Is it possible to build PageRank from engagement on Google+?
I`ve always thought that links from Authorship markup were a large part of helping Google+ profiles build PageRank. I look at examples of brand pages in the search marketing industry who are receiving a lot of mentions and engagement from influencers that have not built any visible toolbar PageRank. +Lee Smallwood
do you feel it`s possible to build PageRank on a profile or brand page exclusively from engaging and sharing on the network?
