Google has been testing some new algos on a small subset of sites for some time, roughly since August I would guess? A very small number of sites have been hit hard with no explicable reason when compared to other sites in their niche. Some of these sites have returned in yo yo fashion, whilst others havnt.
I think we all may see the results of this quite soon, a big update is imminent?
