My infographic about the ranking factors for Google images search (2012) is old so I made a new one. This time I tried to make it more simple that those who have no idea about optimizing images for Google could also get an impression. What is really important, and what is only a „marginal factor“? The main question behind the infographic is: How could my image get a good ranking in Google Image Search?
Here it is – feel free to share and discuss …

To make this clear: duplicate content of images (that means copies) is an important positive ranking factor :-)
I made some things more simple than they are. Of course seo for images is more difficult. The goal of this graphic is to give an introduction of the main principles. Google gives very rarely information about image search and the ranking factors. So this is based on many tests and a lot of experience with a lot of gallery. But of course a I may fail. So please give me and others a hint if you observed something different – or if your theory about Google image search is another one :-)
Here the german version.
