What does a chief digital officer (CDO) do?
A chief digital officer is the executive who owns digital transformation. The title emerged in the early 2010s when companies realized that the web, mobile, data and automation were not an IT project but a change to the business itself, and that somebody at board level needed to own it. The CDO's remit typically spans digital products and channels, customer experience, data and analytics, marketing technology and the culture change required to make a traditional company behave like a digital one.
At an agency the role is narrower and sharper. The CDO leads the agency's digital capability, which means the technology it uses, the digital services it sells, the data it works with and the innovation it brings to clients. They sit beside the chief creative officer and the managing director, and their job is to make sure the agency's ideas can be built, measured and scaled on the platforms where audiences now live.
Why it matters
Why a CDO matters
Every company is now partly a technology company, and most were not built to be. A CDO exists to close that gap at the top, where it can only be closed. Without one, digital initiatives scatter across marketing, IT and product, each with its own vendors, data and definition of success, and the company ends up with a dozen pilots and no transformation. With a strong CDO, digital becomes a strategy rather than a set of projects, with a budget, a roadmap and someone accountable for the result.
For agencies and their clients, the role matters because the work has changed. Campaigns are now systems: content fed into platforms, measured in real time, optimized continuously and connected to commerce. Someone has to understand both the idea and the machinery, and to make sure the agency invests in the tools and people the next five years will need.
In practice
How a CDO works in practice
- 01
The CDO's first job is usually a map: where the company stands on digital maturity, what the customer journey looks like across channels, where the data lives and where it does not, and which gaps cost the most. From that comes a roadmap with priorities, budgets and metrics, which the CDO then drives across departments that do not report to them. Influence and persuasion are most of the work, because digital transformation is mainly a change in how people behave.

Operationally, the CDO oversees digital product teams, the marketing technology stack, data and analytics functions, and partnerships with platforms and vendors. They set standards for how data is collected and used, which has become a legal as well as a technical question. They sponsor experiments, kill the ones that fail and scale the ones that work. And they keep the executive team honest about what digital can and cannot do, which in an age of constant platform hype is a service in itself.
- 03
In an agency, the CDO also sells. They shape digital offers, pitch alongside the creative leadership and make sure the agency's capabilities are real rather than aspirational slides. They are often the person who decides which new platforms the agency learns early and which it waits out, a judgment that saves or wastes a great deal of money over a decade.
- 04
The role runs on a cadence. A quarterly review reads the roadmap against adoption, not launches: how many customers or staff use the thing that shipped. A scorecard reaches the board in the same shape each time. Department heads commit to their part of the change in a standing forum, in writing. Overlapping tools are pruned at a yearly vendor review. And when an initiative is stable, it moves out of the CDO's office into the line department that owns it.
Watch out
What people get wrong about chief digital officers
Confusing the CDO with the chief information officer. The CIO runs the company's technology infrastructure and systems; the CDO uses technology to change the business and the customer's experience of it. The second mistake is confusing the CDO with the chief data officer, which shares the initials and overlaps on analytics but is focused on data governance and value rather than transformation. The third is hiring a CDO without giving them authority or budget, then wondering why the transformation stayed a slide deck. The role only works when the executive team wants to change.
