@Sybe Unfortunately, the "machine learning" isn't learnin' good. LOL It definitely needs some tweaking. It is leading guests astray which will result in a negative guest experience.
Your advice is "making sure all your listing details are up-to-date and having pictures of high quality that show the key features you want to highlight does increase your chances of being included in a certain category" which sounds great. However, that's exactly what I've done and still not categorized properly.
One of the places I manage has an amazing view! It has superhost status and hundreds of reviews. The amazing views are in the TITLE, it is in the DESCRIPTION, it is in all the reviews from the past 100 guests mentioning the exact same words "AMAZING VIEWS" and most importantly the photos (including the first photo) is a photo of the AMAZING VIEW and the photo was and Airbnb photo uploaded by Airbnb from the Airbnb-assigned photoshoot! It is clearly an AMAZING VIEW property but when you select the amazing view category for the 50 cabins in our lake community, only 4 cabins show up and 3 of them have no view at all. Clearly the AI is missing the I. A simple temporary solution would be to have a request form for hosts to fill out to request being added to a specific category. Then an actual human can verify that the AI is off and fix the problem.
Another place I manage is a plain square cabin with no vaulted ceiling. Yet when you select the "A-Frame" category it shows up even though it is NOT an A-Frame style cabin. I really hope this doesn't lead to buyer's remorse and negative reviews from guests who thought they were renting an A-Frame since that is what Airbnb categorized it as... 😞 Meanwhile, our two cabins that ARE A-Frame style are not listed at all under that category.
I hope Airbnb improves this feature soon.
