Questions about creative testing
Yes. These are examples of what you can create. Describe your own app or recurring job in chat, using your connected data and available tools. Review the result and refine it in the same conversation.
Start by describing the job as you would to a colleague. Ask for the views, metrics and rules you need, review the result, and ask for changes. Your team can create and adjust apps and agents in plain language.
A ranking shows observed performance under its attribution basis. It helps select concepts and audiences to investigate, but it does not by itself establish lift. A suitably designed experiment can estimate incremental impact for what was tested; channel-level calibration should not be read as creative-level proof.
Creative testing is the practice of running ad creatives against each other under controlled conditions so you can tell which ones actually perform, rather than which ones happened to run during a good week. Done properly it isolates the creative variable (same audience, same budget logic, same window) and measures the result on profit rather than surface engagement.
Fatigue shows up as declining performance at stable spend and frequency creeping up while conversion rate falls. The trap is that blended ROAS often hides it, because a strong new asset masks several decaying ones. Dema tracks performance per asset over its lifetime, so the decay is visible at the level where you can act on it, swapping one creative rather than pausing a whole campaign.
A clear hypothesis per test, one variable at a time, a decision rule agreed before the test runs, and a minimum sample defined up front. The part most teams skip is the decision rule: without one, results get interpreted after the fact to support whatever was already planned.
ROAS tells you revenue per unit of spend, which means two creatives can post identical ROAS while one sells high-margin products customers keep and the other sells low-margin products that come back. Dema evaluates creative on contribution margin, so the winner is the asset that actually made money.
Yes. Dema can generate on-brand assets guided by your brand style and real product data, and analyse performance by format, asset, and audience. The measurement side is what tells you which generated assets are worth scaling.
