Impact Of Multiple Blogs
A client currently has their blog setup as a subdomain of their site, through blogger. We recommended moving the blog under their current site & cms, ie www.domain.com/blog. Price for the migration was too high for the client. Although I think I know the answer, and I don't think it's positive, the idea of starting discontinuing posting on the old blog and starting a new blog under the site crossed my mind. Essentially we would setup the new blog, post all new blogs there, and slowly, over time, the client would migrate the old blog posts over.
Will Google penalize the site for having both blog.domain.com & www.domain.com/blog even though there will never be any duplicate content?
