Google plus is powerful social media works and also one of the best social media optimization. And that all this tabs like a link section, images, video, text, and events sections I really like it and enjoy it. And communities section also best you select your category related topic and promote your website very easily. And talking about hangout one of the best features you know that and also useful to that discussion. And all that function I use it and really like it.
