The 5Ds of digital marketing: what each D covers, why its author later made it seven, and how to use them as a checklist

The 5Ds of digital marketing are digital devices, digital platforms, digital media, digital data and digital technology. Dave Chaffey created them as a simple memory aid for what a business has to manage in digital marketing, for the seventh edition of his textbook Digital Marketing: Strategy, Implementation and Practice. In a 2022 update he expanded the list to seven by adding digital goals and digital audiences at the front. Used as a checklist, the five original Ds stop digital marketing from shrinking to "our website" or "our Facebook page".

Where the 5Ds come from

Chaffey explains the origin on his own site in "What is digital marketing?" (updated 13 January 2022). He says he kept hearing narrow definitions inside businesses, such as "digital marketing is our website" or "digital marketing is our Facebook page", and that scope that narrow means digital never gets the budget to compete. The 5Ds went into the first chapter of the seventh edition to give students a basic picture of what is involved. Students already knew devices and platforms from their own lives, he notes, but not the management ideas of media, technology and data.

The book has moved on since. The ninth edition, written with Fiona Ellis-Chadwick and Majd AbedRabbo, was published in 2025. When you meet the 5Ds in a course or an interview question, the five below are the answer. When you plan, the seven-D version is the more complete one.

The five Ds, one at a time

The definitions below follow Chaffey's own wording, with a note on what each one asks a business to decide.

1. Digital devices

Chaffey's definition: audiences interact with businesses through a mix of smartphones, tablets, desktop computers, TVs, gaming devices, smart assistants and other connected devices that form the Internet of Things.

The decision it forces: which devices your customers actually use at each step. A takeaway gets ordered on a phone. A software contract gets read on a laptop. Design and test for the device where the decision happens.

2. Digital platforms

Most of those interactions happen through a browser or apps from the major platforms. Chaffey names Facebook (and Instagram), Google (and YouTube), Twitter, LinkedIn, Apple, Amazon and Microsoft.

The decision it forces: which few platforms to be present on properly. Each platform has its own rules, formats and ranking systems, so being everywhere thinly usually does less than being strong on two or three.

3. Digital media

The paid, owned and earned channels used to reach and engage people: advertising, email and messaging, search engines and social networks. Owned media also includes your website, apps and content strategy.

The decision it forces: the balance between paying for attention, building assets you own, and earning mentions from others. Chaffey adds that encouraging interactions on platforms through media matters most for increasing reach.

4. Digital data

The insight a business collects about its audience and their interactions with it, which, in Chaffey's words, now needs to be protected by law in most countries.

The decision it forces: what you collect, why, where it is stored, and the consent you hold for it. Measurement plans and privacy rules belong in the same conversation.

5. Digital technology

The marketing technology, or martech, a business uses to create interactive experiences, from websites and mobile apps to in-store kiosks and email campaigns.

The decision it forces: which tools you need to run the plan, and who owns each one. A CRM nobody updates is a cost, not a capability.

From five Ds to seven

For the eighth edition, Chaffey says reviewers wanted more on artificial intelligence and big data, and he wanted to fix a chapter structure he had never been happy with. The result was the 7Ds of managing digital marketing:

D	In the 5Ds?	What it covers
Digital goals	Added in 2022	What the business aims to achieve through digital, including new business models, always-on marketing and SMART campaign objectives
Digital audiences	Added in 2022	Online audience characteristics, behaviour and preferences, so content can be made relevant to each segment
Digital devices	Yes	Phones, tablets, computers, TVs, gaming devices, smart assistants and connected devices
Digital platforms	Yes	The major online services and their apps
Digital media	Yes	Paid, owned and earned channels
Digital data	Yes	Audience insight, protected by law
Digital technology	Yes	Martech for websites, apps, kiosks and email

The two additions answer the obvious gap in the original list: five Ds describe the tools and channels, but not what you want from them or who you are trying to reach. Starting with goals and audiences puts the plan before the tools.

Using the Ds as a checklist

The framework is most useful as a set of questions. Write one short answer to each before you choose a channel or buy a tool.

• Goals: What should digital deliver this year, in a number you can measure: enquiries, online sales, bookings?
• Audiences: Who buys, what do they search or ask before buying, and what puts them off?
• Devices: Where does the decision happen, on a phone in a hurry or on a laptop after research?
• Platforms: Which two or three platforms do those people use for this decision?
• Media: What will you pay for, what will you own, and what do you need others to say about you?
• Data: What will you track to know it is working, and what consent do you need?
• Technology: Which tools run it, and who is responsible for each?

Take a small accountancy practice as an illustration. The goal might be more new-client enquiries before the tax deadline. The audience is owners of small firms. The decision tends to start on a phone and finish on a laptop. The platforms are Google and LinkedIn. The media mix is owned pages that answer common tax questions, a Business Profile with reviews (earned), and perhaps search ads in the busy weeks (paid). The data is enquiries by source, and the technology is the website, a booking form and a CRM. One page of answers like that is already a plan. Our guide to where SEO fits in the whole marketing plan goes deeper on the media decision.

How the 5Ds relate to the Ps

The 4Ps and 7Ps describe the marketing mix: product, price, place and promotion, plus people, process and physical evidence for services. The Ds describe the digital environment that mix now runs in. They work together. A change in digital media mostly affects promotion, a new platform can open a new place to sell, and data shapes almost every P. For a worked version of the mix, see the 7 Ps of marketing with examples.

Questions about the 5Ds of digital marketing

What are the 5Ds of digital marketing?

Digital devices, digital platforms, digital media, digital data and digital technology. Dave Chaffey created them as a memory aid for what a business must manage in digital marketing.

Who created the 5Ds?

Dave Chaffey, for the seventh edition of Digital Marketing: Strategy, Implementation and Practice. He describes their origin on davechaffey.com.

Are the 5Ds still used?

Yes, in courses and exams especially. Chaffey himself moved to the 7Ds in 2022, adding digital goals and digital audiences, so use the seven for planning.

What is the most important D?

Chaffey singles out interactions on digital platforms through digital media as most important for increasing reach. In planning, goals come first, because they decide what the other Ds are for.

What is the difference between the 5Ds and the 4Ps?

The 4Ps are the marketing mix a business controls. The 5Ds describe the digital devices, platforms, media, data and technology through which that mix reaches customers.

The device on Chaffey's list that now answers back

Smart assistants sit in Chaffey's definition of digital devices. Since then, assistants such as ChatGPT, Gemini and Perplexity have become a place where people ask which supplier to use, and they answer with names. That cuts across three Ds at once: a new device habit, a new kind of platform, and a form of earned media you do not buy. Checking whether those answers include your business is a newer discipline than the 5Ds, and AI Knows Us works in it, measuring which assistants name a business and which sources they lean on.
