Summary

Digital marketing encompasses all marketing efforts that use an electronic device or the internet. It leverages digital channels such as search engines, social media, email, and other websites to connect with current and prospective customers. Understanding the core concepts of digital marketing is crucial for any business aiming to establish an online presence, drive traffic, generate leads, and ultimately increase sales in today’s digital-first economy. This guide outlines the key channels and strategies that form the backbone of a comprehensive digital marketing plan.

The Concept in Plain English

Imagine you own a shop. Traditional marketing is like putting an ad in the local newspaper or handing out flyers. Digital marketing is like opening an online version of your shop, putting up signs on the internet, and talking directly to customers through their phones and computers. It’s about getting found by people searching for what you offer (like showing up high on Google search), chatting with potential customers on social media, sending them personalized emails, and creating interesting articles or videos that bring them to your online store. The big difference? Every interaction can be tracked, measured, and improved, so you know exactly what’s working and what’s not.
