Digital marketing, explained properly.
What digital marketing is, the nine types that matter, how to plan a strategy, what it costs in India and how to measure it — in one page, written by the team that does it every day.
What is digital marketing?
Digital marketing is the promotion of a brand, product or service through internet-connected channels — search engines, social media, websites, email, messaging apps and AI assistants — to reach people, persuade them and turn them into customers.
Its defining advantage over traditional marketing (TV, print, hoardings) is measurement: every impression, click, lead and sale can be tracked, so budget can move to what works within days instead of quarters.
The 9 types of digital marketing
Search engine optimisation (SEO)
Earning unpaid visits from Google by making pages that answer searches better than competitors. Slow to start, cheapest over time.

Learn more →Email & WhatsApp marketing
Owned channels that turn one-time buyers into repeat buyers — usually the highest-ROI channel in India.
Learn more →Influencer & UGC marketing
Borrowing the credibility of creators and real customers instead of brand-voiced ads.
Learn more →Website & ecommerce development
The store or site every other channel sends traffic to. A slow or confusing site wastes every rupee above it.

India has more than 900 million internet users, most of them on mobile, and the majority discover brands through Google, YouTube, Instagram and WhatsApp before they ever visit a store. A business that is invisible on these channels is invisible to most of its future customers.
Digital also lets a small company in a tier-2 city compete with national brands: targeting is by intent and interest, not by who can afford the biggest hoarding.
How to build a digital marketing strategy (6 steps)
1. Define one business goal and its number — revenue, qualified leads or app installs — and the cost you can afford per customer.
2. Describe the buyer: what they search, which platforms they use, what stops them buying.
3. Pick two or three channels that match where that buyer already is. Doing three well beats doing nine badly.
4. Fix the destination first: a fast website, a clear offer and working tracking.
5. Launch, then read the numbers weekly — cost per lead, conversion rate, CAC payback.
6. Move budget to winners every month and scale only what is profitable.
How much does digital marketing cost in India?
Costs have two parts: the agency or team fee, and media spend paid to platforms. Freelancers typically charge ₹15,000–₹60,000 a month, small agencies ₹40,000–₹1.5 lakh, and strategy-led agencies ₹1–5 lakh a month plus media.
Magnum Radius publishes its plans openly: Essential ₹1 lakh, Signature ₹2 lakh and Owner ₹3 lakh per month (plus 18% GST), with a 30-day trial.
How to measure digital marketing results
Track business outcomes, not vanity metrics. The core set: customer acquisition cost (CAC), return on ad spend (ROAS), conversion rate, lifetime value (LTV) and marketing efficiency ratio (MER — total revenue divided by total marketing spend).
Likes and followers matter only if they lead somewhere measurable.
Digital marketing as a career
Common roles include SEO specialist, performance marketer, social media manager, content strategist and marketing analyst. Entry salaries in India commonly start around ₹3–5 lakh a year; specialists who can prove revenue impact earn many times that. Hands-on practice with real budgets matters more than certificates.
