What is digital marketing? (Definition)

Digital marketing is any marketing that uses the internet or electronic devices to deliver a message and measure its effect. For example, it covers a Google search ad, an Instagram Reel, a blog post written to rank on Google and a series of personal emails.

At its core, digital marketing has three features:

• Digital delivery: first, content and ads reach people through websites, apps, search engines and social platforms instead of print.
• Data you can measure: also, every click, view and sale can be tracked as it happens, with tools such as Google Analytics or Meta Ads Manager.
• Two way contact: finally, people can comment, share and reply, so brands build relationships instead of just broadcasting.

In short, digital marketing is how a modern business gets found, gets trusted and gets chosen online. And the audience is huge. According to the Digital 2026 Global Overview Report by DataReportal, 6.04 billion people used the internet by October 2025. That is 73.2 percent of the world’s population. Moreover, the same report says people spend roughly 33 and a half hours a week with online media.

How digital marketing works

Digital marketing usually follows a customer through four stages, often called the marketing funnel:

1. Awareness: first, the customer finds your brand through search results, social media, video or paid ads.
2. Consideration: next, they research your product through articles, reviews and comparison pages.
3. Conversion: then they act. For instance, they buy, sign up or send an enquiry, often after a reminder ad, an email or a strong landing page.
4. Loyalty: finally, email, loyalty programs and personal content keep customers coming back.

So every channel below plays a part in one or more of these stages.

Digital marketing vs traditional marketing

These differences explain where ad money is going. For example, WARC Media’s forecast of October 2026 expects global ad spend to grow 11.9 percent to 1.34 trillion US dollars in 2026. In addition, social media, search and retail media together take 66.4 percent of that total.

10 types of digital marketing

1. Search engine optimization

Search engine optimization, often shortened to SEO, means improving a website so it ranks higher in the free results on Google and Bing. Today, it also covers AI answers, such as ChatGPT and Google AI Overviews. It includes four kinds of work:

• On page work: first, keywords, page titles, descriptions, headings and links between your own pages
• Technical work: also, site speed, mobile use, how easily Google reads the site and structured data
• Off page work: then links from other websites and mentions of your brand
• Answer engine work: finally, writing content so AI assistants can quote it directly

Marketers rate this channel highly. In fact, HubSpot’s marketing statistics, drawn from its State of Marketing Report 2026, show that websites, blogs and search engine optimization remain the top channel for return on investment. For a full plan, read our digital marketing strategy guide.

2. Content marketing

Content marketing means publishing useful blog posts, guides, videos and podcasts for a clear audience. As a result, it supports search rankings, builds trust and moves readers toward a purchase.

3. Social media marketing

Social media marketing means promoting a brand on Instagram, TikTok, LinkedIn, Facebook, X and YouTube. Right now, short video leads the way. In HubSpot’s 2026 research, 49 percent of marketers named short video as the format that brings the best return. To plan it, follow our social media marketing strategy guide.

4. Pay per click advertising

Pay per click advertising means paid ads on Google, Bing or social platforms, where you pay when someone clicks. Google Ads remains the main source of paid visits from people who are already searching. Similarly, social platforms sell sponsored posts, which our guide to the Instagram sponsored post explains step by step.

5. Email marketing

Email marketing means sending targeted messages to people who joined your list. Although it is one of the oldest digital channels, it still performs well. For example, Litmus, an email testing company, says email returns about 36 US dollars for every dollar spent.

6. Affiliate marketing

Affiliate marketing means paying partners a commission for each visit or sale they send you through their own links. So you pay only for results.

7. Influencer marketing

Influencer marketing means paying people with an engaged following to show your product in their own voice. It works well on Instagram, TikTok and YouTube, especially for younger audiences. On DeeGeet, brands can find and book vetted creators and see their prices first.

8. Marketing automation

Marketing automation means using software such as HubSpot, Klaviyo or ActiveCampaign to send the right message when a person takes an action. Also, AI is now part of daily marketing work. For instance, HubSpot’s State of Marketing Report 2026 found that 80 percent of marketers use AI to create content.

9. Video marketing

Video marketing covers promotional and teaching videos on YouTube, social platforms and websites. In Wyzowl’s 2026 video marketing survey, 91 percent of businesses said they use video in their marketing. Moreover, 82 percent of marketers said video gives them a good return.

10. Mobile marketing

Mobile marketing means marketing built for smartphones, such as text message campaigns, app alerts and ads made for small screens. Phones now carry most web visits. According to Statista, using StatCounter data, mobile devices produced 58.5 percent of global website traffic in 2025. Therefore, every page and ad must work well on a phone.

Why digital marketing matters: 2026 industry statistics

Here is what current data says about digital marketing:

• Internet users: 6.04 billion people, or 73.2 percent of the world, were online by October 2025 (DataReportal, Digital 2026).

So one thing is clear: digital marketing is now the main place where brands compete for attention, trust and sales.

Benefits of digital marketing

• Low cost: first, small businesses can compete with big brands on a fraction of a TV or print budget.
• Precise targeting: also, you can reach people by age, place, interests, device and even buying intent.
• Clear results: you can see which campaigns bring leads, sales and revenue.
• Reach at any hour: your website and content work day and night, across borders.
• More engagement: in addition, two way conversation builds a community around the brand.
• Fast fixes: weak campaigns can be paused or changed at once, unlike a printed ad.
• Credit where it is due: finally, tracking shows which channel led to each sale.

How to build a digital marketing strategy

A digital marketing strategy turns these channels into one plan. In brief, it follows five steps:

1. Set goals: first, decide what you want, such as awareness, leads, sales or repeat buyers. Then make each goal specific, measurable, realistic and tied to a date.
2. Know your audience: next, describe your ideal customers, their problems and how they behave online.
3. Review what you have: after that, check your website, search rankings, social accounts and content.
4. Choose your channels: then pick the channels your audience uses and your budget allows. For example, search and content build results over time, while paid ads work faster.
5. Plan, track and improve: finally, plan your content, set up tracking before you launch, test different versions and review results every month.
