The following is a special report from SMX West 2009.
First up Peter Linsley of Google ran through some of the concepts behind Google images and also factors that may influence ranking of images on Google which included some of the following:
- Number of referring sites—so whether the image is used on more than one website is a key metric in Google’s ranking Algorithm.
- The text around the image and the kind of words contained is also a factor taken into account by Google.
- Also placement of image—and whether it is above the fold
Peter also suggested that other dynamic features were in play. For example can a user comment on the image via a comments box? Or whether the image could be rated somehow.
