Buying behavior differs greatly for a tube of toothpaste, a smartphone, financial services, and a new car. More complex decisions usually involve more buying participants and more buyer deliberation. Figure 5.4 shows the types of consumer buying behavior based on the degree of buyer involvement and the degree of differences among brands.
Consumers undertake complex buying behavior when they are highly involved in a purchase and perceive significant differences among brands. Consumers may be highly involved when the product is expensive, risky, purchased infrequently, and highly self-expressive. Typically, the consumer has much to learn about the product category. For example, someone buying a new car might not know what models, attributes, and accessories to consider or what prices to expect.
This buyer will pass through a learning process, first developing beliefs about the product, then attitudes, and then make a thoughtful purchase choice. Marketers of high-involvement products must understand the information-gathering and evaluation behavior of high-involvement consumers. They need to help buyers learn about product-class attributes and their relative importance. They need to differentiate their brand’s features, perhaps by describing and illustrating the brand’s benefits through printed promotional materials or in-depth online information and videos. They must motivate store salespeople and the buyer’s acquaintances to influence the final brand choice.
Dissonance-reducing buying behavior occurs when consumers are highly involved with an expensive, infrequent, or risky purchase but see little difference among brands. For example, consumers buying carpeting may face a high-involvement decision because carpeting is expensive and self-expressive. Yet buyers may consider most carpet brands in a given price range to be the same. In this case, because perceived brand differences are not large, buyers may shop around to learn what is available but buy relatively quickly. They may respond primarily to a good price or purchase convenience.
After the purchase, consumers might experience postpurchase dissonance (after-sale discomfort) when they notice certain disadvantages of the purchased carpet brand or hear favorable things about brands not purchased. To counter such dissonance, the marketer’s after-sale communications should provide evidence and support to help consumers feel good about their brand choices.
Habitual buying behavior occurs under conditions of low-consumer involvement and little significant brand difference. For example, take table salt. Consumers have little involvement in this product category—they simply go to the store and reach for a brand. If they keep reaching for the same brand, it is out of habit rather than strong brand loyalty. Consumers appear to have low involvement with most low-cost, frequently purchased products.
In such cases, consumer behavior does not pass through the usual belief-attitude-behavior sequence. Consumers do not search extensively for information about the brands, evaluate brand characteristics, and make weighty decisions about which brands to buy. Because they are not highly involved with the product, consumers may not evaluate the choice, even after purchase. Thus, the buying process involves brand beliefs formed by passive learning, followed by purchase behavior, which may or may not be followed by evaluation.
Because buyers are not highly committed to any brands, marketers of low-involvement products with few brand differences often use price and sales promotions to promote buying. Alternatively, they can add product features or enhancements to differentiate their brands from the rest of the pack and raise involvement.
For example, take something as seemingly uncomplicated as wheat flour or oatmeal. To set its brand apart, Bob’s Red Mill adds an “honest-to-goodness” touch to all of the baking, grain, and cereal products it makes, using only the best nutritional whole grains and time-honored stone mill production processes. Bob’s Red Mill doesn’t sell just plain old flour. It offers “America’s Best Baking Flours,” nine varieties of differentiated wheat flours, ranging from Unbleached White Fine Pastry Flour and Super-Fine Cake Flour to 100% Whole Grain Organic Ivory Wheat flour. The same goes for its oatmeal—billed as the World’s Best Oatmeal—with 24 varieties ranging from Extra Thick Rolled Oats to High Fiber Oat Bran hot cereal to Organic Scottish Oatmeal.
Consumers undertake variety-seeking buying behavior in situations characterized by low consumer involvement but significant perceived brand differences. In such cases, consumers often do a lot of brand switching. For example, when buying cookies, a consumer may hold some beliefs, choose a cookie brand without much evaluation, and then evaluate that brand during consumption. But the next time, the consumer might pick another brand out of boredom or simply to try something different. Brand switching occurs for the sake of variety rather than because of dissatisfaction.
