5 Eye Tracking Is homepage layout effective? What effect do blurbs on the homepage have compared to headlines? When is multimedia appropriate? Are ads placed where they will be seen by the audience? From http://www.poynterextra.org/eyetrack2004

6 Heat Maps This dominant reading pattern looks somewhat like an F and has the following three components: Users first read in a horizontal movement, usually across the upper part of the content area. This initial element forms the F's top bar. Next, users move down the page a bit and then read across in a second horizontal movement that typically covers a shorter area than the previous movement. This additional element forms the F's lower bar. Finally, users scan the content's left side in a vertical movement. Sometimes this is a fairly slow and systematic scan that appears as a solid stripe on an eyetracking heatmap. Other times users move faster, creating a spottier heatmap. This last element forms the F's stem.
