Plan for more than one creative per campaign

A first paid test can start with one approved 300x250. A campaign you intend to keep running should not stay on one creative by habit.

A read-only sample from a larger adops seat, not our buyer accounts, counted creative associations on 80 line items: minimum 1, median 5, 75th percentile 6, maximum 46. We publish those counts as an operator reading, not as an Adprime Zero fleet statistic. Our own early tests are often one creative on purpose. That is a measurement choice. It is not evidence that one creative is the right steady state.

The public product already has the objects. campaign_creative_associations plus ztdsp campaign creatives and the MCP creative tools can list, add, replace, pause, resume, remove, or copy. The API blocks pause or remove of the final active association. Rotate creatives on a live campaign is the rule page.

How we will use more than one

Keep one promise per campaign. Add variants inside that promise: headline, image, or landing template. Do not mix a new audience and a new claim on the same association set and then call the result "rotation." Template variants inside one promise is the isolation page. Copy a campaign instead of editing is what to do when the next change would mix the first test.

Automated performance-based rotation is not the current product path. Even or weighted serving of approved associations is. Do not invent a "the winner stays" story from remnant CTR.

We will not claim that five creatives raised conversion rate. We do not have that test on this seat yet. The claim here is narrower: do not treat a single banner as the end of creative work just because the campaign is live.
