KEY IDEAS
What you will learn
- Begin with a diagnosis
- Give every channel a job
- Measure a chain of outcomes
01
Start with a diagnosis
Describe the market before selecting tactics: customer jobs and barriers, available alternatives, category trends, company capabilities and constraints. Interviews reveal language and motives; observation reveals behaviour; surveys estimate patterns; transaction and search data show what people actually do. Each method has different biases.
Turn the diagnosis into a small number of choices. Which segment has a problem the organisation can solve credibly? What outcome matters to that segment? Why should it prefer this offer over the next-best alternative? A long list of channels cannot compensate for an unclear answer.
02
Build a coherent value proposition
The product, price, distribution and promotion should tell the same story. A premium position needs product evidence, service and availability that support a premium price. A convenience promise fails when checkout or delivery adds friction. Marketing communication works best when it expresses value already present in the offer.
Write one testable message hypothesis: for a defined audience, this benefit supported by this evidence should change this perception or behaviour. Creative executions can vary around that hypothesis while preserving recognizable brand assets and an accurate claim.
03
Assign channels a job
Different channels solve different communication problems. Search captures expressed demand; display and video can build or refresh awareness; email develops an existing permission-based relationship; public relations can add third-party reach; sales interaction handles complex objections. Channel selection should follow audience behaviour and objective rather than fashion.
Plan reach, frequency, sequence, budget and destination together. A persuasive ad leading to an irrelevant or slow landing page wastes attention. Integrated communication coordinates the promise across media while adapting length, interaction and evidence to each format.
04
Measure a chain, not one vanity number
Use a measurement ladder: delivery metrics such as reach and impressions; attention or interaction metrics such as viewability and qualified visits; intermediate outcomes such as recall, enquiries and trials; and business outcomes such as incremental contribution margin, retention and customer lifetime value. The closest metric is not always the most important.
Compare performance with a credible baseline. Randomized experiments are strongest when feasible; holdout groups, geographic tests and carefully designed before–after analyses can also improve inference. Report uncertainty, sample size and unintended effects. Optimisation should seek durable value, not merely the metric easiest for an algorithm to increase.
