I understand the idea behind tier linking. Create a buffer around your moneysite of tier1s, then semi-ok content for tier2s and last everything and the kitchen sink (spam) for tier3s. Would adding a higher quality tier help? Or would it dillute linkjuice to your money site? I was thinking for my tier1s, I create about 6-10 pages manually and schedule 1-2 posts a month to be automatically published. For tier2s, use Best Spinner to create articles with uniqueness at around 90.And use for Article sites, web2.0 and document sharing sites Then tier3, would be the traditional semi-ok content And last tier 4 would be the spam. I'm in it for the longterm so generally I'm not worried about quick results.
