Changing Behaviour: The Real Job of Marketing

At its core, marketing is about one thing: changing behaviour.

Every campaign, advert, and promotion ultimately tries to persuade someone to do something. Most often that “something” is to buy a product or service. But the first purchase is only the beginning. The real success comes when customers return and buy again, turning a one-off action into a habit.

But changing behaviour isn’t easy.

Behaviour Change Starts with Real Needs

Persuasion only works when there is an underlying motivation. Trying to convince people to buy something they believe they don’t need or won’t benefit from is almost impossible.

This means marketers must begin with a deep understanding of their audience:

• What problems are customers trying to solve?

• How do these needs differ between customer groups?

• How are those needs currently being met?

• Where are the gaps or frustrations?

• Why might our product be a better solution?

Only when these questions are answered can marketing begin to influence behaviour effectively.

Make the Change Easy

Even when customers recognise a need, behaviour rarely changes overnight.

People are creatures of habit. Existing behaviours are comfortable and familiar. If marketers want to shift those behaviours, they must make the transition as easy as possible.

Often this means encouraging change through small, manageable steps rather than dramatic shifts. Gradual progress is far more achievable than expecting customers to transform their behaviour instantly.

The Power of Triggers

Understanding motivation and reducing friction is only part of the story. Behaviour change also requires a trigger — something that prompts action in the moment.

Triggers can take many forms:

• A promise of satisfaction or enjoyment

• The convenience of an easier solution

• Financial incentives such as saving money

• The appeal of greater efficiency or performance

The trigger reminds customers that the solution exists and encourages them to act.

The Fogg Behaviour Model

These ideas are captured in the Fogg Behavior Model, developed by BJ Fogg, founder of the Behavior Design Lab at Stanford University.

Fogg’s framework proposes that behaviour happens when three elements occur at the same time:

• Motivation – the person wants to do it

• Ability – the behaviour is easy enough to perform

• Prompt – something triggers the action

If any one of these elements is missing, the behaviour simply won’t occur.

Fogg’s research has influenced many fields, from health behaviour change to user-experience design. His work has even helped inspire the design thinking behind platforms such as Instagram.

One particularly important insight from his work is that emotion plays a key role in habit formation. Lasting behavioural change often happens when people feel something — delight, curiosity, satisfaction — not just when they repeat an action mechanically.

The Habit Loop

A similar perspective is offered by Nir Eyal in his book Hooked: How to Build Habit-Forming Products.

Eyal describes a four-stage cycle that encourages repeated behaviour:

1. Trigger – a cue prompts the user to act

2. Action – the user performs a simple behaviour

3. Reward – the user receives some form of payoff

4. Investment – the user contributes time, effort, or data

This investment increases the likelihood that the behaviour will be repeated in the future, gradually turning the action into a habit.

Behaviour Design in Practice

For marketers, behavioural frameworks are only valuable if they translate into practical action.

Typically the process begins with a message to the target audience — perhaps announcing a new product, a price reduction, or improved availability.

Once interest has been triggered, the next step is crucial: make the behaviour

incredibly easy.

Some of the most successful companies have built their products around this principle:

• Amazon simplifies purchasing with one-click ordering

• Netflix keeps viewers engaged with automatic playback of the next episode

• Spotify allows instant listening with a single tap

Each of these designs removes friction and encourages the behaviour to repeat.

Marketing as Behaviour Design

Seen this way, marketing is not simply about communication. It is about designing environments that make desired behaviours more likely.

The most effective marketers understand that persuasion depends on three things:

• real customer needs

• simple, low-friction actions

• timely prompts that trigger behaviour

When these elements come together, behaviour changes — and when behaviour changes consistently, habits form.

And that is when marketing really starts to work.
