It's even murkier than you realize!
We're going to have to break down in stages cuz I don't have time to explain it all now. Way too convoluted.
If I am to understand correctly, a Google Plus (personal) account is required prior to establishing a Google Local business page. It appears the best approach would be for me to establish a separate Google account on behalf of each of my clients. Or... would "claiming" and/or establishing Local pages under my Google Plus profile be a viable alternative?
So 1st off there are 2 DIFFERENT pages with the words "Google+" and "Local" in them and they are different. BUT since you mentioned setting up a G+ Profile it sounded like you were talking one thing, but in reality I think you are talking another.
Re claiming - ABSOLUTELY need to claim the Google Place page AKA Google+ Local page in different accounts. IF you claim them all in a master account you can end up getting all clients suspended and there is no easy way out. Also no easy smooth way to transfer listing to client if you part ways.
Hi Linda,
Yes... "murky" is nice way of describing the convoluted naming conventions!
Ultimately, I would like to follow whatever the current best practice in order to establish setting up a Place aka Local page (with review & social features) with the purpose of ranking in search. However... you added a yet a new twist I wasn't aware of (i.e. the necessity of merging with a G+ page) - I assume you mean G+ profile (the one a user receives when creating a Google account)? Please elaborate at your convenience.
Let's back up and start here to try to help you understand the different pages and options and see if that helps.
Crazy Google Local Page Name Conundrum - Clearing the Confusion
Then to cut to the chase - there are 20 other REALLY important things you need to know, but here are 3 I want to be sure you are aware of...
With the PLACE page. The page that shows in search and has the reviews... most businesses already have one, even if they never created one. So you need to know how to search and find and if there is more than 1 need to know how to pick the BEST one. So you should not create from scratch if there is already one out there. OR if the client already created a listing you need to get their login and use the existing account.
Point 2 is you should NOT create a separate G+ Business page (the one with social features) and manually merge them right now. Google suggests waiting until you get the new dashboard which is rolling out. With that dashboard there is a one button upgrade option. That's what Tony is referring to.
So if you are sure they don't have anything yet. Create new Google account with their profile. Create new listing in the Places for Business dashboard. If it's a brand new listing you should get the new dash, then can upgrade to Google+ if it gives you the option.
And last of all, some types of businesses don't even qualify to merge yet and are not supported.
It's super complicated and keeps changing. Doing it wrong for a client on Google can be like tying them up in knots and can be very hard to untangle. Lots of answers here that explain all the issues. But sometimes you have to dig a little to find the info.
