Ok. That makes sense. The way our company would use it is having a microsite for specific, focused topics - large enough that warrant their own site. They are clearly part of our overall brand, unlike the Disney properties example. On each of these sites, there will almost always be a link back to the main/corporate website, usually in the footer.
Do you think having one or two links on every page pointing back to company.com would be sufficient to notify search engines that the two are associated, and ultimately give some search value to the subdomain hosted microsite from the main domain?
Are there any studies or evidence supporting any of this?
