Google is harder because when their alog updates happen. They dont just go after the reviews. They also go after emails. One has little to no control over when they hit from all sides.
I tell this from watching algo updates over 4 years.
Yes if you spend a lot more to keep the email alive, and generate activities manually, the chances are less. But this is'nt viable, its like using a hydraulic hammer to hit a bunch of flies.
My approach to this is, post, let it rank, and then move on to the next listing when it gets hit. For GMB if someone is into lead generation/PPC
