Simply put, our definition of digital marketing, or online marketing, is:
"Achieving marketing objectives through applying digital media, data and technology."
Within this broad digital marketing definition, there are many vital channels and platforms that we will introduce and share strategies and tactics for in this article, as well as the key digital marketing KPIs and metrics for success. To our overview of digital marketing relevant for 2025 we also share some of the latest insights on which the most successful digital marketing channels are in 2025.
In this overview of digital marketing designed for people who are new to it, I will cover:
To help explain the concepts I will illustrate this article with key visuals from my Digital Marketing: Strategy, Implementation and Practice book. If you're more interested in a strategic approach to digital marketing, see our article on: Digital marketing strategy: how to structure a digital marketing plan.
For businesses to compete effectively today, they must use digital marketing to support their business and marketing strategies. Each one of us now spends several hours each day using digital media, whether we’re looking for entertainment, social interaction or seeking new products.
Businesses and brands that don’t have the right digital tactics shown in the visual within their marketing communications programs miss out on opportunities to influence consumers at key online touchpoints.
Growth in the use of digital media and technology has led to new customer journeys or paths to purchase that are highly complex as purchase decisions are potentially influenced by many touchpoints which can be used by digital marketing.
Our customer lifecycle visual summarizes how the potential paid, owned, and earned digital media channels or communications tools offline may influence purchases across the customer lifecycle.
Note that TOFU, MOFU, MOFU refers to Top, middle and bottom-of-funnel content where content is used to support nurturing through the customer lifecycle.
This visual is aimed at helping businesses audit their use of digital marketing as part of a 'situation gap analysis' where they can review whether they are using, or are investing sufficiently, in the most appropriate 'always-on' digital communications to achieve their goals across the RACE planning framework created by Smart Insights.

It highlights some of the many internet and online marketing channels businesses can integrate to get the best results from digital marketing today. While some channels such as social media and SEO are well known, in our experience, we find that some potential always-on marketing techniques such as ad and email retargeting and influencer outreach shown in the visual are used less widely.
You can find out more in my 7-minute customer lifecycle marketing explainer video:
Later in this explainer, we'll show how you can simplify the management of digital marketing channels to six key channels that are relevant for every business from the smallest to the largest.
In my book, I simply define digital marketing as:
Achieving marketing objectives through applying digital media, data and technology.
This short definition helps remind us that it is the results delivered by technology that should determine investment in digital marketing, not the adoption of the technology! We also need to remember that despite the popularity of digital devices for product selection, entertainment, and work, we still spend a lot of time in the real world, so integration with traditional media remains important in many sectors.
In practice, digital marketing focuses on managing different forms of online company presence, such as company websites, mobile apps and social media company pages, integrated with different online communications techniques introduced later in this explainer. These include search engine marketing, content marketing, social media marketing, online advertising, email marketing and partnership arrangements with other websites.
For the past 15 years, Smart Insights has specialized in helping marketers learn a more structured, strategic, data-driven approach to digital marketing.
Online marketing can be considered to be equivalent to internet marketing and digital marketing. Most in the industry would look at it this way.
However, digital marketing is sometimes considered to have a broader scope than online marketing since it refers to digital media such as web, e-mail and wireless media, but also includes management of digital customer data and electronic customer relationship management systems (E-CRM systems).
It is useful to note that, despite digital using different communications techniques to traditional marketing, its end objectives are naturally no different from the objectives that marketing has always had. It can be easy to set digital objectives based around ‘vanity metrics’ such as the number of ‘likes’ or followers, so it is useful to bear in mind this definition of marketing advanced by the Chartered Institute of Marketing:
'Marketing is the management process responsible for identifying, anticipating and satisfying customer requirements profitably'.
This definition emphasizes the focus of marketing on the customer while at the same time implying a need to link to other business operations to achieve this profitability. Yet, it's a weak definition in relation to digital activity since it doesn't emphasize communications which are so important to digital activity.
In Digital Marketing Excellence, my co-author PR Smith and I note that digital marketing can be used to support these aims as follows:
Smart Insights members can access marketing strategy and planning tools and templates across 20 toolkits designed to improve marketing performance at each stage of the funnel.
Generative AI (GenAI) tools like ChatGPT and Google Gemini have proved an exciting addition to marketers' toolset. Although it's well known that many marketers are using AI to support copywriting, our research shows that many businesses are using these to support them when creating digital marketing strategies and plans too.
