A trap in thinking one already knows the market

To enlarge an opportunity, the notes write, a marketing strategy has to start with an understanding of the market. Many business people, they say, are sure they already know everything about it, and think no further research is needed. The trap is that one must still check whether that knowledge is really complete, and, even if it is, whether buyers will take the idea, and how it should be carried to them. It is not enough to know which goods are traded; one has to understand the thoughts and feelings of the people who buy and use them, and answer with a fitting strategy.

Brand loyalty, as the words suggest, is the degree to which a person prefers a particular brand when buying, and purchases the same brand again and again — an attachment to the brand. A buyer whose loyalty is relatively high, they write, will promote the favored brand to people nearby, and will trust and buy a new product when it appears. A firm that has grown by word of mouth, they add, can be seen as one with many such loyal customers.

A satisfied buyer, and two kinds of loyalty

They offer a small case. A consumer, A, has used the products of an electronics firm, B, and was very satisfied with a smartphone: the quality, the ease of use, and the service all sat high. A then holds a favorable attitude toward B, and, when buying electronics later, skips the usual weighing of alternatives and the forming of new beliefs, and simply buys that brand. Loyalty of this kind, they write, can be read in two ways.

Behavioral loyalty is close to actual use and purchase, and shows up directly in a firm’s results. Attitudinal loyalty is a latent idea: the possibility that a favorable view will later become a result. In a second sketch, B already likes brand A and wants to spread word of it, and tells C about the product. C, who already thought well of the brand, then decides whether to buy. Here B is the behavioral loyalist, and C the attitudinal one. C’s turn toward a purchase, they write, also comes from the firm’s work — the good image it has built. As such latent buyers grow, behavioral buyers grow too, and brand value rises.

Inertial buying: the same brand, with little thought

Inertial buying is also called habitual buying, and is treated as a tendency to avoid variety. It is often set beside brand inertia, though the notes say there is a difference. In general it means buying the same brand again and again. A buyer with a low level of brand commitment, and high “brand support,” is called a habitual consumer. When brand sensitivity is high, repeat purchase of the same brand belongs with loyalty; when the buyer does not attach much importance to the brand, and sensitivity is low, the same repeat behavior belongs with inertial buying.

Prior research, they write, finds that a habitual buyer of a given brand does not try to explore or evaluate its particular traits in any detail, and does not spend much thought on which brand to choose. Inertia, in this telling, is the effect of a past brand choice on a present one, and it stresses the repetition of that choice. Even when brands inside a product category are differentiated, a person may habitually buy one brand, or several, inside the frame of a consumption habit, simply to reach a purpose. Inertial buying, they add, is not based on attitudinal loyalty. The buyer may have a positive attitude, or may, without much attitude at all, simply find that brand automatically activated as a means to an end.
