Can a Marketing Mix Still Work When Consumer Behaviour Keeps Changing?

Consumer shopping habits change constantly. Younger shoppers may buy clothing through mobile apps, while older customers may visit physical supermarkets less often. These changes often make business managers question whether the traditional Marketing Mix is still useful.

Professor E. Jerome McCarthy introduced this framework in 1960, organizing marketing decisions around four key areas: Product, Price, Place, and Promotion. Although consumer behavior varies across countries and age groups, the Marketing Mix remains relevant because it helps businesses evaluate these four essential areas. To use the framework effectively, business owners must first understand how customers behave today.

How Brands Adjust the Product in the Marketing Mix

Indian biscuit brand Parle-G is a good example of how businesses adapt to changing conditions. Customers wanted an affordable everyday snack, so the company kept its ₹5 price unchanged for many years, even as production costs increased.

Instead of raising the price, Parle-G adjusted the product by reducing the number or weight of biscuits in each packet. The packaging and price remained familiar, so customers continued buying the popular yellow packets. This Marketing Mix decision helped the company manage rising costs while meeting customers’ expectations for an inexpensive snack.

Today, shoppers can compare prices across different websites within seconds, making fixed pricing less effective in some markets. To respond, many businesses use dynamic pricing, adjusting prices according to demand, competition, and customer behavior.

Airlines change ticket prices based on demand, while Amazon reportedly updates product prices millions of times a day. Algorithms monitor competitors and analyze factors such as shopping-cart activity. If a customer seems ready to buy, the system may offer a small discount to encourage the purchase. This flexible Marketing Mix helps businesses remain competitive while protecting their profits.

In the Marketing Mix, “Place” refers to how and where a product reaches customers. Today, many shoppers prefer not to travel long distances to physical stores. Research from McKinsey & Company suggests that omnichannel customers buy significantly more than those who use only one shopping channel.

Modern businesses combine physical stores with mobile apps and home delivery. Instead of relying only on a traditional shop location, they use local warehouses to store products and delivery services to bring orders directly to customers’ homes. The distribution principle remains important, but the shopping experience now often begins on a digital screen and ends with a package delivered to the customer’s door.

As we discussed in our recent article about Word of Mouth, modern shoppers often trust everyday content creators more than expensive television advertisements. Research from Nielsen highlights the strong influence of peer reviews and personal recommendations on brand trust.

An effective Marketing Mix adapts promotion to the platforms customers use most. Instead of spending heavily on newspaper ads, businesses may work with ordinary users or creators to showcase their products through short mobile videos. HubSpot’s video marketing research suggests that short-form videos can generate strong returns for retail brands. Businesses can still promote their products widely, but they now reach customers through more personal and targeted digital content.

Consumer habits can change quickly, but the four core business questions remain the same. Businesses must decide what to offer, where to sell it, how to communicate with customers, and what price to charge.

A strong Marketing Mix helps managers respond to changing consumer behavior by updating these four decisions when necessary. The framework remains stable, while the answers evolve with the market. By monitoring real customer habits and adapting their strategies, businesses can stay relevant and maintain steady revenue.
