What is digital marketing?

Digital marketing is the promotion of products, services, or brands using digital technologies and channels. Unlike traditional marketing, digital marketing allows for precise targeting, real-time campaign adjustments, and measurable results.

The digital marketing ecosystem

Digital marketing isn’t a single strategy but rather an ecosystem of interconnected channels and tactics:

• Earned media: Exposure gained through word-of-mouth, viral content, and PR efforts

Understanding the modern buyer’s journey is crucial for effective digital marketing:

1. Awareness stage: Prospects recognize they have a problem
2. Consideration stage: Prospects research solutions to their problem
3. Decision stage: Prospects choose a solution provider

Your digital marketing strategy should address all three stages with appropriate content and messaging.
