Welcome to the Q&A Forum

great information here guys. Phil some of the info you have put out has been extremely helpful. We a client whose video producer published the video to Vimeo plus ( I know Vimeo Pro is much different) and subsequently has created the 3rd strongest listing for their name. Even though the video has been removed from Vimeo for 2 months it still ranks very high. What I've taken away from this is make sure whoever you're working with is using a business-class video hosting platform and does not publish work to something like Vimeo a service I feel is equal to YouTube in many ways ( aside from their Pro feature which will allow somebody to host a video appropriately.) Thanks for all the info, Thomas

If the blog posts have true value and if there has not been a big investment in offpage SEO, I would simply move them to the primary domain. That will be a big increase in benefit over what you currently are getting. If you can figure out a way to canonical or redirect that will be a huge bonus as long as you have not built spammy links.
