Philip Kotler

Kotler's Marketing Management is the textbook that defined how marketing is taught in business schools worldwide. If you have been taught segmentation, targeting and positioning as a sequence, or the marketing mix as a framework rather than a list, that is largely his organising work.

His argument was that marketing is not advertising and not selling — it is the whole business decision about which customers to serve and what to offer them, of which promotion is one small part.

Why it matters to a small business

It is the antidote to treating marketing as the thing you do after the product exists. In his framing, marketing decides what the product is.

What they teach

Segmentation, targeting, positioning

The sequence that underpins nearly all marketing strategy: divide the market, choose who to serve, decide what you will mean to them. Skipping it is why most small-business marketing is generic.

Marketing is not promotion

Promotion is one of the four Ps. Treating marketing as the advertising budget guarantees you are competing on message rather than on offer.

Know the customer's alternatives

Value is relative. Kotler's framing of customer value as benefits against costs *compared with alternatives* is what makes it a usable idea rather than a slogan.

2. Kotler Marketing Group — The consultancy, with articles applying the frameworks.

Who it suits

Anyone who wants the structural version of marketing rather than a list of channels and tactics.

And who it does not

It is a textbook tradition — thorough, formal and long. For a one-person business the essentials are covered faster elsewhere.
