Build-your-own box options on product page: +35% conversion
Test run byConversion FanaticsCRO agency
Commentary byLiftArchiveOur analysis, not theirsGiving shoppers more ways to build their own box lifted conversion from 1.75% to 2.36%, a 35% gain.
Conversion Fanatics ran this test for a clothing company selling custom boxes.
Several selection changes went live together, so the lift belongs to the new product page as a whole, not to one option.
- Conversion rate: 1.75% to 2.36%, a 35% lift in completed orders.
- Revenue per visitor: up 30%, so the extra orders were not just cheaper ones.
- Cart click-through: up 72%, which shows more shoppers moved past the product page.
- 44 extra sales and $2,118 in extra revenue during the test. The agency projected over $75,000 a year, which is an estimate, not a measured result.
The change
The variant adds style, quantity, size chart and purchase-type choices.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
A simple product page with one large image. Shoppers could only choose a size and whether to subscribe.
Variant
The page highlighted a build-your-own box. Shoppers picked from two styles, chose a quantity, chose a size with a size chart in a lightbox, and picked monthly or one-time purchase.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Choosing a style and quantity can make the box feel personal, which may raise intent to buy.
- A size chart close to the size picker likely cut doubt about fit, a common reason clothing shoppers stall.
- Showing monthly and one-time side by side may have helped shoppers who were not ready to commit to a subscription.
- A clearer, more guided page probably made the next step obvious, which fits the large jump in cart clicks.
Caveats: The test ran for just under two weeks and several selection changes shipped together. No sample size or confidence level was shared.

How to run this test on your store
- Hypothesis
- If we let shoppers build their box with style, quantity, size and purchase-type choices, then more will order because the product feels tailored and fit doubts are answered on the page.
- Primary metric
- Completed orders per visitor
- Guardrails
- Revenue per visitor
- Return or exchange rate
- Subscription cancellation rate
- Who should test it
- Stores selling configurable boxes, kits or bundles, especially apparel where fit matters. It probably won't help a single-SKU product with no real choices to offer.
Questions
Do more product options hurt conversion?
Not always. Here, more choices lifted orders, likely because they were simple and helped shoppers make the box their own.
Too many unclear options can still stall shoppers, so test it.
Should a size chart open in a lightbox?
A lightbox keeps shoppers on the product page while they check fit.
In this test it was one of several changes, so its own effect is unknown.
Should I offer one-time purchase next to a subscription?
Offering both lets hesitant shoppers buy without committing.
Watch subscription share and revenue per visitor to see if the trade-off pays.
