Test the choice, not imaginary conversion lift
Ask which option is clearer, more credible, more appealing or more relevant. Do not present a preference result as proof of future conversion performance.
Use realistic stimuli
Show respondents the actual headline, mockup, offer or page treatment whenever possible. Abstract descriptions create avoidable ambiguity.
Define the audience
A preference from the wrong people can be worse than no data. State who the decision is for before collecting responses.
Compare human and AI interpretation when useful
AI evaluator panels can reveal machine-readable clarity and disagreement, while human respondents provide audience preference. Keep those signals separate.
Carry winners into live testing
Use pre-launch research to narrow the field, then measure actual behavior once enough traffic exists.
