The Basics

What Is a Digital Marketing Agency?

A digital marketing agency is a company that specialises in marketing businesses through digital channels. Unlike traditional advertising agencies that focus on TV, radio, and print, digital agencies focus on online channels where your customers spend their time — search engines, social media, email, and websites.

Think of a digital marketing agency as your outsourced marketing department — bringing together specialists in SEO, paid advertising, content, and social media under one roof.
