How Little Do Users Read? (Jakob Nielsen's Alertbox)

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.

The only thing we've been missing is a mathematical formula to quantify exactly how much (or how little) people read online. Now, thanks to new data, we have this as well.

  • Obviously, users tend to spend more time on pages with more information. However, the best-fit formula tells us that they spend only 4.4 seconds more for each additional 100 words.
  • The formula in the chart above indicates that there is a fixed time of about 25 seconds, plus an additional 4.4 seconds per 100 words. (Of course, the numbers are not "fixed" in the sense that they're always the same — these are averages.)
