Good point about it being "google", Kelly.
Having a G+ page cannot hurt your sales in any way. My ability to target specific demographics that have demonstrated an interest in blacksmithing is a huge plus. You cannot do that on etsy.
To compare numbers:
Etsy = 15 teams with 19,797 members.
G+ = 19 "communities" with 55,000 members.
Etsy views are below 2,500 total since I started in February.
G+ views are over 19,500 since starting this month.
When I first started getting into the discussion forums, folks told me that I needed to network and join as many teams as I could because that would help me get noticed. According to my stats, the response has been mediocre, at best, and hasn't resulted in any sales.
Of the 10,000 teams on etsy, I only found 15 that I felt were a good fit for me and my product because 9,500 of those teams are one woman shows or haven't had a new post in months. The other 400 and some teams were specific to a certain type of seller (usually a city, state or women). So, really, there aren't that many teams for a guy to join. No sense in joining a team that only have three members and no traffic, right?
Anyhow, posting regularly on those 15 teams has amounted to no real boost in my numbers, and certainly no sales.
The same effort spent on G+ netted me 19 communities, and I had to cut my search short because there were simply too many options. Now I'm busy building my brand and developing relationships on those boards.
