I own over 50 domain names but they are all on one server, if I set up a blog for each one and update it with links to sites that I am trying to build up will this be effective? Or would it be more effective to have the domains on different servers? thanks for your help
You will still get link juice from teh sites but like comusher said it would be best to have different servers. You dont want to look spammy
if you make it like a natural backlink you will be fine but if it is a link farm then you could be in trouble.
My dear friend There is nothing to add blog in each site on the same server. Goolge does not have any problem with this. But listen you will be in problem only when you interlink all these 50 domain to one another. Yes if you link all the blogs with external links (other than you 50 domain) you can get good vote. So dont worry carry on. cool mate Enjoy
