1.) Let´s say I blast a site with 1k backlinks with only my KW´s as anchors and 301-redirect it to my moneysite. As I understand it, with the link juice also the anchor text density will flow to my money site, so I should probably blast at least 5k backlinks with non-KW anchors to another site, which is also redirecting to my moneysite in order to keep the anchor density of my MS under 15%. Is that correct? 2.) What if I use a URL shortener as a redirect to my MS? Will the KW density as well flow to the MS? I know, it´s a 301, too, so probably the same rules apply. However, shorteners have the reputation of working as a filter for spam while letting the link juice through to the MS. Therefore I could imagine that a shortener could filter out the overuse of KW anchors, so that you dont have to worry about density at all. 3.) Same scenario, but instead of a 301 I am using a buffer site linking to my MS. Do I have to build 5k non-KW anchors, too?