Since GenAI is a key part of modern marketing, we have created many new resources to help marketers tap into them:

There are many online communications techniques that marketers must prioritize to include as part of their communications strategy. Marketers often use paid, owned and earned media to describe investments at a high-level, but it’s more common to refer to six specific digital media channels when selecting specific always-on and campaign investments.
To simplify prioritization, we recommend considering the paid, owned and earned techniques available within six digital media channels or communications tools shown in the next visual. Combining the techniques in this way gives 18 digital communications techniques for businesses to consider. Companies with limited budget for paid media can focus on Owned and Earned techniques.
Through 2024 and 2025 the growing importance of Generative AI and increase in Zero-clicks caused by Google's AIO Overviews have caused many to question the importance of SEO, but the ongoing value of organic search is suggested by this recent research showing that organic search is the top media channel for large businesses and still accounts for over one quarter of all website visits. Of course, if you get it right, it can be higher still, for example, for Smart Insights it accounts for around 60% of all of our sessions.
This insight is taken from the 2025 Contentsquare Digital Experience Benchmarks which is a good quality source. Their report is based on website interactions for their 6,000 largest clients using their analytics solution based on a combined 90 billion sessions and 389 billion page views. Their customers are from a range of sectors including Retail, Financial Services, Telecom,Travel & Hospitality, B2B and Public Sector.

The six main digital channels available to any business and paid, owned and earned media options within these are:
Gaining visibility on a search engine to encourage click-through to a website when the user types a specific keyword phrase. Two key search marketing techniques are paid placements using pay-per-click via Google Ads or Bing, and placements in the natural or organic listings using search engine optimisation (SEO) where no charge is made for clicks from the search engine.
SEO can be considered owned media since it involves on-page optimisation by improving the relevance of content and technical improvements to the website to improve crawlability monitored through Google Search Console. SEO also has an Earned media component where visibility in the search engines can be improved by getting relevant ‘backlinks’ from websites which effectively count as a citation or vote.
This includes both paid advertising on social networks and organic social media amplification where companies aim to gain visibility through content shared by social media feeds and pages which are owned media. Earned social media is where a brand or social update is shared by a publisher or partner.
Social media marketing is an important category of digital marketing that involves encouraging customer communications on a company’s own site, or social presences such as Facebook or Twitter or in specialist publisher sites, blogs and forums. It can be applied as a traditional broadcast medium – for example, companies can use Facebook or Twitter to send messages to customers or partners who have opted in.
Use of online ad formats such as banners and videos on publisher sites to achieve brand awareness and encourage click-through to a target site. These are usually considered as separate investments from paid search and paid social ads since ads are typically displayed on publisher sites.
Programmatic display refers to where media and target audiences are selected by trading or bidding against other advertisers. Whereas native advertising involves paying to publish content that appears on a media site rather than a banner ad. It’s similar to when companies pay for features on pages in newspapers.
Display advertising is similar to sponsorship and in both cases, there may be a long-term relationship where a brand pays for its name to be associated with a publisher or event.
Involves maximizing favourable ‘offsite’ mentions of your company, brands, and products by other organizations and people, especially media sites or influencers such as celebrities.
Mentions may create name awareness, but have the benefit that they can also drive visits through links and support SEO through backlinks. These mentions may occur on publisher websites, blogs or social networks, and podcasts accessed by your target audience.
Guest-blogging involves writing an article for which no fee is typically charged on another business's website. It’s often a reciprocal arrangement.
Influencer outreach is used in both B2B and B2C communications. It usually refers to working with individuals rather than publishers to gain mentions through their social media, blogs or podcasts.
Digital PR also includes responding to negative or positive online brand mentions and conducting public relations via a site through a social media news centre or blog, for example.
Creating and managing long-term arrangements to promote your online services on third-party websites or through website content and messaging. Affiliate marketing involves a commission-based arrangement where the advertiser only pays when a sale occurs. It’s most applicable to the retail, travel, and financial services sector where an affiliate website will get paid for traffic when an online sale occurs.
Co-branding is a paid or owned media technique where two brands are featured within email marketing or native advertising. Co-marketing is similar, but it is a ‘contra’ arrangement for which no fee is usually paid when companies collaborate to share content with the aim of raising awareness and leads amongst the pooled audiences.
