Preference driven product discovery

Ask only what changes the recommendation. Five to eight questions is the working range: enough to separate shoppers into meaningfully different paths, few enough that people finish. Every question should map directly to products, content, or offers the shopper will see differently because they answered.

## The short answer

Ask only what changes the recommendation. Five to eight questions is the working range: enough to separate shoppers into meaningfully different paths, few enough that people finish. Every question should map directly to products, content, or offers the shopper will see differently because they answered.

## Which questions earn their place?

Good quiz questions have three traits: shoppers can answer them instantly, the answers split your audience into groups that want different things, and each answer triggers a visible change in what gets recommended. Questions about use case, budget band, style direction, and who the purchase is for usually qualify. Questions asked out of curiosity do not.

## What should the team evaluate?

Draft the recommendation outcomes first, then work backward to the smallest set of questions that selects among them. If two answer paths lead to the same product set, merge them. Watch completion rate per question when the quiz goes live; a sharp drop at one question means it is confusing, intrusive, or asking for something shoppers do not know yet.

## How should the result be measured?

Compare quiz matched recommendations against your default on click through, add to cart, and purchase rate. Also measure quiz completion itself, since a brilliant quiz nobody finishes earns nothing. Review the answers quarterly: response distributions shift with your audience, and dead answer options should be pruned.

## Frequently asked questions

### What makes a good preference quiz question?

A good question is one whose answers change what you show. If every answer leads to the same recommendations, the question is decoration. Each question should map to real product attributes in your catalog.

### How many questions should a preference quiz have?

As few as produce a confident recommendation, usually three to six for most catalogs. Every extra question costs completions, so cut any question whose answers rarely change the result set.

### Should quiz questions ask about budget?

Yes, when price genuinely drives the recommendation, and ask it as a range the shopper can answer honestly. Budget answers given early prevent the common failure of recommending a perfect product the shopper will never buy.
