I have been using market samurai for looking at my competitors link profile and one of the biggest ones seems to be buying websites to add link content to. Is this a good method?
I know you can buy high pr expired domains but I have found this not to be so good as once you change the pages and content the pr drops back to N/A.
But how would you go about buying websites that have pr and are still working. I'd think the complications of transferring it would be difficult.
