Introduction
Have you ever wondered how brands show up on your Instagram feed or why some websites appear at the top of Google search results? That’s digital marketing in action. In 2025, where the world spends most of its time online, digital marketing is not just a trend—it’s a necessity.
Whether you’re a student thinking about career options after 12th, someone considering a career switch, or a small business owner aiming to grow your brand, this guide is designed to help you understand digital marketing from the ground up. Let’s break it all down.
1. What Is Digital Marketing?
Digital marketing refers to promoting products, services, or brands through digital channels like search engines, social media, email, websites, and mobile apps. Unlike traditional marketing (newspapers, billboards, TV ads), digital marketing focuses on reaching people through the internet and digital devices.
Example: Think of a bakery that posts cake photos on Instagram and takes orders via WhatsApp. That’s digital marketing!
Traditional Marketing vs. Digital Marketing
