I'm really not sure how true that is.
I wish I could find it now but can't as it's a bit old, but there was a thread on here where some hosts from different locations decided to do an experiment. They searched on Airbnb using the exact same criteria (location, property type, number of guests, dates) and compared the results.
One of the things that came up in all of their results was that star ratings do not mean a **bleep** thing in terms of placement. Many of the top results had ratings below the 4.7* that is supposed to be a minimum requirement. In fact, quite a few of them had 3.something stars, including the in the very top results. Hardly any of the first page results were Superhosts.
Okay, so if you are a Superhost your listing will show with that label (unless it's a 'rare find', in which case you will see that badge instead), but that doesn't mean Superhosts or listings with high ratings appear higher in the results. The only real advantage that I can see is if guests choose to apply the Superhost only filter when searching, but honestly, how many are going to do that, especially as they have to first click on the filter menu and then the Superhost filter option is right down near the bottom of the list?
