What Is Digital Marketing? Definition, Channels, and Examples

Digital marketing is the promotion of a product, service, or brand through online channels: search engines, websites, social media, email, digital ads, and third-party sites such as publications, review platforms, and creators. It matters because it reaches buyers where they research before they buy, and because nearly every action is measurable, so you can see which efforts produce customers and shift budget accordingly.

What is digital marketing?

Digital marketing is any marketing activity that uses the internet or digital devices to reach, persuade, and keep customers. It covers the channels you own (your website, email list, and social profiles), the channels you pay for (search and social ads), and the channels you earn (press coverage, reviews, creator recommendations, and word of mouth online).

The term covers both the strategy (who you target and why) and the day-to-day execution (the ads, posts, emails, and pages themselves). A dental group’s marketing lead optimizing location pages, a founder posting on LinkedIn, and a skincare brand briefing a creator are all doing digital marketing.

How is digital marketing different from traditional marketing?

Digital marketing differs from traditional marketing mainly in targeting, measurement, and speed. The table below summarizes the differences.

Factor	Digital marketing	Traditional marketing
Channels	Search, social, email, websites, digital ads, online press	TV, radio, print, billboards, direct mail
Targeting	By search intent, interests, location, behavior	By broad audience of a station, publication, or area
Measurement	Clicks, conversions, and revenue tracked per campaign	Mostly estimated reach and indirect lift
Speed to adjust	Changes can go live the same day	Changes require new production and buys
Minimum budget	Can start small and scale	Often requires larger upfront commitments
Interaction	Two-way: comments, replies, reviews	Mostly one-way broadcast

Traditional channels still work, especially for broad local awareness. But many buyers now check a company online before they call, visit, or buy, so even offline campaigns tend to end in a search.

What are the main types of digital marketing?

The main types of digital marketing are SEO, paid advertising, content marketing, social media marketing, email marketing, influencer marketing, and affiliate marketing, with digital PR and AI search optimization increasingly treated as their own disciplines. Each type is covered in depth in our guide to the types of digital marketing strategies.

• Search engine optimization (SEO): improving your website so it ranks in search results for the queries your buyers use.
• Paid search and paid social (PPC, SEM): ads you pay for per click or per impression, on search engines and social platforms.
• Content marketing: articles, guides, videos, and tools that answer buyers’ questions and build trust.
• Social media marketing: building an audience and community on platforms such as LinkedIn, Instagram, and TikTok.
• Email marketing: messages to people who opted in, used to nurture leads and drive repeat purchases.
• Influencer and affiliate marketing: partnering with creators and publishers who recommend you to their audiences.
• Digital PR and earned media: coverage in publications, podcasts, and third-party sites. Our explainer on what earned media is covers why it carries more credibility than paid placement.
• Generative engine optimization (GEO): structuring your content and third-party presence so AI tools cite your brand in their answers. See our glossary entry on GEO.

How does digital marketing work?

Digital marketing works by moving a person through four stages: attract, capture, nurture, and convert. Each stage uses different channels and needs different metrics.

1. Attract. Get in front of the right people. SEO and content catch people who are searching; paid ads and social reach people who are not yet searching; press coverage and creators put you in front of audiences who trust someone else’s recommendation.
2. Capture. Turn anonymous attention into something you can follow up on: an email signup, a booked call, a quote request, an account, or a first order. This happens on focused landing pages with a clear offer and a short form, not on a generic homepage.
3. Nurture. Build the relationship until the person is ready to buy. Email sequences, retargeting, useful content, and consistent social presence keep you in mind. Tools such as a CRM and an email platform track where each lead stands.
4. Convert. Make the decision easy: a clear call to action, visible proof (reviews, case studies, press), and a checkout or booking process with as few steps as possible.

A local health clinic, for example, might rank for “urgent care near me” (attract), offer online booking on a location page (capture), send appointment reminders and follow-up care tips (nurture), and ask for a review after the visit, which helps attract the next patient. A clothing retailer might run paid social ads to a new collection page, capture emails with a first-order discount, send style content and personalized offers, and convert through a simple checkout.

