I have about 20 GMB on my main Gmail that I've set up over the past 5 or so years for some of my clients. All of these are legitimate businesses - no lead gen or anything like that. I'm wondering if there is a limit to how many GMB listings should be connected with a single email account. Do you guys have multiple GMB listings on a single Gmail ? Or do you have just a single gmail account for each GMB ?
