Consumers can first be influenced by the situations surrounding their purchases. There are 5 different situations which pose an effect on consumer behavior; purchase tasks- the reason the consumer is shopping, social surroundings- who the consumer is shopping with, physical surroundings- the lighting, volume, crowds, etc,temporal effects- the time of day or amount of time the consumer has, and antecedent states- the consumers mood, amount of money on hand, etc.
The act of making a purchase is an obvious component of consumer behavior. What we cannot always see is the decision process that takes place in a consumers mind. This process that takes place is referred to as the consumer purchase decision process which refers to the stages a consumer goes through in making a buying decision. The stages of the consumer buying decision process are as follows:
Step 1: Problem Recognition- consumers identify a product or service that they may need and are compelled to satisfy this.
Step 2: Information Search- consumers conduct both internal searches- recalling their memory for previous experiences with certain brands, and external sources- gathering information about a product or brand from the internet, peers, salespersons, etc, to help sway their purchase decision.
Step 3: Alternative Evaluation- in this step of the consumer buying decision process the value of the product or service is addressed and alternative brands or resources known as the consideration set are identified.
Step 4: Purchase Decision- the consumer makes a decision about what product will deliver the most value to them and purchases that product.
Step 5: Post-Purchase Evaluation- upon use of the product, the consumer decides whether they are satisfied or dissatisfied with their purchase.
The post-purchase evaluation is extremely important to companies in demonstrating the level of customer satisfaction with the product. If a customer is satisfied with their purchase, they will tell 3 people about it, however, if the customer is dissatisfied with either the product, service received, or both, they will share this news with 9 people. This type of word-of-mouth or buzz marketing, is extremely important to the future of a product.
If a customer is unsure whether they are satisfied with the decision that they made, for example they purchased the new Windows phone instead of the new iPhone and are debating whether or not they made the right decision, they are said to be experiencing cognitive dissonance, or post-purchase anxiety. Once a customer has experienced cognitive dissonance from a purchase of a specific product, is hard to regain their brand loyalty. This is why in the more expensive and long-term purchases, known as extended purchases, through which consumers go through each stage of the consumer buying decision process, a high-involvement marketing strategy is employed using comparative ads (like the one shown below) and focused personal selling to help "seal the deal" for consumers.
