How many times has a client or stakeholder told you that it takes too many clicks to get to a page? Or that they heard that users give up after 3 clicks?
Free Usability Advice has a handy article about this long-standing myth.
I love the idea of calling something like this a ‘false metric’ (sounds so much better than ‘a bunch of baloney’):
The 3-click rule also is what we call a false metric. Making pages accessible within 3 clicks has no inherent value as a metric to the users of a site or to your business goals.
This will go nicely alongside my rebuttal to the argument that users don’t like to scroll.
