What is Digital Marketing?
Digital marketing refers to promoting products, services, or brands using digital channels such as websites, search engines, social media platforms, email, mobile applications, and online advertising.
Instead of relying only on television, newspapers, or billboards, businesses use digital platforms to reach customers where they spend most of their time—online.
This is data-driven, allowing businesses to measure traffic, clicks, conversions, customer behavior, and return on investment (ROI).
Example
Imagine you own a bakery.
Traditional marketing would involve handing out flyers.
Digital marketing allows you to:
- Create a professional website
- Rank on Google when people search for “best bakery near me”
- Post photos on Instagram
- Run Facebook ads
- Send discount emails
- Collect customer reviews
- Track every visitor using analytics