In such product categories, the marketing strategy may differ for the market leader and minor brands. The market leader will try to encourage habitual buying behavior by dominating shelf space, keeping shelves fully stocked, and running frequent reminder advertising. Challenger firms will encourage variety seeking by offering lower prices, special deals, coupons, free samples, and advertising that presents reasons for trying something new.
Now that we have looked at the influences that affect buyers, we are ready to look at how consumers make buying decisions. Figure 5.5 shows that the buyer decision process consists of five stages: need recognition, information search, evaluation of alternatives, the purchase decision, and postpurchase behavior. Clearly, the buying process starts long before the actual purchase and continues long after. Marketers need to focus on the entire buying process rather than on the purchase decision only.
Figure 5.5 suggests that consumers pass through all five stages with every purchase in a considered way. But buyers may pass quickly or slowly through the buying decision process. And in more routine purchases, consumers often skip or reverse some of the stages. Much depends on the nature of the buyer, the product, and the buying situation. A person buying a regular brand of toothpaste would recognize the need and go right to the purchase decision, skipping information search and evaluation. However, we use the model in Figure 5.5 because it shows all the considerations that arise when a consumer faces a new and complex purchase situation.
The buying process starts with need recognition—the buyer recognizes a problem or need. The need can be triggered by internal stimuli when one of the person’s normal needs—for example, hunger or thirst—rises to a level high enough to become a drive. A need can also be triggered by external stimuli. For example, an advertisement or a discussion with a friend might get you thinking about buying a new car. At this stage, the marketer should research consumers to find out what kinds of needs or problems arise, what brought them about, and how they led the consumer to this particular product.
An interested consumer may or may not search for more information. If the consumer’s drive is strong and a satisfying product is near at hand, he or she is likely to buy it then. If not, the consumer may store the need in memory or undertake an information search related to the need. For example, once you’ve decided you need a new car, at the least, you will probably pay more attention to car ads, cars owned by friends, and car conversations. Or you may actively search online, talk with friends, and gather information in other ways.
Consumers can obtain information from any of several sources. These include personal sources (family, friends, neighbors, acquaintances), commercial sources (advertising, salespeople, dealer and manufacturer web and mobile sites, packaging, displays), public sources (mass media, consumer rating organizations, social media, online searches and peer reviews), and experiential sources (examining and using the product). The relative influence of these information sources varies with the product and the buyer.
Traditionally, consumers have received the most information about a product from commercial sources—those controlled by the marketer. The most effective sources, however, tend to be personal. Commercial sources normally inform the buyer, but personal sources legitimize or evaluate products for the buyer. Few advertising campaigns can be as effective as a next-door neighbor leaning over the fence and raving about a wonderful experience with a product you are considering.
Increasingly, that “neighbor’s fence” is a digital one. Today, consumers share product opinions, images, and experiences freely across social media. And buyers can find an abundance of user-generated reviews alongside the products they are considering at sites ranging from Amazon.com or BestBuy.com to Yelp, TripAdvisor, and Epicurious. For example, Yelp’s goal is “to connect people with great local businesses” by maintaining a huge, searchable collection of candid reviews from people who’ve used those businesses. Over the past decade, Yelpers have written more than 90 million reviews of local restaurants, service business, arts and entertainment activities, and other service in cities across the nation. The site receives some 89 million unique visitors per month seeking reviews and ratings.29 Although individual user reviews at Yelp and other sites vary widely in quality, an entire body of reviews often provides a reliable product assessment—straight from the fingertips of people like you who’ve actually purchased and experienced the product.
As more information is obtained, the consumer’s awareness and knowledge of the available brands and features increase. In your car information search, you may learn about several brands that are available. The information might also help you to drop certain brands from consideration. A company must design its marketing mix to make prospects aware of and knowledgeable about its brand. It should carefully identify consumers’ sources of information and the importance of each source.
We have seen how consumers use information to arrive at a set of final brand choices. Next, marketers need to know about alternative evaluation, that is, how consumers process information to choose among alternative brands. Unfortunately, consumers do not use a simple and single evaluation process in all buying situations. Instead, several evaluation processes are at work.
