Thanks for your reply
Basically all I really wanted to do is to have this domains in my possession in order to prevent someone else buying it. this is a first thing, now the second I have registered them separately and had them as a different account each one of them, then decided to redirect them all on to a main .com domain instead of them being there and doing nothing, but the minute I did this I have started to loose traffic on my main .com domain. NOw I have removed redirection and also moved all of the domain as aliases of the main .com domain as it was suggested to me by my server host, but still no sign of my traffic going back to normal.
Are you suggesting to actually do a permanent 301 redirect to the .com domain even if my .com domain is still going to be always used as a main one?
