When we wanna compare (sub)domain co.cc and co.tv we must considering some features, but SEO ability is the most important one. My friend told me that if we use non country which is TLD's such as .net .com or .org we can optimize the keyword for this domain easier than country domain names, such as .info. So I think (sub)domain co.tv better than co.cc when we want to optimize a keyword with both SEO strategy which is on page SEO and off page SEO. Take a look at this example; if we have highheels.co.cc and highheels.co.tv then we're really want to hit the main keyword "high heels" I think we should choose highheels.co.tv for better SEO optimizing. Because with co.tv (non country domain) we can win keyword including long tail keyword faster than if we use co.cc (country domain). But if we have highheels.co.tv and highheels.com (who's the owner?), absolutely we should choose highheels.com (yeah everybody know it). You got that? What do you think?
