What Is Dynamic Creative Optimization (DCO)? Let AI Pick the Right Ad for Each Person

Let the system automatically pick the right creative for each person in real time, without building ads one by one

July 20, 2026 5 min read

Ever wondered why two people seeing the same ad get different images or copy? That's Dynamic Creative Optimization (DCO) at work: a system that combines multiple ad elements, such as images, headlines and call-to-action buttons, and automatically picks the best combination for each user in real time.

How is it different from A/B testing?

A/B testing compares two versions to find a single winner for everyone. DCO goes further by building personalised ads from many elements at once. The system learns which groups respond to which visuals and tailors the ad to each person, without waiting for a test to finish first.

How can SMEs benefit?

You don't need a big creative team to start. Just prepare product images from several angles and several promotional messages, then let platforms such as Meta Advantage+ or Google Performance Max mix and match them for you. It saves the team time and usually performs better than a single fixed creative.

Things to watch out for before you start

Although DCO saves time, you need to prepare a varied enough set of creative elements from the start, or the system won't have enough options to combine. Check results periodically too, because automatically combining images and text can sometimes convey a different meaning from what you intended.
