Abstract:

Recent studies have shown that while the use of breadcrumb trails to navigate a website can be helpful, few users choose to utilize this method of navigation. This study investigates the effects of 'mere exposure' and training on breadcrumb usage. Findings indicate that brief training on the benefits of breadcrumb usage resulted in more efficient search behavior.
