A lack of bookings can be due to many different reasons.
Increased competition, competition lowering their prices, people being cautious about discretionary spending due to economic climate, and if you are located in the US and get international guests, the tourism numbers have plummeted due to the present administration’s policies.
Superhost has little to do with bookings. Hosts who have had it, lost it, and regained it, etc., as I have, have found it made no difference to their booking rates. And Airbnb eliminated the Superhost filter about a year or more ago.
My listing is a homeshare in Mexico and 2025 has been my best booked year so far, since I started hosting in 2016, so lack of bookings is not universal.
