Product images with USPs and proof: +7.17% conversion rate
Test run byDave DiederenSyntra Labs
Commentary byLiftArchiveOur analysis, not theirsProduct images that carried selling points, testimonials, guarantees and delivery details lifted conversion rate by 7.17%. Dave Diederen ran this test for a Shopify brand. Revenue per visitor rose 6.36%, an estimated $31,071 a month.
- Conversion rate went from 5.02% to 5.38%, a 7.17% lift, estimated at about 504 extra orders a month.
- Revenue per visitor went from $3.49 to $3.71, up 6.36%, estimated at about $31,071 a month.
- Profit per visitor went from $2.88 to $3.03, up 5.37%, so the gain held after costs.
- Revenue grew a little less than conversion, which suggests order value dipped slightly. This was not reported directly.
The change
Gallery images now show selling points, testimonials, a guarantee and delivery info.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The product gallery used the store's existing images. The post does not show them, but the test implies they lacked the added messaging.
Variant
The gallery included images that showed key benefits, customer quotes, a guarantee and delivery information alongside the product.
Why it likely won
Our reading of the result, not the practitioner's claim.
- many shoppers swipe the gallery and never read the description, so images are where they meet the selling points.
- a guarantee and delivery info inside the gallery answer risk questions before the shopper scrolls.
- a customer quote on an image adds proof at the moment of interest.
Caveats: Sample size and duration were not shared. The collage in the post shows examples from other brands, not the tested store's actual images.

How to run this test on your store
- Hypothesis
- If we add benefit, review, guarantee and delivery images to the product gallery, then conversion rate will rise because shoppers see the key reasons to buy without leaving the gallery.
- Primary metric
- Revenue per visitor
- Guardrails
- Average order value
- Profit per visitor
- Return rate
- Who should test it
- Stores whose galleries are plain product shots, especially on mobile where the gallery fills the screen. It may add little if your images already carry this messaging.
Questions
What should product images include besides the product?
This test added selling points, testimonials, a guarantee and delivery information. Together they lifted conversion by 7.17%.
Do infographic-style product images increase sales?
On this Shopify store they raised revenue per visitor by 6.36%. The gain held at the profit level too, up 5.37%.
Where should I put these images in the gallery?
The post does not say which slots were used. A common approach is to keep the main photo first and place benefit images in the next few slots.
