I have purchased 3 domain names, all variations of each other. For the best SEO should I put them on separate servers and accounts and just do a simple re-direct or just put them all on same provider. I have 4 different providers so it is no issue to have them separate. Next, should I set them up as plain re-directs or create landing page for browser to click on link to go to main page. Would appreciate any input on how to set this up for best SEO results.