How consumers go about evaluating purchase alternatives depends on the individual consumer and the specific buying situation. In some cases, consumers use careful calculations and logical thinking. At other times, the same consumers do little or no evaluating. Instead, they buy on impulse and rely on intuition. Sometimes consumers make buying decisions on their own; sometimes they turn to friends, online reviews, or salespeople for buying advice.
Suppose you’ve narrowed your car choices to three brands. And suppose that you are primarily interested in four attributes—price, style, operating economy, and performance. By this time, you’ve probably formed beliefs about how each brand rates on each attribute. Clearly, if one car rated best on all the attributes, the marketer could predict that you would choose it. However, the brands will no doubt vary in appeal. You might base your buying decision mostly on one attribute, and your choice would be easy to predict. If you wanted style above everything else, you would buy the car that you think has the most style. But most buyers consider several attributes, each with different importance. By knowing the importance that you assigned to each attribute, the marketer could predict and affect your car choice more reliably.
Marketers should study buyers to find out how they actually evaluate brand alternatives. If marketers know what evaluative processes go on, they can take steps to influence the buyer’s decision.
In the evaluation stage, the consumer ranks brands and forms purchase intentions. Generally, the consumer’s purchase decision will be to buy the most preferred brand, but two factors can come between the purchase intention and the purchase decision. The first factor is the attitudes of others. If someone important to you thinks that you should buy the lowest-priced car, then the chances of you buying a more expensive car are reduced.
The second factor is unexpected situational factors. The consumer may form a purchase intention based on factors such as expected income, expected price, and expected product benefits. However, unexpected events may change the purchase intention. For example, the economy might take a turn for the worse, a close competitor might drop its price, or a friend might report being disappointed in your preferred car. Thus, preferences and even purchase intentions do not always result in an actual purchase choice.
The marketer’s job does not end when the product is bought. After purchasing the product, the consumer will either be satisfied or dissatisfied and will engage in postpurchase behavior of interest to the marketer. What determines whether the buyer is satisfied or dissatisfied with a purchase? The answer lies in the relationship between the consumer’s expectations and the product’s perceived performance. If the product falls short of expectations, the consumer is disappointed; if it meets expectations, the consumer is satisfied; if it exceeds expectations, the consumer is delighted. The larger the negative gap between expectations and performance, the greater the consumer’s dissatisfaction. This suggests that sellers should promise only what their brands can deliver so that buyers are satisfied.
Almost all major purchases, however, result in cognitive dissonance, or discomfort caused by postpurchase conflict. After the purchase, consumers are satisfied with the benefits of the chosen brand and are glad to avoid the drawbacks of the brands not bought. However, every purchase involves compromise. So consumers feel uneasy about acquiring the drawbacks of the chosen brand and about losing the benefits of the brands not purchased. Thus, consumers feel at least some postpurchase dissonance for every purchase.
Why is it so important to satisfy the customer? Customer satisfaction is a key to building profitable relationships with consumers—to keeping and growing consumers and reaping their customer lifetime value. Satisfied customers buy a product again, talk favorably to others about the product, pay less attention to competing brands and advertising, and buy other products from the company. Many marketers go beyond merely meeting the expectations of customers—they aim to delight customers.
A dissatisfied consumer responds differently. Bad word of mouth often travels farther and faster than good word of mouth. It can quickly damage consumer attitudes about a company and its products. But companies cannot simply wait for dissatisfied customers to volunteer their complaints. Most unhappy customers never tell the company about their problems. Therefore, a company should measure customer satisfaction regularly. It should set up systems that encourage customers to complain. In this way, the company can learn how well it is doing and how it can improve.
By studying the overall buyer decision process, marketers may be able to find ways to help consumers move through it. For example, if consumers are not buying a new product because they do not perceive a need for it, marketing might launch advertising messages that trigger the need and show how the product solves customers’ problems. If customers know about the product but are not buying because they hold unfavorable attitudes toward it, marketers must find ways to change either the product or consumer perceptions.
