What Does a Digital Marketing Agency Do?

A digital marketing agency manages the channels a business uses to reach customers online, typically including SEO, paid advertising, content marketing, email, and social media. Most operate as an outsourced marketing department, handling strategy and execution that an in-house team either lacks the headcount or the specialized skill to run alone.

Scope varies enormously between agencies. Some specialize in one channel, like SEO or paid ads, while full-service agencies cover several channels under one retainer. Before hiring, get a written breakdown of exactly which channels and deliverables are included each month, since the term agency covers a very wide range of actual services.

On the SEO side specifically, many now run that piece through SEO software built for agencies to keep content output high without a full in-house writing team.
