Information searchcan be casual (reading ads and articles that happen to catch your attention) or formal (searching for information in publications such as Consumer Reports). Advertising helps the search process by providing information that is easy to find and
remember. For low-involvement products this stage may not occupy much time or thought
or it may be skipped altogether. Another way to describe consumer behavior in terms of information needs includes such terms as searchersandimpulse buyers.Searchers are driven
by a need to know everything they can about a product before making a purchase, particularly major purchases. In contrast, people who buy on impulse generally do so without much
thought based on some immediate desire such as thirst or hunger. Usually there’s not much
at stake, so the risk of making a bad decision is much lower. It is true, however, that even
major purchases, such as cars, can be made on the spur of the moment by people who are
not dedicated searchers for information
