What is a digital marketing specialist, and what do they do?

A digital marketing specialist plans, runs and measures a brand's online marketing. The real question for a business owner: hire a specialist, or work with a team?

A digital marketing specialist is a professional who plans, executes and measures a brand's online marketing. Ads, SEO, social media, email and analytics are the core areas of the role.

What does a digital marketing specialist do?

  • Analyses the audience and competitors.
  • Sets up and optimises Google Ads and Meta campaigns.
