State the criterion
Add MaxDiff and ask about importance for a concrete decision.

An example to try
When choosing a finance app, what matters most and least?
- Free transfers
- 24-hour support
- Spending tracking
- Virtual card
- Real-time alerts
What you see in results
- Index = (most − least) ÷ exposures × 100, from −100 to +100.
- Read the valid base and exposures; the index is neither a percentage of people nor purchase probability.
Avoid these mix-ups
- Do not mix benefits and brands without a comparable criterion.
- Ties are possible; the index does not have to sum to 100.
