In my scenario, I have one design website and three blog websites about specific types of design. I may also create a blog for the home page of the primary design website, too.
With respect to getting the best possible search engine rankings, would I be better served to combine these into one website containing three blogs? Or should I leave each of them as separate sites, each with its own domain name and simply link between
the sites? Also, if I should leave the sites separate, then I am thinking that I should either create a blog or a news feed for the primary home page of the design site. Am I correct in thinking this way?
Thanks for any help.