Throughout, respect the people you are marketing to. Use opt-in lists only, be transparent about how you use data, and make unsubscribing easy. Trust is the asset that makes every stage cheaper.

How do you measure digital marketing?

You measure digital marketing by tracking key performance indicators (KPIs) for each stage and connecting them to revenue. Useful KPIs include:

• Attract: traffic by source, search rankings, impressions, share of voice in press and AI answers.
• Capture: conversion rate on landing pages, cost per lead.
• Nurture: email open and click rates, lead-to-opportunity rate.
• Convert: sales, cost per acquisition, average order value, customer lifetime value.

An analytics platform such as Google Analytics shows where visitors come from and what they do. The key is attribution: knowing which campaign or channel deserves credit for a sale. No model is perfect, especially for brand and press work that influences buyers well before they click, but measuring consistently lets you compare channels and move budget toward what works.

How does digital marketing work across countries and languages?

Marketing to multiple countries requires localization, not just translation. That means adapting messaging to local culture and buying habits, researching which search engines, social platforms, and marketplaces each market actually uses, and handling technical details such as language-specific pages and hreflang tags so search engines show the right version to the right visitor. Pricing, payment methods, and privacy rules also vary by region, so check them before launching paid campaigns abroad.

What does digital marketing mean for founders, local operators, and D2C brands?

Digital marketing looks different depending on your business model and how your buyers decide.

Seed to Series B founders. Your first job is credibility. Investors, candidates, and early customers search your name and your company before they take a meeting, and they increasingly ask AI assistants about your category. Press coverage, a consistent founder voice on LinkedIn and podcasts, and a clear website give both humans and AI tools something trustworthy to find.

Multi-location local operators. For an HVAC company, dental group, or salon brand with 3 to 15 locations, digital marketing is mostly local: a complete Google Business Profile per location, location-specific pages, a steady stream of reviews, and regional press. The goal is appearing in the Map Pack and AI Overviews for “near me” searches, and the KPI is calls and bookings.

D2C consumer brands. Discovery runs through other people’s voices. Editorial coverage in outlets like Allure, The Strategist, or Apartment Therapy, plus Tier-2 creators with 10K to 500K followers, drives first purchases, and email and retention flows drive the second and third.

What should you do next?

Pick one business goal for the next quarter and map it to the four stages: where you will attract attention, how you will capture it, how you will nurture it, and what the conversion step is. Then work through the steps in a digital marketing strategy to turn that map into a plan. If search and AI visibility are your weakest stage, our digital marketing, GEO, and SEO team can help.

Frequently asked questions

What is digital marketing in simple words?

Digital marketing is promoting a business online. It includes showing up in search results, posting on social media, sending emails, running online ads, getting featured in publications, and working with creators.

What are the 4 main stages of digital marketing?

The four main stages of digital marketing are attract, capture, nurture, and convert. You attract attention through search, social, ads, and press; capture it with a signup, booking, or first order; nurture the relationship with email and useful content; and convert with a clear offer and a simple purchase process. Satisfied customers then leave reviews that attract new buyers.

Is SEO part of digital marketing?

Yes, SEO is one of the core parts of digital marketing. It covers improving your website’s content, technical setup, and reputation with other sites so it ranks for the searches your buyers make. SEO now also overlaps with generative engine optimization, which aims to get your brand cited in AI-generated answers from tools like ChatGPT and Google AI Overviews.

How much does digital marketing cost?

Digital marketing costs vary widely because you can start small and scale. Organic work like SEO, content, and social mostly costs time or agency fees, while paid ads cost whatever budget you set. Agency fees depend on scope and channels. GetDigitize monthly retainers, for example, start at $3,500 per month.

Is digital marketing better than traditional marketing?

Digital marketing is usually better for targeting and measurement, while traditional marketing can still work well for broad local awareness. Digital channels let you reach specific audiences, test messages quickly, and track results to the sale. Many businesses combine both, using traditional media for reach and digital channels to capture and convert the searches that reach creates.
