On my site I have setup Google authorship for myself. I have 3 other bloggers on the site which I pay to contribute quality relevant content for my site every week. I own the articles but the bloggers who do write for me maintain their writing credit.
Should I setup Google authorship for the writers on my site? I would think it would help with SEO, if not now I would think in the future.
My only concern is that Google authorship doesn't necessary mean ownership.
I also plan to setup a Google+ Business Page and be a Publisher. Would I be better to do this and leave my bloggers out of it?
