You can use the "share" option on your listing to promote it on Social Media.
The URL to the homepage can also be used to promote listing(s) on an external website.
BTW Your homepage needs a coverphoto:
https://www.airbnb.com/users/195617756/listings
i also own a private website, with links to my listings and Airbnb homepage.
I learned promoting on facebook groups generates bookings !
