I am not sure whether this has anything to do with the Panda or Penguin however it is very evident that Google has a major problem with assigning an image to the correct website whereas Bing seemingly has little problem with either the original image or text.
I have quite a few hand-built gallery sites and obviously all these sites have images on them. Many of the images have been copied to death over the past 12 years or so and I do not rank for many of them now...my fault, I should have watermarked them from the beginning the same as I do with all my new sites these days, interestingly many of the sites that now beat me in the image SERPs are built on WordPress and Blogster sites.
I also have several blogs with many images on them and whilst none of the images are watermarked, and I'm fairly sure many must have been copied, I'm fairly sure that no one ranks above me for those images hosted on WordPress.
I found this out only yesterday, 1st January 2013, purely by luck when I saw one of my 10 year old images from one of my handbuilt galleries disappear and be replaced by an Indian July 2012 Blogspot site at #3 in images and displayed on the SERPs page at the top. This site has come from absolutely nowhere and, of course, is running AdSense, it certainly is not an authority site however every image on the site has been copied from mine but none of the technical data, only the images.
My question has to be is Google's Panda/Penguin giving blog sites priority over evergreen sites purely because of the date marking in blogs whereas probably on most older sites there is not one? Could this possibly be what their foul-up is all about and why it is that many of us keep seeing scrapers all over the place?
I have no idea whether I am correct or not other than it seems very coincidental that many of the sites I see with my copied images are on blogging platforms therefore I am going to take one of my older small sites, copy it into a WordPress blog on a completely new and unused domain and see what happens!
What do others feel about my observation?
Have you seen similar but it's never really registered or am I just going Gorg-crazy?
