all so true @Mark71 - one cancelled reservation does it. you can always look at the superhost requirements and how you are "measuring up" : dashboard>stats>standards. it tells you right away where the "problem" is. so mine looks like this right now:
Commitment rate: 1 cancellation and your commitment rate drops under the required 100% .
Response rate: for booking "Requests" it is measured by hitting that approve/decline button within 24 hours.
If it is an "Inquiry" only, you do need to answer within 24 hours but need not hit pre-approve or decline, though Airbnb leads you to believe you need to do that also by keeping it red or orange red in your inbox and calling it late response - and then miraculously, that finally just drops off and disappears. kinda deceiving, pressuring you into pre-approver or decline.
5 star trips: that's where the anxiety comes in about not "measuring up" and hating 4 star reviews.
Review rate : just watch that over 50% of your guests leac ve a review. I hate propmpting guests to do so, worse even is to impress on them that it better be a 45 star review, or else...
Overall, I see no tangible merits in getting the superhost badge - and I say that as one who has it. So you get that shiny lil badge tacked onto your profile picture, what else?
You might think it gets you better ranking in the listing - not so, didn't make a bit of difference for me.
You might think guests will be impressed and thus book with you : I highly doubt that, as most guests don't even know what it means. You will get an Airbnb voucher or so after 1 year of superhost status - but that's about it.
In fact, I am against superhost because it creates so much drama, so much unhappiness about that dreaded 4 star review coming in, it makes hosts uptight, resentful - and fearful.
And all that for possibly feeling like "Airbnb likes me - I am special, I am superhost!" - No, not worth it!
It's simply a tool for Airbnb to keep hosts in line and docile, to do "better" - just like lil kids rejoice when they get that gold star in Kindergarten.
