- You can use the "share" button on top of each listing to promote on social media or another website.
- You can turn on/off a setting in your account to grant other search engines access to your listings.
- Your homepage can be linked to other websites, blogs etc.. (but first upload a cover photo !)
- Your listings have a feature to create a custom URL
There is an (very) old post here about the subject:
Direct marketing for your Airbnb
My personal experience is posting in relevant facebookgroups generates significant traffic to my listing(s). I also use a private website with links to listings / homepage.
