Test run byDave DiederenSyntra Labs
Commentary byLiftArchiveOur analysis, not theirsPlacing an offer card inside the collection product grid lifted revenue per visitor by 20.70% in Dave Diederen's test, from $2.32 to $2.80. Conversion rose 20.13% and profit per visitor rose 20.22%. Average order value did not change.
- Revenue per visitor: +20.70% ($2.32 to $2.80), about $36,727 more per month on the dashboard estimate.
- Conversion rate: +20.13% (3.48% to 4.18%). More visitors ordered.
- Profit per visitor: +20.22% ($1.48 to $1.77), so the discount did not wipe out the gain.
- Average order value: no change ($66.78 vs $67.10).
- All ranges cross zero (revenue per visitor -20% to +80%), so the win is likely but not certain.
The change
The variant swaps one product slot in the grid for an offer card.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
A standard two-column collection grid of product cards, each with an image, title, sale price and quick-add button.
Variant
The same grid with one product slot, in the second row, replaced by a dark card reading "Get Up To 40% OFF" with the line "Bundle and Save Big".
Why it likely won
Our reading of the result, not the practitioner's claim.
- the card is shaped like a product, so shoppers scrolling the grid notice it instead of skipping it like a banner.
- it shows the offer early, before shoppers tire of comparing products.
- the card brings the offer to where shoppers are already looking, with no popup to dismiss.
Caveats: The ranges are wide and sample size and duration were not shared. Flat order value means the bundle offer did not raise basket size here.

How to run this test on your store
- Hypothesis
- If we put our main offer as a card inside the collection grid, then more visitors will buy because they see the deal while browsing products, not in a banner they skip.
- Primary metric
- Revenue per visitor
- Guardrails
- Profit per visitor
- Average order value
- Product card click-through
- Who should test it
- Stores with a standing bundle or volume offer and busy collection pages. If you have no real offer, an empty promo card just takes a product slot.
Questions
Should I put promo cards in my product grid?
In this test, one offer card lifted revenue per visitor by 20.70% and profit per visitor by 20.22%. The ranges were wide, so test it yourself.
Where should the offer card go in the grid?
Here it took the fourth slot, in the second row on mobile, so shoppers saw it early in their scroll.
Does a bundle offer card raise order value?
Not in this test. Average order value stayed flat; the gain came from more people ordering.
