I forget to look often enough at the studies done by or reviewed by Jakob Nielsen. I was reminded today when we discussed where to place links on the library website to our Research Guides (libguides).
From one of the more recent alerts:
How Little Do Users Read?
"On the average Web page, users have time to read at most 28% of the words during an average visit; 20% is more likely.
We've known since our first studies of how users read on the Web that they typically don't read very much. Scanning text is an extremely common behavior for higher-literacy users; our recent eyetracking studies further validate this finding....
Among other things, the authors found that the Back button is now only the 3rd most-used feature on the Web. Clicking hypertext links remains the most-used feature, but clicking buttons (on the page) has now overtaken Back to become the second-most used feature. The reason for this change is the increased prevalence of applications and feature-rich Web pages that require users to click page buttons to access their functionality. "
Oh, and the original reason for looking at Nielsen's site was to find the information about usability tester numbers. See
