How can I redirect many websites to one domain without hurting SEO?

[rubyjean]

If anyone know explain please.

 

[Biggie]

the domain that receives the traffic, shouldn't be affected
the others prolly won't sustain any rank they have

but who knows.... when only google holds the controls

imo...

Hard to say on most SEO these days, Google keeps changing the formula, but without content, the domains will most likely be de-ranked.
