Simonson and Rosen's Influence Mix

[bbasujon]

Have you made any big purchases recently? Perhaps you bought a new laptop or tablet, or upgraded your phone? If so, how did you decide which model to choose?

People are increasingly turning to online reviews and social media before they make an important purchase. So, how should you take account of this in your marketing planning?

This article looks at Simonson and Rosen's Influence Mix. This helps you think about the impact of social media on your customers' purchasing decisions, so that you can develop a well-focused marketing strategy.

About the Tool

Itamar Simonson and Emanuel Rosen are experts in how social media is changing the way that people shop, by making other people's opinions more accessible.

In their 2014 book, "Absolute Value," they explain how the Internet is moving us towards an age of nearly perfect information. This allows people to predict, with great accuracy, what it would be like to own and use a product before they buy it.

Where people's purchasing decisions are strongly influenced by online reviews and peer-to-peer information sharing, you clearly need to take account of this in your marketing. However, customers don't assess all purchases in the same way.

Simonson and Rosen identified three main factors that influence customers' purchasing decisions, and published them in the January/February 2014 issue of the Harvard Business Review. These are:

Prior preferences, beliefs, and experiences (P).
Information from marketers, such as packaging, pricing, and advertising (M).
Input from other people, such as friends, family, and peers (O).

The more a person is influenced by one of these factors, the less influence the other factors will have. To make the most of people's preferences, you need to identify which factor is the most influential, and then tailor your marketing strategy to fit this.

Let's look at these factors in more detail:

Prior Preferences, Beliefs, and Experiences (P)

Routine, functional, and low-risk purchases are often influenced by prior preferences, beliefs, and experiences. For example, customers will often decide what type of milk, beverage, or detergent to buy, based upon past experience and personal preferences. They don't give the decision a great deal of thought, and they buy largely from habit.
