So look. how would you SEO your domain in the following situation: You have a business, its call 'Roy computer'. now, you want to buy domain names that have your business related keywords in them. for example: buycomputers.org and the purpose of you buying that domain - is to SEO it, hope it will gain SERP, and redirect it to your actual business website: 'Roy computer'. So now* my question to you: how would you SEO the other domains that are redirected to your website? directory submisions? that woudn't work because there is no real content - directories woudn't accept you?. i know its a little hard to understand because im giving a weird example. Thanks for the help!
Without content (and really unique content) for your other websites, I do not believe that you will succeed in your SEO effort. There is a lot more to SEO than just the domain name of a web site. Redirects are not going to cut it. Sorry for the bad news, but it is going to require effort.
Domain name is not the final line in SEO, you can have a domain name without one single keyword and still rank #1 for your required SERP. It's all about the backlinks, use anchor text backlinks of the keywords\phrases you want to rank for.
The only time that practice yields advantage is if the domains you redirect already have IBLs. This in turn implies (if only to a minor degree) that they had content. In a nutshell, either buy expired domains with IBLs, or buy new ones, develop them as sites, acquire backlinks for them, then redirect after maybe 6 mths. Hope that helps.
I wouldn't do anything else with the domains that you are redirecting. However, if you have buycomputers.org - you can build a mico site on a different IP and link the pages into roys computers.
Thanks for all the help guys!. I came to the conclusion that it will be smarter to buy 'keyword domain' - get people to write a keyword rich articles, and direct links back to my business's domain - improving its SERP. I think that will work nicely. what do you think about that?
