Commentary byLiftArchiveOur analysis, not theirsUpdating the product images lifted revenue per visitor by 5.59% and conversion rate by 5.09%. Dave Diederen ran this test right after a full page redesign on the same store lost badly. Profit per visitor rose 5.57%, and average order value did not change.
- Revenue per visitor: +5.59% ($1.22 to $1.29), about +$24,347 per month. The interval runs from -9% to +22%.
- Conversion rate: +5.09% (1.49% to 1.57%), about 270 more orders per month.
- Profit per visitor: +5.57% ($1.04 to $1.10).
- Average order value: no change ($81.99 vs $82.38).
- For contrast, the earlier full-page redesign dropped conversion 71.26% and revenue per visitor 67.45%.
The change
Only the product images change; the rest of the page stays the same
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The product page with its original images.
Variant
The same page with updated product images. The new images themselves were not shown.
Why it likely won
Our reading of the result, not the practitioner's claim.
- images are what shoppers judge a product by, so better images can lift confidence without changing anything else.
- a single change keeps what already works on the page, while a full redesign risks breaking it.
Caveats: The interval for every metric still crossed zero, so the win was not certain. Sample size and duration were not shared.

How to run this test on your store
- Hypothesis
- If we update our product images, then more visitors will buy because they can judge the product more clearly.
- Primary metric
- Revenue per visitor
- Guardrails
- Average order value
- Return rate
- Page load time
- Who should test it
- Stores whose product photos are dated, low quality or don't show the product in use. If your images are already strong, a redesign of other parts may matter more.
Questions
Do better product images increase conversion?
In this test, updated images lifted conversion 5.09% and revenue per visitor 5.59%, with no change in order value.
Should I redesign my whole product page instead?
On this store, a full redesign lost 67.45% revenue per visitor, while the single image change won. Testing one change at a time was safer.
