The marketing mix: the 4Ps, the 7Ps and a template to fill in

The marketing mix is the set of variables a business controls when it takes something to market. The classic four are Product, Price, Place and Promotion: what you sell, what you charge, where it is available, and how people hear about it. Neil Borden popularised the idea of a marketing mix, and E. Jerome McCarthy organised it into the four Ps in his 1960 textbook Basic Marketing. Booms and Bitner added People, Process and Physical evidence in 1981 to cover services, giving the seven Ps. The model earns its keep as a consistency check: every P has to tell the same story, and a mismatch between any two of them is where money leaks.

The four, and the decisions inside each

P	The question	The decisions
Product	What problem does this solve, and for whom	Features, quality level, range, variants, packaging, naming, warranty, support, what you deliberately leave out
Price	What do we charge, and what does the number signal	List price, structure such as subscription or one off, discounts, payment terms, bundles, price for each segment
Place	Where can a buyer get it	Direct or through partners, retail, online, marketplaces, geographic coverage, stock and availability, delivery
Promotion	How do people learn about it and decide	Message, channels, advertising, sales effort, public relations, promotions, the proof you show

The three extra Ps for services

• People. In a service, the staff are the product. Hiring, training, scripts and how much authority a front line person has are mix decisions.
• Process. How the service is delivered: booking, waiting, handovers, what the customer has to do. Most service complaints are process complaints.
• Physical evidence. The tangible signals of an intangible promise: premises, uniforms, documents, the app, the invoice, the follow up call.

A template to fill in

SEGMENT: who this mix is for
---------------------------------------------
PRODUCT    What it is, who for, what we exclude
           Proof that it does the job
PRICE      Number, structure, discount policy
           What the price signals about us
PLACE      Routes to buy, coverage, availability
           Where our buyers already look
PROMOTION  One message, three proofs
           Channels, and the first objection answered
---------- services only ----------
PEOPLE     Who the customer meets, and their authority
PROCESS    The steps from enquiry to delivered
EVIDENCE   What the customer can see and keep
---------------------------------------------
CONSISTENCY CHECK
Does any P contradict another? Write the clash here.

A worked walkthrough

Take a physiotherapy clinic deciding to focus on post operative rehabilitation for knee and hip replacements. The example is illustrative, and the value is in how the Ps lock together.

• Product: a twelve week structured programme with a written plan, progress measurement at fixed points and discharge advice, rather than open ended appointments.
• Price: priced as the programme, not per session, which signals a course of treatment and makes the value legible against a hospital's own aftercare.
• Place: one clinic near the hospitals that perform the surgery, with early morning slots for people who are still working, and referral arrangements with the surgeons.
• Promotion: a page per procedure written in the words patients use, a named physiotherapist with the relevant qualification, patient stories where consent and the regulator allow, and the surgeons as the primary referral channel.
• People: clinicians trained in the same protocol, so the programme is consistent whoever delivers it.
• Process: a call within one working day of referral, the first appointment inside a week, progress notes shared back to the surgeon.
• Evidence: the printed plan, the measurement chart, the discharge letter.

The consistency check is the point of the exercise. A programme price alongside drop in sessions, or a premium programme promoted entirely through discount vouchers, would break the story the other Ps are telling.

Where the model needs help

The four Ps were written for products sold through channels, so two adjustments are worth making. Robert Lauterborn's 4Cs, proposed in 1990, restates the same decisions from the customer's side as customer value, cost, convenience and communication, which is a useful rewrite when a team starts talking only about itself. And in subscription and software businesses, Place is mostly about distribution and integration rather than shelves, while Product includes the onboarding experience that decides whether anyone keeps paying.

How to actually use it

1. Fill the template for each major segment separately. One mix for everybody is the most common misuse of the model.
2. Write the current state before the desired state, honestly, so the gaps show.
3. Run the consistency check and write down every clash.
4. Pick one P to change this quarter. Changing all four at once makes the result unreadable.
5. Revisit quarterly, and keep the old versions.

This page covers the marketing mix as a planning and audit tool. For the choices that sit above it, which segments and what position, strategic marketing covers that ground, and a marketing plan turns both into budgets and dates.

Asked and answered: marketing mix

What are the 4Ps of marketing?

Product, Price, Place and Promotion: what you sell, what you charge for it, where people can get it, and how they come to know about it. They were organised into that form by E. Jerome McCarthy in 1960.

What is the difference between the 4Ps and the 7Ps?

The 7Ps add People, Process and Physical evidence to cover services, where delivery and the people delivering it are part of what the customer buys. Booms and Bitner proposed the extension in 1981.

Is the marketing mix still relevant?

It remains the clearest checklist of what a business actually controls, which is why it survives in planning. Its strength now is the consistency test rather than the list itself.

How do the 4Ps relate to the 4Cs?

The 4Cs restate the same decisions from the buyer's point of view: customer value for product, cost for price, convenience for place, and communication for promotion. Use them when a plan starts reading as internally focused.

Which P should you change first?

Whichever one contradicts the others. If the consistency check finds no clash, price is usually the fastest lever and the one with the quickest readable result.

A fifth place your mix is being read

Promotion assumed a buyer who encounters your message or looks you up. A growing share now asks an assistant and takes the answer. ChatGPT, Gemini, Perplexity, Claude and Google's AI Overviews each name a few companies when asked who to use, and each answers differently and cites different sources, with no shared ranking between them.

What they summarise is your mix as other people have described it: your product, your price if it is published, where you are available, and what reviewers say. That makes a clear pricing page and accurate third party listings part of promotion in a new way. Ask the buying question a customer would ask in two or three assistants, keep your own name out of the prompt so the answer comes back clean, and compare what comes back with the mix you wrote. AI Knows Us tracks what those answers say about a business.
