I am trying to get my client's Google My Business profile cleaned up and they have a big interest in showing up for local "3 packs" on SERPs. They have seen themselves included in these and want to maximize the times they show up there.
Re: Business Info
Means they can't list all the treatments in the listing as categories and they are not allowed to list them as part of the names of the spa.
What remains: specifying the treatments in scheme.org of their websites.
Not much but its a way.
