Search products or services have attributes customers can readily evaluate before they purchase. A hotel room price, an airline schedule, television reception, and the quality of a home entertainment system can all be evaluated before a purchase is made. Well-informed buyers are aware of the substitutes that exist for these types of products and thus are likely to be more price sensitive than other buyers, unless there exists some brand reputation or customer loyalty. This sensitivity, in turn, induces sellers to copy the most popular features and benefits of these types of products. Price sensitivity is high with respect to products with many substitutes, and since most buyers are aware of their alternatives, prices are held within a competitive band.
