What should we bring to a creative test?
Bring the assets or concepts, the audience definition, the decision you need to make, and the questions or measures you want to compare. Agree how each respondent will see the variants before programming; random assignment or rotation helps limit order effects.
How many respondents do we need?
Plan the sample for each variant and audience segment, around the smallest difference that would change your decision. A total sample can look large while individual comparison groups remain small. Check recruitment feasibility and use the sample size calculator before fielding.
Can a creative test finish the same day?
A short study with a readily available audience may field within a day. Narrow targets, low incidence, quotas, asset review, and the sample required for useful comparisons can take longer. Agree the fieldwork plan and decision deadline before launch; statistical significance is not guaranteed.
Does a winning creative test predict sales?
Survey responses show how the recruited audience reacts to the tested assets. Appeal, recall, and stated purchase intent are not sales forecasts. Review uncertainty and the reasons behind the scores, then use in-market performance to learn how the chosen creative works in its actual context.
