I have News Website and I have G+ page for it, I want to know that as I am using G+ page in "rel=publisher", now same page can I use in "rel=author" tag ?
Edwin Jonk: You can use them together. However the rel publisher only needs to be on the home page. While the rel author should only be used on psges like articles (not on product pages for example). Also a site can have different rel author on different pages while the rel publisher should be the same.
