Marketing principles

The ideas every integrated plan rests on, from the people who framed them: Kotler, Drucker, Levitt, Aaker, Keller, Ries and Trout, Porter and Sharp, in plain words and with their sources.

  1. The marketing concept: what marketing is for

    Drucker's purpose of a business, Levitt's marketing myopia, Kotler's needs, wants and demands, and how the marketing concept differs from the production and selling concepts, with what it changes for integrated communications.

    In short
    • A business exists to create and serve customers; marketing is the discipline that keeps the whole company looking at the market from the customer's side.
    • The selling concept starts from what the factory makes; the marketing concept starts from what the customer needs, and treats communication as one of four jobs, not the whole job.
    • For integrated communications this means briefing from the customer's need and decision, promising only what the product can deliver, and judging work by what customers did, not by what a channel delivered.
  2. Segmentation, targeting and positioning: choosing whom to serve

    Where segmentation came from, how the STP process works step by step, how to evaluate segments and choose a targeting strategy, the evidence-based debate over targeting versus reach, and how a position becomes the message house.

    In short
    • Segment to make a decision, not to describe a market: a segment is useful only if it is measurable, reachable, large enough, different in how it responds, and something you can act on.
    • The targeting debate is narrower than it looks: Ehrenberg-Bass argues for reaching all category buyers and catering only for differences that matter; Ritson argues for targeted activation alongside broad brand building. Both reject narrow targeting of brand communications.
    • STP ends in a position, and the position becomes the roof of the message house: one frame of reference, the parity points that qualify you and the difference that wins.
  3. The marketing mix: why price, product and place also communicate

    Borden's mixer of ingredients, McCarthy's four Ps, Booms and Bitner's seven Ps for services and Lauterborn's four Cs, where communications sits in the mix, and a practical check that the other Ps say what the campaign says.

    In short
    • The mix is a set of decisions made together: Borden's twelve ingredients, McCarthy's four Ps, seven for services. The number matters less than the fact that they are decided as one.
    • Promotion is the only P whose job is to speak, but every P sends a message: price signals quality, place signals who the brand is for, and in services the people and the setting are the proof.
    • Integration fails when the other Ps contradict the campaign. Check the mix against the message house before launch, and give one owner the authority to fix a contradiction.
  4. Positioning: the place a brand holds in the mind, and how to write it down

    Ries and Trout's positioning, Keller's frame of reference, points of parity and points of difference, the Ehrenberg-Bass challenge on differentiation, how to write a positioning statement, when to reposition, and how a position becomes the roof of the message house.

    In short
    • A position has three parts: the frame of reference that tells people what you are, the points of parity that make you a legitimate choice, and a point of difference that matters to the buyer.
    • Evidence that buyers see little difference between competing brands does not make positioning useless; it means the difference must be simple, consistently expressed and attached to assets people recognise.
    • Write the position as one statement, test it with the people who own the product, price and service, and make it the roof of the message house. Reposition only when the frame or the difference has really changed.
  5. Brand equity: what a brand is worth, and how communication builds it

    Brand equity is the value a brand adds beyond the product itself. Aaker treats it as a set of assets, Keller as the difference brand knowledge makes to how customers respond; both tell a marketer what to build, how to measure it and how integrated communication adds to it.

    In short
    • Brand equity lives in customers' memories before it shows up in prices and valuations: awareness, the associations people hold, perceived quality and loyalty are the levers.
    • Measure it on three levels: what customers think (tracking), what they do (penetration, price premium, price sensitivity) and what it is worth (a valuation that follows ISO 10668).
    • Integrated communication builds equity by repeating the same few associations and distinctive assets at every touchpoint, over years, and by keeping the experience true to the promise.
  6. How brands grow: the Ehrenberg-Bass laws, and the debate around them

    Decades of buying data show regular patterns: small brands have fewer buyers who are also slightly less loyal, and brands share buyers in line with their size. What that means for reach, consistency and the media plan, and where Binet and Field, Ritson and others disagree.

    In short
    • Growth comes mainly from more buyers, not from more loyalty: double jeopardy means loyalty largely follows market share.
    • Build mental availability (being thought of in buying situations, through category entry points and distinctive assets) and physical availability (being easy to buy).
    • Treat the laws as the default, then argue the exceptions: targeting, emotion and differentiation are still debated, and the best plans use broad reach and sharp creative together.
  7. Customer value and lifetime value: what a customer is worth, and what loyalty really buys

    Customers stay when the value they get beats the alternatives, and a customer's lifetime value is the discounted margin they will bring. How to estimate it, what the retention evidence does and does not show, and how to use NPS without being misled by it.

    In short
    • Lifetime value is margin, retention and time, discounted: estimate it per segment and compare it with what it costs to acquire a customer, never in isolation.
    • Retention matters, but the famous figures come from illustrative arithmetic and double jeopardy caps loyalty: a growth plan still needs new buyers.
    • Use NPS as a diagnostic with the reasons behind the score, not as the one number that predicts growth: the independent tests did not confirm that claim.
  8. Marketing strategy and growth: the frameworks to use with the board, and what they change in the brief

    Ansoff's growth matrix, Porter's generic strategies, the BCG growth-share matrix, jobs to be done and Kotler's Marketing 5.0 each answer a different board question. What each one says, where it falls short, and how the choice changes the communications brief.

    In short
    • Each framework answers one question: Ansoff where to grow, Porter how to win, BCG what role each business plays, jobs to be done why customers buy, Marketing 5.0 how technology should serve them.
    • The growth path changes the brief: penetration needs reach among category buyers, market development needs a new audience's language, product development needs launch support, diversification needs a brand decision first.
    • Bring the board numbers it already uses (penetration, price premium, customer value) and show how the communication plan moves them.
