The 3 click rule is an unofficial rule in web design that states when a user arrives at your site, they should find the information they’re seeking within 3 clicks of the mouse. The underlying concept of the 3 click rule is that users will start to become frustrated and leave a site if they have to click through several pages to find information.
The 3 click rule, in its strictest sense, has been successfully debunked as a “myth”. Studies illustrate that a website’s content dictates the optimal framework for its presentation. However, the 3 click rule – in a more abstract sense – embodies a general approach to developing concise navigation and clear site structure that would allow users to easily and intuitively locate information.
