E-commerce shop owners often want to attract user attention to a specific product, to enhance the chances of sales, to cross-sell or up-sell. The way of presenting a recommended item is as important as the recommendation algorithms in gaining that attention. In this study we examined the following types of highlights: background, shadow, animation and border as well as the position of the item in a 5 × 2 grid in a furniture online store, and their relationships with user fixations and user interest. We wanted to verify the effects of highlighting on attracting user attention. Various levels of intensity were considered for each highlight: low, medium and strong. Methods used for data collection were both implicit and explicit: eye tracking, tracking cart’s contents, and a supplementary survey. Experimental results showed that a low-intensity background highlights should be the first-choice solution to best attract user attention in the presented shopping scenario, resulting in the best fixation times and most users’ selection. In case of highest-intensity animation, however, highlighting seemed to have negative effects: despite successful attempts to attract eyesight and long fixation time, users did not add the highlighted products to cart.
