Case Study 1: Coca-Cola’s Journey to Personalization at Scale

Coca-Cola faced a challenge familiar to global brands: how to maintain personal connections with consumers across diverse markets while managing massive advertising budgets efficiently. Their solution centered on programmatic advertising to deliver personalized creative content at unprecedented scale.

The Strategy

Coca-Cola’s programmatic approach focused on dynamic creative optimization (DCO) combined with real-time bidding across multiple channels. The brand developed a comprehensive data management platform that integrated:

First-party customer data from loyalty programs
Third-party demographic and behavioral insights
Real-time contextual signals like weather, location, and time of day
Cross-device tracking to maintain consistent messaging

The campaign launched across display, video, and mobile platforms simultaneously. Coca-Cola’s programmatic setup automatically adjusted creative elements—including imagery, messaging, and calls-to-action—based on individual user profiles and environmental factors.

For example, users in warmer climates saw refreshing summer imagery during peak afternoon hours, while colder regions received cozy, warming visuals during evening commutes. The system processed over 100 variables to determine the optimal creative combination for each impression.

Results That Matter

The programmatic campaign delivered exceptional performance metrics:

67% increase in click-through rates compared to traditional display advertising
45% improvement in brand recall scores across target demographics
23% reduction in cost per acquisition through automated bid optimization
