@Anne12492 When you look at your listing details, what does the categories entry list as the category entry your property has been assigned? If the word Cabins is not there, then searching for cabins will not include it in the search. You have done a good job of adding the word Cabin to your listing title and text...wait it out a little, the AI may eventually add Cabin to your category assignment.
You could try contacting AirBnB. However, I found that CS did not have way of assigning a category to a property. It was all done by the AI. I wasn't listed under cabins for about 6 months as my attention-grabbing thumbnail is a picture of the waterfall that is on my property.
