Great points all Colan. That's what I would do too!I second everything Linda says. I also do competitive analysis to see what competitors are targeting and what they are ranking for.
You can scan your competitors categories by researching on Map Maker.
Also, now you can see 5 categories associated with any G+ Local listing (not necessarily what's in the dash) by clicking "Edit Business Details" right on the listing. This is brand new as of last week. Linda broke the news on this thread:
Google+ Local - Category Bug Bites Listings - Page 3 (warning, this thread is a doozy, with a ton of info)
I would think Google would see Attorney and Lawyer as synonyms, so not sure both would be needed.If you're dealing with a lawyer, can you have two different but similar categories?
I.E. Divorce Attorney Divorce Lawyer
Or would you advise sticking with just one? There are tons of Google+ Local results for both terms so I was thinking I should use them both - but not sure if that would violate any Google rules.
Colan, just out of curiosity can you check some of your listings and try clicking on the actual categories that are showing? What I'm seeing now for one of my client's listings it that when you click on the category names that are visible, the others show up without having to click "edit details...)Also, now you can see 5 categories associated with any G+ Local listing (not necessarily what's in the dash) by clicking "Edit Business Details" right on the listing.
