Investigate SEO issues with subdomains

[little-wow]

Best practice for SEO says to use subfolders rather than subdomains, but for CC historically, subdomains have been a method of organizing the site (see: search.creativecommons.org, ccsearch.creativecommons.org, network.creativecommons.org, etc.)

"Search engines keep different metrics for domains than they do for subdomains, so even though Google itself has stated that — from a ranking perspective — content in subdomains and subdirectories is treated roughly equally, it's still recommended that webmasters place link-worthy content like blogs in subfolders rather than subdomains (i.e. www.example.com/blog/ rather than blog.example.com)."

Because we don't have competitors in the space or similarly named organizations, I think we should be fine, but I don't want to muck up our search rankings by creating a bunch of subdomains or maintaining historical subdomains for no reason.

This is particularly important because of the new network sites coming online. For this reason, I am tagging @robinpuga @robmyers @ericsteuer @pa-w

We currently only use subdomains for different sites (ex. blog.creativecommons.org redirects to creativecommons.org/blog/). I am not aware of any plans to combine sites (with the exception of moving the chooser from beta-chooser.creativecommons.org back to creativecommons.org/choose).
