We like to know your opinion about following problems: We have one site http://manausbooking.com and several other related domains with the same content like http://amazontoursmanaus.com or http://amazonhostel.com If you put the same content on different domains get the main domain punished by Google or Bing? What is more effective to push page ranking of each domain? a) same content on all domains b) forwarding with masking Thanks
If your all the websites showing the same work mean online booking, tours and travels, then i think you should redirect all the web's to a particular web. If you use same content on all websites then u will face the issue of duplicate content or may be penalised by google or other SE's. Hope redirect will work. May be i was wrong but i am also doing this. i already have 6 websites which targeted a single work and i am going to redirect all the websites on a particular website.
As @Devesh Sharma said, you better make redirection for all your domain to the particular website. Google hates duplicate content and will penalized your site.
