A few years ago I came across a debate on another forum about using shared IP's for your websites affecting your SE rankings and the consensus seemed to be that this didn't matter. As I was using a shared IP on around 50 sites and had good rankings I tended to agree. The last 12 months despite my efforts some of my sites have sunk SE wise yet a few have P3 google rankings that are on the same IP. Thoughts? I am on a new host for my dedicated box and can get additional IP's for a lousy 2 bucks, but this issue seems to be fairly divided and any input would be appreciated.
