I'm looking at how best to launch a project using subdomains to create around 10 'minisites' of sufficiently differing content using the subdomain as branding. There will never really be much content whatsoever on the main domain, it will only act as landing page for the subdomains with some aggregate content.
Are there any pitfalls I need to be aware of with this approach? I assume I should set canonical link tag to subject.domain.com and add said address in webmaster tools, repeating the action for further subdomain minisites as they're added? With this approach I will never really have much content on the main domain, it will only act as landing page for the minisites with some aggregate content.
Thanks very much for advice. While this is my first question here I'm seasoned on SO so not liable to hit and run.
