So we all know how important the Domain is for SEO. My question is about saving money by not having to buy 100 domains if i want to launch 100 sites.. Lets say i find a good / short .com.net.org domain (4 letters or some words that google doesnt count when searching (and, of, on, the, who)) and then use exact subdomains for my sites. How much will this make it harder compared to having exact domain match? example: mobilephones2011.com/net/org vs mobilephones2011.thewho123.com/net/org Thanks for your help.
