Information search and decision making. Consumers engage in both internaland external information search.
Internal search involves the consumer identifying alternatives from his or her memory. For certain low involvement products, it is very important that marketing programs achieve “top of mind” awareness. For example, few people will search the Yellow Pages for fast food restaurants; thus, the consumer must be able to retrieve one’s restaurant from memory before it will be considered. For high involvement products, consumers are more likely to use an external search. Before buying a car, for example, the consumer may ask friends’ opinions, read reviews in Consumer Reports, consult several web sites, and visit several dealerships. Thus, firms that make products that are selected predominantly through external search must invest in having information available to the consumer in need—e.g., through brochures, web sites, or news coverage.
