Consumer behaviour refers to the study of how people — either individually or in groups — select, purchase, use, and dispose of goods, services, ideas, or experiences to satisfy their needs and wants.
In simpler terms, it’s about understanding why people buy what they buy, how they decide between brands, what influences their purchasing decisions, and how they feel before, during, and after a purchase.
Definition
Consumer behaviour is the process and activities that individuals or groups go through when selecting, purchasing, using, or disposing of products and services to fulfill their needs and desires.
It includes not just the act of buying, but also:
-
The mental process of evaluating options
-
The emotional triggers behind decisions
-
The social influences that shape choices
💡 Key Elements of Consumer Behaviour
-
What consumers buy – the product or service they choose
-
Why they buy it – the motivation behind the purchase
-
How they buy – the process or channels (online, offline, etc.)
-
When they buy – timing and frequency of purchases
-
Where they buy – store, website, or marketplace
-
How often they buy – loyalty, repeat purchases, or seasonal buying
🔍 The Stages of Consumer Buying Process
Consumer behaviour typically follows five key stages:
1. Problem Recognition
The consumer realizes they have a need or a problem.
Example: “My old phone battery dies quickly — I need a new one.”
2. Information Search
They look for information about available options.
Example: Reading reviews, watching YouTube comparisons, or visiting stores.
3. Evaluation of Alternatives
They compare different brands, prices, features, and reviews.
Example: Comparing Samsung vs. iPhone vs. OnePlus.
4. Purchase Decision
They decide what to buy and from where.
Example: Buying an iPhone 15 from Apple’s online store.
5. Post-Purchase Behavior
After the purchase, they evaluate whether it met expectations.
Example: If satisfied, they may leave a positive review or recommend it to others.
