Getting the first click right [Measuring Usability - Oct 19, 2011] – Few things affect task success more than the navigation of website. If users can’t find what they’re looking for, not much else matters. If it were easy to get the navigation right, there wouldn’t be books and a profession dedicated to it.
First impressions matter in life and that’s also the case with website navigation. Research has shown that when users first click is down the right path, 87% eventually succeed. When they click down an incorrect path, only 46% eventually succeed.
