The variant shrinks the category overview so products appear sooner.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
Collection pages showed a large explanatory category overview above the product grid.
Variant
The category overview was made smaller, so the product grid appeared higher on the page.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Shoppers on a collection page want to see products. A big text block pushes them below the fold.
- Less scrolling makes it easier to compare options side by side.
- Revenue per user rose more than conversion rate, which suggests shoppers who saw more products sooner also bought more.
Caveats: Test KRO-38. Revenue is the total during the test runtime, not an annual figure. DRIP Agency did not publish sample size, test length or statistical significance.

How to run this test on your store
- Hypothesis
- If we shrink the category overview above the product grid, then revenue per user will rise because shoppers see and compare products sooner.
- Primary metric
- Revenue per user
- Guardrails
- Product click-through rate
- Conversion rate
- Organic search traffic to collection pages
- Who should test it
- Stores whose collection pages open with a large banner or text block. If that text supports SEO, keep it but move or collapse it. Stores with a compact header already will see little change.
Questions
Do large collection page banners hurt sales?
They can when they push products out of view.
In this KoRo test, a smaller overview lifted revenue per user by 2.9%.
Will shrinking category text hurt SEO?
The source does not report SEO effects. Keeping the text on the page but placing it lower or collapsing it is a common way to protect rankings.
How much should products show above the fold on a collection page?
There is no fixed rule, but at least one row of products on first view is a sensible target. Test against your current layout.
