There might be an advantage for Flexible.
Naturally, and there is a compound effect on response time for each new reservation (the reservation being automatically accepted by the host, the response time is 0; each new reservation will decrease the response time).
No. It will have an effect on your capacity to be listed however if you receive a lot of guests complaints, but that doesn't affect ranking.
Picture legends have an effect on conversion rate, but not on ranking.
Responding to review is not even accounted for. No.
The number of pictures is important. If there is less than 5 pictures, you will not be shown in search results on mobile.
Still under investigation.
Yes. And getting 5* reviews!
No. This number is actually a function of your ranking in the first place, and that would make the algorithm more rigid and prevent the visibility of newer listings.
Probably not, but it reassures people, so they book, and that is going to affect your ranking for sure.
Sure. The boost stops after you reach a certain threshold in number of days, or until you secure a few reservations to get things started and populate the first performance metrics for your listing.
Hardly. If you decline them quick, it won't have an effect. If you take your time, that will affect your response time.
No, but it does reassure guests, so should get you more bookings, and that will affect your ranking.
More view, more bookings, more momentum, so definitely yes.
Airbnb is built on momentum. The more views, inquiries, bookings, 5* reviews you get, the more you are likely to secure reservations. Airbnb likes winners, and will give you more leads.
The biggest variable on which hosts have power is response time, which is why it is important to respond quickly, (and why, incidentially, I believe humans don't stand a chance against a machine).
