i don't know if you had similar experience but recently i've found that many websites use parked domains without redirection. two examples that i remember are: http://xn----ylbandbmrbccr2ax8cfbiip9g.com/ (it's a domain with greek letters) http://www.kbit.gr/ http://www.freewha.com/ http://www.freewebhostingarea.com/ what i don't understand is why aren't they using 301 or 302 redirect? can they gain keywords from these different domains? for example if i had a domain drawcomics.com and then i parked readcomics.com, would i gain anything if i had the same content in both of these domains?
