Welcome to the Q&A Forum

Currently Google Authorship only supports one author per post as far as SERPs go (http://googlewebmastercentral.blogspot.com/2013/08/relauthor-frequently-asked-advanced.html) but I would recommend adding bylines for all authors on a post so if/when Google allows for multiple authors you have everyone show up there. Does this company page get considered as author? Technically no. Authorship is meant for individual people whereas Publisher is meant for Brands. However, Publisher may show up withyour Google+ logo if a person who follows you is signed into their Google Plus Profile.  You should have set up rel=publisher to identify cardekho as the publisher of the site and whomever is the author should have a byline.  If there are multiple authors then each author should have a byline.  Google will only support one image in the SERPs however and it will generally be an author. Would this company profile marked as rel=author help in any ranking benefit as an individual Author profile helps in search results? Again this should be a rel=publisher schema markup issue.  Having authorship show up in search results does tend to lead to higher click through rates but for pure ranking factor as related to Authorship, I think the jury is still out.  I still think domain level metrics are more important then author stats.

Hi, there are lots of experts you could call on to help you. I don't represent Moz, but speaking independently my best advice for a pool of companies you could contact would be to look at the Moz recommended list of companies and speak to some of them. You can see the list here: http://moz.com/community/recommended I hope that helps, Peter

I agree with everything John shared but wish to clarify one point: We want to run multiple blogs on different categories If the categories are different but related, then I prefer John's approach. If you have a site that talks about "cars" and you want to offer a "Ford" directory, a "Toyota" directory, and so forth then I prefer the approach John shared. On the other hand, if the categories are completely unrelated, then I would recommend using the subdomain approach so each domain can keep their focus. If one blog talked about cars, the second was about diabetes, the third was about poker, then these blogs clearly lack a uniting theme. To help each domain remain relevant for their primary topic, I would suggest using different sub domains.
