@Sandy1018 from what I have seen success breeds success. So you need strong bookings to get to the top of the search listings. Of course you can't get bookings if not near the top so its a catch 22.
My advice is to edit the description, swap the photos around and comply with as many of the desired settings as you can swallow. So switch on instant book and move to a flexible cancellation policy. I think this will help you rise up the search placement.
