Stop Counting Clicks | UX Booth

The 3-click-rule is the Freddy Kreuger of web design advice. You think it’s finally dead and then it comes back and starts slashing up sensible debate about usable design. I’m hoping to convince you to stop talking about the 3-click rule. I don’t mean substituting it with the 4-click rule or the 5-click rule. You should stop counting clicks as a measure of usability altogether.
