purpose for this new category is to help guests choose among overwhelmingly large numbers of highly-rated options. Airbnb's release highlights the frequency of positive feedback on their platform, with over 100 five-star reviews submitted every minute globally. This deluge of 5-star reviews is said to indicate a need for differentiation, resulting in a curated collection of Guest Favorites to help guests choose among the numerous highly-rated options.
- Evaluation frequency:
The evaluation of a listing for Guest favorite status apparently occurs daily (?).
- Two million cap:
Guest Favorite is a collection of the top 2 million homes on Airbnb. It appears to be capped at 2 million listings (?).
- AI Determined?:
My guess is that "guest favorite" status may be determined by AI. If so, there may not be an exact rule set to follow. The reason I think this is that there does not seem to be a clear limit to the recency of reviews taken into account neither in time nor in the number of reviews (last two years or last 5 reviews, for instance). Also, given that there is may be a cap of two million listings, and all listings are evaluated daily points to AI. This evaluation may take into account complex and subtle factors such as review language, review length, level of enthusiasm, and review frequency, and possibly things like occupancy rates. ?? If this is true, it may be impossible to create a straightforward rule set to follow. To me, AI determined selection seems likely. Either that or whatever they are using is simply getting it wrong. Who knows. I really wish they were more transparent about this category. Let's see.
