Towards the tail end of PubCon, I noticed a spate of articles talking about subdomains and subdirectories in Google, and I wanted to talk more about this subject in case I was unclear.
Historically, it’s been kind of a wash about when to use subdomains vs. subdirectories. Just as a reminder, in a URL such as subdomain.example.com/subdirectory/ , the subdomain is “subdomain” and the subdirectory is “subdirectory” (also sometimes called a folder). If you’re still unclear, you may want to read my tutorial on the parts of a URL.
