Hello all,

What if a company which owns some portals, all with a lot of traffic and with an high PR, decides to "transfer" all the singles domains of the network under an unique domain, creating in some way an "unique great portal"?

I think that all the actual single domains will have a 301 permanent redirect, this would allow to the main domain to gain the PR and the link popularity coming from the old domains, or not?

Finally: what could it be the pros and cons of that kind of operation? Some suggestion too?

Many thanks
