Global Digital Marketing Agencies

CMOs face pressure to prove agency ROI amid AI disruption and flat budgets. As a result, CMOs are scrutinizing agency spending and reducing the number of agencies on their rosters. This research helps CMOs evaluate the rapidly shifting large, global agency market and form partnerships that drive measurable growth.

Market Definition

Gartner defines global digital marketing agencies as service providers capable of developing and executing global marketing strategies. These full-service agencies bundle their strategic marketing services with an array of complementary offerings and technologies to support their clients’ needs. An agency’s particular combination of offerings and competitive strengths typically correlates to its roots as a traditional advertising or digital agency, or as a management consultancy or systems integrator.

CMOs often turn to global digital marketing agencies to enhance, augment or replace internal marketing capabilities, often working with multiple agencies as part of a roster. Marketers spend nearly as much on these outsourced agencies as they do on internal marketing staff. CMOs report that agencies provide a greater depth and breadth of capabilities than can be found internally and that external agency work output is often of a higher quality. Agencies have relationships with media and technology providers at a greater scale — working on behalf of multiple clients — than a single client organization may have on its own. Importantly, a global digital marketing agency brings global strategy and execution, a cross-industry perspective and proprietary data and technology to a CMO’s brand, and that outside-in perspective is critical to meeting customers’ evolving expectations.
