The profile page only shows 2 listings, then a small textlink beneath them says 'show all", which is easily overlooked.
The homepage shows more listings, up to 12 per page, in a nicer layout.
Airbnb calls it "your marketing page" on the Dashboard.
It is the one te be used for external linking (and not the profile page)
It is odd "your (own) marketing page" can not be included as a clickable link in a listing.
It should be added to each listing by default, especially when there is more then 1 listing.
