Quiz & Product Finder benchmark report for eCommerce
"Our quiz converts at 6%." Without a reference point that's just a number. Here are the reference points: completion, conversion, revenue and list growth from 130,000+ live quiz sessions on bluebarry stores.

The 5 most important metrics, analyzed.
Check them in this order. Completion first, because nothing after it counts if shoppers bail halfway.
The health metric. Completion rate.
Completion is the share of shoppers who start a quiz and reach the result page. Across live finders the average is 89%; top performers hit a 94% median. Our internal bar is 80%: a finder below that gets fixed, not ignored.
“Which wattage?” instead of “What do you want to power?”
The 90%+ group asks 5 to 8 questions about the shopper's situation. Not about the product's specs.
Conversion: what a completed session is worth.
Stores convert 4 to 29% of completed sessions into a purchase. The range is wide because placement and price point dominate: a €15 skincare product on a PDP mini-quiz converts very differently from a €2,000 e-bike finder, where the "win" is often a store visit or a quote.
PDP mini-quiz, +10% AOV
Return on tooling: settle budget discussions.
€11 attributed revenue per completed session, median across the set. Measured against software cost, top stores earn back 26x to 373x their subscription; the median sits around 55x. The spread is mostly traffic: the finder's cost is fixed, its output scales with every session.
Inside the 26x–373x benchmark range. Median is ~55x.
Which is why the busiest placement on your store is the right first home for a finder.
Profiles, not addresses.
A quiz with an email step grows your list with preferences attached. Powerstationshop grew theirs 200% in three months, and every signup arrived with answers: what to power, for how long, at what budget. Data your email flows can segment on from day one.
The benchmark to watch isn't the growth percentage. It's the trade: shoppers leave an email when the result is worth keeping. Deliver the recommendations by email, and the email step helps completion instead of hurting it.
