Dynamic Creative Optimisation
Branding & StrategyAlso: DCO · Dynamic Creative
Quick definition
Dynamic Creative Optimisation (DCO) is a technology that automatically assembles and tests different combinations of ad elements, such as headlines, images, prices and calls-to-action, then shows the best-performing combination to each audience segment in real time.
How it varies across Australia
Adoption of Dynamic Creative Optimisation among Australian advertisers is concentrated in ecommerce and retail, where catalogue size makes manual ad variants impractical. Smaller Australian businesses with limited product ranges rarely see enough scale to justify the setup cost.

Dynamic Creative Optimisation (DCO) works like a vending machine stocked by your creative team. You load in the ingredients, headlines, product images, prices, background colours, calls-to-action, and the machine assembles thousands of combinations, then serves whichever one performs best to each viewer based on their behaviour or segment.
It sits downstream of your creative strategy, not instead of it. DCO can test whether "Free shipping" beats "20% off" as a headline, but it can't tell you whether your brand positioning is wrong or your offer is uncompetitive. It optimises within the boundaries you set. Feed it weak assets and it will very efficiently find the least weak combination.
The technology overlaps heavily with retargeting and programmatic display, and it pairs naturally with a-b-testing at scale rather than one variant at a time. Most platforms report results through some form of attribution model, so the "winning" combination is only as trustworthy as the model behind it.
The businesses that get value from DCO are usually running large product catalogues or high ad volume, where manual creative production can't keep pace with the number of audience segments being targeted.
DCO doesn't write good ads. It just finds the least bad combination faster than a person could.
How it shows up
DCO shows up as feed-based ads in Meta and Google display campaigns, where the same ad slot shows different products, prices or messaging depending on who's viewing it and what they've browsed before. It also appears in retargeting sequences that shift messaging based on how far a visitor got through a checkout funnel. Agencies pitch it heavily for ecommerce clients with large catalogues and frequent price or stock changes.
The Australian context
Australian ecommerce brands running DCO through Meta or Google need to keep an eye on ACCC rules around pricing claims. Dynamically generated ads that pull live pricing or stock data can accidentally serve outdated discounts if the feed isn't synced properly, which creates a genuine compliance risk, not just a brand embarrassment.

Common questions
Is Dynamic Creative Optimisation the same as A/B testing?
No. A-b-testing usually compares a small number of fixed variants against each other. DCO assembles many combinations from a library of creative elements and continuously shifts spend toward whichever combination performs best, often per audience segment rather than as a single winner.
Do small businesses need DCO?
Rarely. DCO earns its setup cost when you have a large product catalogue or high ad volume across many segments. A business with a handful of products and simple offers gets more value from manually testing a few strong creative directions.
Which platforms support Dynamic Creative Optimisation?
Meta Advantage+ Creative, Google's responsive display and demand generation ads, and dedicated DCO platforms like Smartly and Celtra all offer some version of it. Capability and control vary significantly between them.
Can DCO hurt brand consistency?
Yes, if left unchecked. Because combinations assemble automatically, some outputs can pair mismatched tones or images that a human would never approve. Regular audits of live combinations are necessary to catch this before it damages the brand.
