This study compares usability ratings of Web sites, based on academic research, to actual usage data, from Nielsen Online. This is accomplished by consulting academic usability research, and using those guidelines to rate eight retail Web sites on usability. Then, this study uses “real world” data, the usage data from Nielsen Online, to longitudinally validate the academic findings. Results show that, over time, the calculated usability ratings move in the same direction and in the same magnitude as the usage data.
