Google Maps App Highlighting Businesses that Have Posted Recently
Google is wanting to draw attention to the Updates tab for businesses that have recently posted an update to their knowledge panel. The Google Maps app is prone to highlighting businesses that have remained active or recently made a post. Expressed with a little red dot near the updates tab, it's clear that active posting is rewarded by Google Maps for this action.
