Lets say I manage 8 websites for our company. Only a couple are in the same nitch so I have 2 in one nitch and 6 that are all different.
I built our CEO as the main Google + page years ago so he would be the author for all out content.
My question would be adding the rel=author I would use our main Google + page, but the links to the Google + should go to pages I have built under the main page?
Example we have a LMS for schools so the author tag will be the main page but the Google + button should go to a school information page I add info for schools.
and
We have a LMS for trucking so the Google + author tag would be the same tag on both sites, but the Google + link should land on a page built for trucking. This way I can also claim publisher for the content on the sites, correct.
Then for the LMS website I would do the same and so on. So in effect I would have one main Google + to be the author for all the sites, and 5 or more pages under my main Google + page to claim publisher
This way the content I post per website the Google + landing page would be relevant to the content within the website.
