Hi, I have a site http://pcandweb.com , i'm going to buy another domain now i'm thinking should i forward the domain to pcandweb.com subdomain?, will it make pcandweb rank better? for example, if you go psdtuts.com , it redirects to http://psd.tutsplus.com/ so is it better or should i start another site separate from the main domain.
Personally I would not do that all my websties are on different IP addresses, if you put one on your main domain and the other on sub, they both will be on the same IP address and Google will penalise you for this.
seperate domain is the best solution.......................use seperate domains for your se rankings................................
its aboutt he same because a sub domain is considered a new site so you dont gain any value, your basically starting both off fresh.
