Guys I have xxx.com and now it want to add abc.xxx.com how many of you think it will be a good Idea.First let me clear that xxx.com is education site and abc.xxx.com will be a book store for students. Do you think it will gonna work or should I go for some other strategies.
It would be better to put a sub directory instead of sub domain. Its purely depends on our requirements and our business plan.
yeah I guess you are right @jopsons ...What strategy you will suggest to rank categories of a website ..
