When purchasing multiple domain names for a single business website is there a way to use them to help improve SEO? Basically I am purchasing different variations of my main domain name, mainly for protection purpouses, but I have also been creating redirects on them, pointing towards my primary domain. I have added the domains to my hosting package as it is free but added no files at all, including sitemaps etc. I have also not submitted the domains to any search engines manually. What I want to know is whether what I am doing is fine or if there is something very simple that I am doing absurdly incorrect or simply being SEO ignorant? The domains have helped a little when customers have incorrectly types the .co.uk or .net versions of my site as they have been pointed towards my master site, but I feel there is something so much more that they could do for my website. I do however not wish to create any new websites. Can anyone please help?
