The implications for businesses
Our advice is to continue to invite reviews to both your website, where we will publish them, and to Google. In fact, we are advising clients to ramp up their review gathering efforts wherever possible - see this article; Google will accept the review but not publish it for the time being. We will alert you as and when Google does publish reviews so you can then respond. Any reviews your business currently has will remain.
Don't do nothing: this will leave the field clear for any disgruntled customers who happen to use their current oversupply of free time to write their review which may then dominate the impression given on your Google listing when reviews are reinstated.
