This is my link piramid setup: Tier1 links consist of : web20 posts, 400 sponsored reviews, forum posts / profiles. Tier 1 links have around 20 diferent anchor texts like widgets, blue widgets, red widgets online, etc. All links in this tier have been indexed by G and are around 6-12 months old. Tier2 is: Xrumer blasts to Tier1. Each xrumer post has 6 - 10 links pointing to tier1 with also 20-30 anchor texts. So far i've build around 50 000 posts on tier2 and all i can see is DROP in the serps. Massive drop -100, the site had been sitting high in the serps for months. Any idea why it looks like my link piramid failed ?