For example, we set up a co-marketing arrangement for publisher Smart Insights with martech vendor HubSpot where joint research reports were created to raise awareness and generate leads for both brands. HubSpot has dedicated co-marketing managers in different regions to manage this activity since they see it as important.
See their post The Who, What, Why, & How of Digital Marketing if you're not familiar with them.
Traditionally digital messaging to individuals who have subscribed to updates has focused on Email marketing, which is still a commonly used digital media channel since it is cost-effective. However, email is used less by younger audiences who are more likely to subscribe to mobile push notifications from websites and apps.
Digital messaging options include placing ads in third-party e-newsletters (paid media) or most commonly the use of an in-house list for customer activation and retention (owned media) or co-marketing techniques using other companies newsletters. Buying or renting lists of email addresses is considered as a spamming technique and not permitted under the privacy legislation described.
Success in digital marketing requires you to choose a good set of digital marketing goals covering a range of different measures to help set, review and control a successful performance and reap the benefits across all digital marketing activities.
We recommend you consider these 5S goals and specific SMART objectives to ensure your digital marketing investments give you the returns you need. The 5Ss of digital marketing were devised by PR Smith and are explained in our Digital Marketing Excellence book.
You can learn more about them in our article on setting goals for your digital marketing.

In this section, we introduce five differentiated 'types' of digital communications that generate significant opportunities for digital marketers to reach, interact with, convert, and engage their audiences online.
These five fundamental digital marketing concepts are built into nearly all types of digital marketing strategies and are regularly discussed and reviewed by marketers as part of their digital marketing activities. If you work in digital marketing, these are the techniques that you will use to underpin your marketing.
Although these five types of digital marketing comms are more readily achieved online compared to traditional media, we find that offline communications such as TV ads can also integrate well with these:
Amongst marketing professionals, the digital media interactions shown in the first picture is a powerful new approach to marketing, now commonly known as inbound marketing, a term also promoted by HubSpot. Inbound marketing can be defined as when the consumer is proactive in seeking out information for their needs, and interactions with brands are attracted through content, search and social media and internet marketing.
Inbound marketing is powerful since there are lower-cost organic options for which there is no media cost including organic social media and search engine optimisation. Advertising wastage is reduced since we can target specific individuals when they are looking for products, they are proactive and self-selecting. But this is a weakness since marketers may have less control than in traditional communications where the message is pushed out to a defined audience and can help generate awareness and demand.
Traditional media are predominantly push media where the marketing message is broadcast from company to customer, although interaction can be encouraged through direct response to phone, website or social media page. However, online, it is often the customer who initiates contact and is seeking information through researching information on a website. In other words, it is a ‘pull’ mechanism where it is particularly important to have good visibility in search engines when customers are entering search terms relevant to a company’s products or services.
Permission marketing is closely related to inbound marketing. It is an established approach to online marketing that is still highly relevant today as a practical foundation for generating online leads and audience engagement. ‘Permission marketing’ was a term first coined by marketing gurn Seth Godin way back in 1999. This classic value exchange is based on information or entertainment – a B2B site can offer a free report in exchange for a customer sharing their email address, while a B2C site can offer a newsletter with valuable content and offers. Many retail sites today still feature an option to subscribe to a newsletter with a discount for first-time purchasers since this is a practical method to gain potential customers.
Permission marketing is a modern take on Customer relationship management (CRM), this is using digital communications technologies to maximise sales to existing customers and encourage continued usage of online services through techniques including a database, personalised web messaging, customer services, chatbots, email and social media marketing.
Success in permission marketing requires exceptional, compelling content. To emphasize the importance of content marketing to gaining permission, encouraging sharing and ongoing engagement through websites and social media, the concepts of content marketing and content strategy have developed to describe best-practice approaches to engaging audiences and achieving business outcomes through content. Previously content was limited by the cost of printing and distributing brochures or direct mail, but these are no longer barriers, giving many more opportunities to engage audiences online through content in a rich variety of formats including web pages, downloadable guides, blog posts, social posts, videos, podcasts and interactive product selectors and quizzes.
Content marketing is defined as:
The management of text, rich media, audio and video content aimed at engaging customers and prospects to meet business goals published through print and digital media including web and mobile platforms which is repurposed and syndicated to different forms of web presence such as publisher sites, blogs, social media and comparison sites.
