Ensuring your listing is completely up to date with your calendar, photos and rates will improve your search results. Being a responsive owner to inquiries and booking requests will also help give your listing a boost. Letting a booking request expire or having many declined bookings will negatively impact your overall ranking in the search results.
You also may want to consider enabling Instant Book on your listings. Instant Bookable properties (or IB properties) are prioritized in our search results. As a property owner, your Instant Bookable status is just one of many things that will affect your placement in the search results.
