Airbnb puts new hosts at the top of the list so they can get some business right away. After that, where you show up on the list will depend on reviews, number of guests hosted, super host status, etc. I've seen very experienced host's listings with good reviews far back in the listing order. If you want to direct people directly to your listing, give them the link. (airbnb.com/rooms/XXXXXXX). I make business cards with the link to my space so people don't have to wade through everyone else's listings to find me. Hope this helps!