You can see the challenge content strategy presents, since today there are so many different types of content delivered in different forms to different places on different access platforms, yet it is increasingly important to engage customers in digital media. Investment in managing content ideation, creation and distribution is needed to assess and define:
To be successful in content marketing we recommend that websites create a Content marketing hub which is a central branded location where your audience can access and interact with all your key content marketing assets. In a practical sense, the content hub can be a blog or new section, an online customer magazine or a resource centre.
In traditional ‘push’ media, there were few options for brands to interact with audiences directly. Digital media offers many more options for direct-to-customer (D2C communications), but with the challenge of gaining ‘cut-through’ given the amount of content. We define customer engagement as:
Repeated interactions through the customer lifecycle prompted by online and offline communications aimed at strengthening the long-term emotional, psychological and physical investment a customer has with a brand.
This difficulty in gaining and keeping the attention of audiences across today’s fragmented media landscape has led to the emergence of the concept of customer engagement as a key challenge with which digital marketers are increasingly concerned.
We need to be careful to precisely define engagement since the term is often used loosely to describe short-term audience engagement with a single communication, such as when a prospect engages with a single landing page, email or social media update. While this short-term interaction is important to boost response from these communications, what is arguably more important to business success today, and far more challenging, is long-term engagement through time with our prospects, customers and subscribers.
We define customer engagement as Repeated interactions through the customer lifecycle prompted by online and offline communications aimed at strengthening the long-term emotional, psychological and physical investment a customer has with a brand.
To be successful in marketing communications today requires marketers to develop a deep understanding of digital audiences, which includes the insights on customer characteristics and behaviour we cover under the section on ‘Digital data’. Developing good customer insights to understand your audiences and then target them with more relevant communications and offers has always been a fundamental of marketing as we saw from the definition of marketing in the previous section.
In the pre-digital era, marketing activities were planned in campaign ‘bursts’ around new product launches and promotions. To be effective, digital marketing needs a change in mindset so businesses invest sufficient time and budget into defining and optimizing what is known as ‘always-on lifecycle marketing’ activities which can be used in an integrated way to maximize visibility and conversion through the customer lifecycle.
Always-on lifecycle marketing is a planned approach to scheduling and optimising continuous marketing activities which support customer acquisition and retention. These activities aim to maximize visibility and persuasion through the customer lifecycle for all the activities like those shown in the first visual.
Our research, explained in our post 10 reasons you need a digital marketing strategy report found that nearly half of companies don’t have a clearly defined digital marketing strategy. But of those who do, the majority have integrated it into the marketing strategy. Currently, about 12% are still using a separate digital strategy document, which is the first step in the process toward a fully integrated strategy.
Many businesses make the mistake of only considering digital marketing strategy for the investment in the digital media channels we have covered. However, savvy businesses realize there are bigger opportunities from digital marketing such as reviewing new online business and revenue models.
To effectively use digital marketing many established, larger businesses have adopted digital transformation programmes. Analyst Brian Solis of Brian Solis of Altimeter defines digital transformation as :
“The evolving pursuit of innovative and agile business and operational models — fuelled by evolving technologies, processes, analytics, and talent — to create new value and experiences for customers, employees, and stakeholders”.
We define digital transformation as: A staged programme of organizational improvements to business models, People, Process and Technologies used for integrated digital marketing in order to maximize the potential business contribution of digital technology, data and media.
As part of defining the scope of opportunity when using a strategic approach to digital marketing, it’s helpful to think about which digital audience interactions we need to understand and manage through marketing communications. Digital marketing today is about managing many more types of audience interaction than simply a company website or email marketing. It involves harnessing all of these other ‘7Ds of managing digital marketing interactions’ which are shown in the visual below
The marketing activities that relate to the 7Ds that should be reviewed as part of a strategic approach to digital marketing are:

We have put together this new visual definition summarizing all the digital activities that need to be managed across the Smart Insights RACE Framework. It's used in the new, 6th edition of Dave's digital marketing book. The infographic is divided into activities to develop and manage digital strategy at the top through to the marketing activities at the bottom.
So, digital marketing is about utilizing digital technology to achieve marketing objectives. There is no essential need for digital to always be separate from the marketing department as a whole, as the objectives of both are the same. However, for now, it remains a useful term because digital requires specialist skills to utilize digital technology effectively.
