How important is it to be on G+? Will Google penalise me for not being on Google+?
As of now, it is not really possible to prove that Google+has a heavy impact on non-personalized results. However, Google+ posts themselves can rank in search engine results, and Google+ is a network that continues to grow; that said, don’t worry about Google punishing you if you choose not to create a page on Google+! However, we strongly recommend it, because it will definitely not hurt you to have one, and we can only imagine what big plans Google has for this platform in the future. Better jump on the bandwagon sooner rather than later!
