It is not an exhaustive exploration that we can extrapolate to the larger population. It is a mix of "findings" based on controlled variables, and "observations" where testing was not as tightly controlled. The researchers went "wide," not "deep" -- covering a lot of ground in terms of website design and multimedia factors.
The eyes most often fixated first in the upper left of the page, then hovered in that area before going left to right. Only after perusing the top portion of the page for some time did their eyes explore further down the page.
Dominant headlines most often draw the eye first upon entering the page -- especially when they are in the upper left, and most often (but not always) when in the upper right.
This "heatmap" generated by Eyetools software from the Eyetrack III study shows aggregate eye fixations and viewing of a news website homepage.
