There is something else going on. Search on this community for 'summer release' and 'categories' and you will soon see what I am talking about.
In early May, Airbnb totally changed its search functionality with the result of a lot of listings suddenly dropping in search results or dropping off the map. My listings, which were always fully booked since I started doing this in 2016 suddenly dropped down the results, disappeared from the map (unless you clicked directly over my house) and views and bookings stopped in their tracks.
Things have improved for me more recently, although it's certainly not back to how things were prior to the Summer Release. This may be because there were a lot of glitches in the new system, and perhaps some of them have been fixed, but the problem remains that the overall system and its algorithms are doing no favours to many previously successful hosts.
RE @Sudsrung0 's suggestions, there is always room for improvement, but if you are not showing up at all, it won't make a huge difference. Except, we were informed after the Summer Release that the algorithm picks up on certain key words in listing descriptions and reviews, as well as prioritising listings with better photos. I am not totally convinced about that to be honest, as my photos were taken by professional Airbnb photographers and there are listings with rubbish photos showing much higher than mine... But still, it's worth a shot.
