The more people recommend the links that appear on Google +, more weight will have on the results pages. The user preferences are a new factor to consider when positioning. People are saying now what are the best links, where to find the best information, and so on. No it only works for browsers, but readers are becoming increasingly important.

The most relevant profiles will be giving greater weight to the links posted on their walls. That is to be relevant to Google Plus to end up being more important than to be on Twitter, at least from the standpoint of positioning. You should mindful of this item!
