Abstract
This paper examines how the number of information cues in recommender systems influences consumer search and purchase. E-commerce platforms often display a list of recommended products on product pages, where consumers can browse and click on individual items for details. Given space constraints, determining the appropriate amount of information to display is crucial, as it affects consumers’ use of both recommender systems and non-recommender search tools. Through a field experiment with an online retailer, we test four information designs: no cues (product name only), single cues (either price or review), and dual cues (price and review). We find an inverted U-shaped relationship between the number of information cues and sales, with single cues yielding the highest sales compared to both more (dual cues) and less information (no cues). This nonlinear effect stems from the interplay between search intensity and efficiency. The no-cue condition increases search intensity but forces consumers to rely on a less efficient non-recommender search process. In contrast, the highly efficient dual-cue condition provides sufficient information for evaluation but discourages further exploration beyond recommenders. Single cues strike a balance, offering just enough information to aid product evaluation while maintaining high search intensity across both recommender and non-recommender tools.
