In today’s world, customers don’t search for businesses in newspapers or phone directories anymore. They search on Google, scroll through Instagram, watch videos on YouTube, and chat on WhatsApp.
If your business is not visible in these places, you are already losing potential customers.
This is where digital marketing comes in.
In this guide, I’ll explain what digital marketing really is, how it works, why it matters in 2025, and how business owners can use it to grow—without complicated jargon.
Digital marketing is the promotion of your business using online platforms such as:
- Search engines (Google)
