Test whether a close-up demonstration reduces repeated questions

A close-up trial should target one recurring visual question and keep the surrounding explanation comparable.

A practical procedure

1. Select a detail repeatedly asked about and define how matching questions will be counted.

2. Add a close-up showing that detail while keeping the product and offer unchanged.

3. Compare repeated-question patterns and check whether viewers joined before or after the demonstration.

Worked example: a fictional session

A fictional lid trial adds a latch close-up and separately records opening questions from viewers who arrived later.

Check the limits

Fewer repeated questions could reflect fewer viewers, so retain audience and duration context.
