From yesterday Google pages are alive! Everyone can see the resemblance with Facebook pages, and so is expected to appear soon ignited a rivalry between Facebook and Google on these page rank. However, a Fb page with 100 likes will be equal in rank to a G+ page with 100 1+ recommendations?
Well, but still to this "pretty much the same thing" are some differences as what G+ describes "Direct Connect". You need to add a snippet of code to your webpage, just after that your account is verified. It prevents G+ from too many different pages of one brand where you don't know which one is official) cool thing
If you are just a user , Facebook or G+ both are ok ,choose one and enjoy it . If you are just a seor , had better to register 2 of them , they will brings you more traffic .
