This piece is a companion to Marketing 1.0 to 7.0: from products to minds. The eras describe the strategic context; the Ps describe the day-to-day mechanics inside it. Together they cover most of what a working marketer thinks about day to day.
The first thing every marketing student learns is the 4 Ps: Product, Price, Place, Promotion. Memorise those 4 words and you’ve got the framework for the decisions a marketer makes most days: what to sell, how much to charge, where to make it available, and how to tell people about it.
The framework has had a long career. E. Jerome McCarthy introduced the 4 Ps in 1960, building on the “marketing mix” thinking of the 1940s and 50s, and Philip Kotler popularised them worldwide through Marketing Management, which is how they became the global teaching standard.
Marketing has expanded enormously since, and the Ps haven’t been left alone. There are now 5, 7, 8, 12, even arguments for 15. So the question most marketers eventually hit is: how many Ps does marketing really need? The honest answer is that it depends what you’re doing. Most days, the 4 originals still do most of the work. The rest are lenses you reach for when something specific demands closer attention.
Product
What you’re offering: the good or service itself, plus everything around it. Features, design, packaging, warranty, brand experience. Kotler describes a product as concentric layers: the core benefit, the tangible product around it, and the augmented layer of warranty, service and relationship. Most marketers work in those outer layers day to day.
Price
Costs, list pricing, discounts, bundles, payment terms. The strategic decision on top of all that is positioning: a premium price signals premium value; a low price signals accessibility or competitive aggression. Both are valid; what matters is alignment with the rest of the mix. If your unit economics don’t work at the price you’re charging, the rest of the mix won’t fix that.
Place
Distribution, channels, locations, fulfilment. Where can the customer find you, when, and how easily? In 1960 this was mostly retail logistics. Today it’s omnichannel reality: physical stores, e-commerce, marketplaces, social commerce, and branded experiences inside someone else’s platform. Trade marketing, shopper marketing, and logistics all live under this P.
Promotion
All the ways the brand communicates: advertising, public relations, social, content, email, SMS, search, influencers, events. The job is to inform, persuade, and build a relationship that outlasts any single campaign. This is the P most people think of first, partly because it’s the most visible.
Where the 4 Ps don’t reach
The 4 Ps are operational. They describe how you set the mix; they don’t set the strategy around them. That strategy covers 4 other things: which segment you’re going after, who else is trying to serve it, how you want to be remembered relative to them, and where the business is heading next.
The 4 Ps are what you adjust; the strategy around them is the field you’re playing on.
The service extension
The original 4 Ps work beautifully for goods. From the 1980s, service marketers noticed the framework didn’t quite cover their territory: a bank account isn’t something you put on a shelf, and a haircut isn’t a thing you can package. Booms and Bitner (1981) added 3 more: People (the staff delivering the service are part of the product), Process (the delivery steps are the experience), and Physical evidence (the environment as a clue to invisible quality). That gives the 7 Ps of service marketing, still the standard for service businesses.
The expanding alphabet
From the 2000s onwards, digital, social, AI, and regulation have each pulled new Ps into the conversation. The ones worth knowing: Personalisation (AI-enabled tailoring at scale, where restraint is the rule) and Permission (Seth Godin’s reframing of marketing as something done with the customer’s consent, now backed by GDPR and similar privacy law). Then Participation (customers as collaborators), Peer-to-peer (recommendations carrying more weight than advertising), and Planet (the expectation that brands take a position on environmental impact, with greenwashing carrying real cost).
There are more: Partners, Public relations, Positioning, Profit. Different authors propose different lists, most useful in the right context. None are universal; each catches something the original 4 don’t quite reach.
The trap of too many Ps
Once you start adding letters, it’s hard to stop. The cost is that it becomes easier to talk about marketing than to do it. Most companies struggling with their marketing are underweighted on the original 4. A great product, sensibly priced, made easily accessible, and clearly communicated: that’s a marketing operation. Adding 7 more lenses doesn’t help if you haven’t run the basic 4.
How many Ps, then?
As many as the work demands. For most marketers most days, 4. Service businesses use 7. Digital-native businesses reach for a few more once Personalisation, Permission, Participation, or Planet become material to the work.
Each P is a vantage point. A marketing strategy is the set of answers you give, organised into a coherent mix that fits the business and the audience. Not the longest list of Ps, but the clearest mix of the ones that matter.
That mix sits inside the wider evolution of marketing the discipline has worked through for a century. The Ps are the mechanics; the eras are the context they get applied within. Both together, plus a clear answer to who you’re for and why it matters, is most of what any marketer needs.
