Blind creative back-test
Hide the outcomes. Freeze the ranking. Then reveal the truth.
A blind back-test lets your team evaluate Kettio on its own historical creative while keeping the real CPA, ROAS, or purchase results sealed.
Decision layer
A credibility test with an audit trail.
Candidate IDs, creative files, audience context, ranking output, and outcome data stay separated until the prediction is frozen.
Read metric definitions and boundaries →One matched workflow
Hold the context steady. Rank the creative. Validate the shortlist.
Seal the outcomes
Keep CPA, ROAS, purchases, and winner labels away from the ranking workflow.
Freeze Kettio’s call
Record the shortlist, order, confidence, rationale, and timestamp before the reveal.
Score the result
Compare the frozen call with the predefined winner metric—without changing the definition afterward.
