Eyetracking Study

What and how are you looking at websites? That's exactly what researchers were looking at in 2006 under the guidance of Jakob Nielson's eyetracking study. Interestingly enough the study found that people tend to look at information in "F" formations or patterns on websites. This might explain why it's preferable to place navigation on the left side of the screen and logo's tend to be placed in the upper left corner of the screen.
