Google+ is much better because it provides dofollow backlinks if you share anything on Google+ .I have written an article on my blog about benefits of Google+ is would you like to read: h**p://technostics.blogspot.com/2012/09/how-google-plus-is-effective-for-bloggers.html Replace the * with t
I don't think so Facebook is facebook.. There are milions people out there.. if you get some of them you can get great traffic from it.. I think for me Facebook is Number 1.. Than google +
Just to shed light on this lunacy, Google was penalizing sites that had too high of a Google + exposure. Even Google penalizes people for using their own platform...Even when no one else is...It's hilarious.
I believe Google+ has more sway on the SERPs simply because Google has access to the data (because it's theirs). I don't think Facebook likes sharing too much info with Google, which limits the effect Facebook has on the SERPs. That is not to say that Facebook does not hold some sway on the SERPs. I believe the Google spiders can read how many likes a certain website page has, which could effect the SERPs. I'm not sure however, maybe someone from Google can chime in?
I don't think there is much difference but for SEO I'll prefer G+ as when you share or G+ some one's post Google shows them in search result when you search a relative keyword. So +2 for G+ and +1 for Facebook
Both are better for driving traffic to website. through Facebook we can drive traffic to our website by engaging user from different activities. through Google+ we can do same thing also we can do local business listing though Google maps.
Google+ is better in many ways. I think in webmasters tool they have an internal tracking mechanism. And count it to rank pages.
