Digital marketing term
Dynamic Creative Optimization (DCO)
Dynamic Creative Optimization is an automation technology that automatically combines and tests different image, headline, and copy components to show each user the best-performing ad combination.
Detailed explanation
This system combines the multiple images, headlines, descriptions, and call-to-action options an advertiser uploads in real time, and the algorithm learns which combination performs best for each user segment and begins showing it.
Because it can evaluate far more variations simultaneously than manual A/B testing, it offers a significant time and efficiency advantage, especially for large-scale, highly segmented campaigns.
This approach is often combined with large datasets like a product catalog in remarketing campaigns to deliver personalized creative to each user.
