In the study presented in this paper we investigate how variations of information scent of hyperlinks of a webpage influence usersʼ behavior in terms of attention-focusing, confidence, effectiveness and efficiency, while exploring a website. In the reported study, 19 participants completed eight different tasks associated with eight simplified websites. Analysis of the results showed that even small differences in the target-linkʼs information scent can substantially affect usersʼ performance, distribution of attention and confidence. The study contributes to the related literature by quantifying the impact of even small differences in the target-linkʼs scent on usersʼ success ratio, time for first click, confidence and distribution of attention. In addition, a scent threshold value was identified, below which all the measured variables were substantially affected, and thus the link could be characterized as of “weak scent”.Tselios N., Katsanos C., Avouris N.
