@Ros52 Good, very comprehensive list, except for few things.
"and remember, Airbnb takes care if its hosts, they will take your side if you are honest, polite and mean business."
This may luckily be your own personal experience, but it isn't the experience of a great many hosts, and new hosts shouldn't fall for this false assurance. Airbnb is extremely guest-centric and generally takes the guests' word over that of hosts more often than not.
Thumbs up, or participation on this forum have zero to do with a listing's search ranking.
Superhost has little if anything to do with search ranking.
1 night bookings are often the most problematic and can be made with the intention of throwing a party. Many hosts have upped their minimum night stay because of this. Of course there are listings in locations where 1 nighters are their bread and butter, like if they are close to an airport and get a lot of guests looking for accomodation for a layover or early morning flight
I don't agree with the concept that low prices bring low quality guests. I have a budget priced listing for what I offer and my area and all my guests have been lovely people. They don't steal towels or anything else. They leave their space clean and tidy, bring me "hostess gifts", and have been super respectful and appreciative.
Many travelers have simple needs and choose to spend their money on things other than expensive accommodation.
