What is Digital Marketing?
Digital marketing basically is to sell and promote products or services via the internet or digital platforms. It includes anything that helps a business attract and communicate with customers online.
Digital marketing is all about connecting with your audience online, using tools and strategies that can grow your business or brand from anywhere, even from your phone. Let’s break it down:
-
- “Digital” means anything that is done with the use of computers, phones, apps or the internet.
- “Marketing” means reaching people to create awareness and interest in your product or service.
So, digital marketing is about using platforms like Facebook, Instagram, Google, WhatsApp, email, blogs and websites to:
-
- Draw people to your business.
- Educate them about what you offer.
- Convince them to buy from you.
- Keep them coming back.
For example: As a Lagos-based Nigerian entrepreneur dealing in wigs, you can promote on Facebook or Instagram so that people in Surulere, Ikeja, or even Port Harcourt can see your products and buy from you; or if you are a photographer in Abuja, an SEO blog or website can get customers searching for “wedding photographer in Abuja” to you directly from Google.

Common Mistakes to Avoid While Learning Digital Marketing
