What is Digital Marketing? A Step-by-Step Beginner Guide to Start from Zero (2025)

A few years ago, marketing meant banners, newspapers, pamphlets, and TV ads. Today, things have completely changed. People search on Google before buying anything. They scroll Instagram, watch YouTube reviews, and read blogs before making decisions.

If you are a beginner who has no technical background, no marketing experience, and no idea where to start, this article is written only for you. I’ll explain everything in simple language, with real-life examples, so you can clearly understand what digital marketing is and how it works step by step.
