Which methods do you use for disversify your backlinks? You just take a look on the pagerank? Or do you disversify more with assumptions of the trustlink? And can you really build high class backlinks with blackhat? For example: I have 1000 Blog comments on PR3 domains but always URL PR0-PR1 sites. Also i have 4000 xrumer profile backlinks with PR0 but there is a funnel to this backlinks (30k BL on 16k backlinks on 4k backlinks). But still PR0... I created some forum postings on PR9 forums but just found URL PR0 sites. So if i just go for PR i definitly need now some URL high PR backlinks. What are you recommending?
