Full-width product description layout: +17.5% conversion
Test run byElevate_abTesting and CRO tool
Commentary byLiftArchiveOur analysis, not theirsMoving the product description into a full-width section below the images and add-to-cart button, along with some minor design tweaks, lifted conversion from 4.46% to 5.24% (+17.5%).
JuvaBun, a hair extensions brand, ran the test on its Messy Bun product page with the Elevate A/B Testing app.
Because several changes shipped together, the lift belongs to the redesign as a whole, not the layout move alone.
- Conversion rate: 4.46% on the old layout vs 5.24% on the new one, a relative lift of about 17.5%.
- Revenue: Elevate reports about $2,493 extra per 10,000 visitors during the test.
- Monthly gain: the vendor projects about $12,466 a month from 50,000 visitors. This is an estimate.
The change
The description moves from the side column to a full-width section.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
Images sat on the upper left and the add-to-cart options on the right. Product details, extra images and gifs were stacked in the right column below the add-to-cart section.
Variant
The product description became a full-width section below the images and add-to-cart button, which shortened the scroll to reviews. Other minor design changes were made at the same time.
Why it likely won
Our reading of the result, not the practitioner's claim.
- A narrow, crowded right column makes details hard to read. A full-width section is easier to scan.
- Reviews came into view sooner, and reviews are often what convinces a hesitant shopper.
- The other design tweaks may have played a part, so the layout change can't take all the credit.
Caveats: This was a bundled change: the layout move shipped with other minor design adjustments. No sample size, duration or significance was shared, and the monthly figure is a projection.

How to run this test on your store
- Hypothesis
- If we move the product description out of the narrow buy-box column into a full-width section, then conversion will rise, because details and reviews become easier to reach and read.
- Primary metric
- Conversion rate
- Guardrails
- Add-to-cart rate
- Scroll depth to reviews
- Revenue per visitor
- Who should test it
- Stores with long product details squeezed into a side column on desktop. It matters less if most traffic is mobile, where content already stacks full width.
Questions
Where should the product description go on a product page?
Key points belong near the buy button. Longer details often read better in a full-width section below, as in JuvaBun's winning layout.
Does it help to bring reviews higher up the page?
Often, since reviews answer doubts. JuvaBun's new layout cut the scroll to reviews and converted better, though other tweaks shipped too.
Can I test a layout change with other tweaks included?
Yes, but you only learn that the package works.
Test single changes afterwards if you want to know which part mattered.
