Managing Google Reviews[ Edited ]
March - last edited March
I'm not sure how Google determines which reviews display here (though, no doubt it is based on some algorithm).
As far as I'm aware, there currently isn't any way to specify which listings show first.
Assuming your goal here is to 'push down' the negative listing/s, the only way I'm aware of is to aim for more positive reviews which should organically push down the bad ones.
If you have a genuine concern that the negative review is inappropriate, there is some advice here on how to flag and fix inappropriate reviews.
