i've got a new coporate client with a pretty heavy duty site, currently sits at PR4. they dont have much content or backlinks, but they are a brand name. I asked their IT head if they have a blog, and she told me that they do, but its hosted on a seperate nameserver and while it's techinically a subdomain of the main site, for all intents and purposes its a stand alone blog. my question is, do i ask them to move the blog and make it a part of their current site (a difficult task for them), or do i promote the blog seperately and just keep linking to the main site? its worth noting that without the blog, there isn't much new content on the site everyday. its pretty static.
