Hello guys. I really need ur suggesting in this. I am willing to open a blog about hot trends but the problem is I am confused with the domain name. Is it better to create a new fresh domain or to make a sub domain in my very 10 years old .com domain that i use it for my flash games site ? My old domain just a 3 random words does not have any meaning in it. The reason why im asking because you know that aged domain has its golden value in serp and it will help me with my duplicated content but dos it still effective when making a sub domain? any harm with it?
