And @Katrina79 's No 1 in search results is a listing that has no average rating at all, it's a brandnew listing with zero reviews.
That's what the airbnb-algorythm does: It pushes new listings up in search results, then this listing gets many bookings and within 3 or 6 months the host of this place becomes superhost.
Now this host is totally excited over the badge and does everything in his or her power not to lose the superhost-status. This host will now please please please the guests and get on a „Yes Sir, Yes Ma'am“ one way street.
This, dear Ann, is the purpose of the superhost program, nothing else.
I'm preaching this now for more than a year, but noone understands me.
