I am on Airbnb (only good for high season) and have been with Booking.Com for 6 months. I was getting up to 3 - 4 bookings a day but that is now majorly faltering due to me get quite a number of direct bookings. I think Booking.com work on the number of bookings you get, which improves your visibility. Would you stop accepting direct bookings? I have just added a beautiful new room but are currently not receiving any bookings. I don't want to bite the hand that feeds me!
Any suggestions would be warmly welcomed.
