@Celia6 Are you doing a general search with no filters of all the listings in your area? That's not the way to do it. Search like a guest would using filters such as price, number of guests, amenitites, etc. Then see where your listing stands. To learn more about search placement read this article:

Also, be aware of the fact that Airbnb puts new listings at the front of the search results so that they can get a few bookings under their belt. Once a listing has been around for a while it drops down in a general search. I've seen Super Hosts way in the back of the line.
