Google's Jade Wang has offered some important clarification on the scenario of set-and-forget Google My Business dashboards - Google could determine that they are inactive and un-verify the listings they contain. She writes,
"In some cases, we may contact Google My Business users via email to confirm that they are still actively managing a business page. If a user is unresponsive to our attempts to contact him or her and has not logged into Google My Business for a significant length of time, then we may unverify pages in the account. We're doing this in order to continue to provide users with the best experience when they’re looking for local businesses like yours. If you find that a page in your account has been incorrectly unverified, please contact support to get assistance restoring verification. It's a good idea to keep an eye on the inbox associated with your Google My Business (Locations) account. It's also a good idea to regularly log into Google My Business (Locations) to confirm that your business information is current and accurate."
Mike Blumenthal initially posted that it was necessary to perform a null edit (a tactic in which you view the edit screen of your Google+ Local listing and hit 'save' without making any changes), but Mike has since updated his post to clarify that a null edit isn't actually necessary. According to what Mike learned, you can simply log into the dashboard once every few months, or if you have to make real edits or you post on your page, that should provide an adequate signal to Google that the dashboard is still being actively managed.
In the past, an agency with a limited contract with a local business could create the company's Google+ Local page and step away from it. Of course, it's the ideal that your clients are actively posting to their Google My Business page, if it's the right social strategy for them, but many clients don't do this. And so, they'll likely be getting an email from Google one of these days asking if they are still active. If that's the case, you may be hearing from past clients asking if the email is real and what they should do. Fortunately, they should be able to make the the quick visit to the dashboard without help. But for agencies with large numbers of long-term clients, this business of keeping track of how often you've logged into the clients' dashboards could be a bit of a hassle. Just one more task to add to the to-do list.
Google has been going through some growing pains recently. With the lock-down of the editing function on Mapmaker and the further removal of Google+ links from more places, many Local SEOs and local business owners are wondering where Google is headed in the local space. To my mind, the fact that they are trying to police active vs. neglected listings is a bit of a sign the Google remains serious about delivering Local quality. And for all of us ... that's a good thing!
