Google is testing a feature in the local listings, the local pack, that shows how closely the listings match you. It is a feature Google announced but did not launch back in May 2018 called “your match.” Through machine learning Google shows “a number that suggests how likely you are to enjoy a place and reasons explaining why.”

Sergey Alakov spotted it in the wild and posted on Twitter this screen shot:

You can see match scores of 99% and 94%.

Here is a GIF of how it works based on what Google shared last year:

Again, I cannot replicate it and it disappeared for Sergey after a short while.
