Can G spot a three way or tiered link? Will G see the following like a link exchange? For example say I have 4 sites A thru D and all in the same industry. A, B and D are all the same IP hosted in the UK and are all PR0. C is a different IP in the US and is PR1. A and B link to C - will G only credit A or B and not both as they're considered the same source? Any juice passed? C links to D - will G pass PR1 juice through to D? Advice?
