My image traffic has taken a bit of a dip since nov 16th(late 15th) and while trying to find a possible cause there doesn't seem to be one in my rankings/average positions of images etc.
In looking up each of the images that lost the most traffic I find that the images don't appear until below the first group of sites which is often the same site taking up all positions (e.g. youtube etc). The thing is that it's fluctuating a great deal between images being shown BELOW the first 8 results and ABOVE the first 8 results.
Obviously my images do well when they are at the top of the results. Is this a change in Google layout that isn't done propagating or are fluctuations the new norm? Was there an announcement from Google on the 15th or 16th?
