Investigate SEO issues with subdomains #838
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.cc.org, ccsearch.cc.org, network.cc.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.
