Yes. It was just a color test. And it delivered +12.7%.

Not every win needs a strategy workshop.
Sometimes you just need contrast.

Recommended products in cart? Sounds like a guaranteed win.

But on this store, they created friction instead of increasing basket size.

By showing recommendations only on the first cart visit, and hiding them when customers returned, purchases increased by +39.8%.

💡 Real optimisation isn’t about copying what works elsewhere.
It’s about adapting to how YOUR customers behave.

Fixing one leak feels like progress.

In this test, removing the cart page from the user journey increased begin checkouts by +23.8%.

But purchases moved by only +1.5%.

When one stage improves dramatically and the final result barely shifts, the funnel is telling you something.

Optimisation isn’t about one win.
It’s about following the flow... stage by stage.

Most teams look for big changes to increase sales. But sometimes growth comes from a tiny layout shift.

By placing the Add to Cart button directly under the price, this store increased Add to Cart actions by +4.4%.

When people see the price, they’re deciding.
If the button isn’t right there, hesitation creeps in.

Small change. Scalable impact.

We changed one thing.

Not the layout.
Not the copy.
Not the offer.

Just the button color. Most brands optimise for harmony.
But harmony doesn’t always command attention.

In this test, the visible option outperformed the on-brand one. Because if users don’t see it -
they won’t click it.

In this test, delaying the checkout prompt by one minute after add to cart outperformed both immediate and quantity-based triggers — resulting in a +15.9% conversion lift.

💡 Takeaway:
Always test at least three trigger types, in this case, immediate, quantity-based, and time-based.
Only real data will tell you when your users are truly ready.

Most stores still force users to click into product pages just to buy.

We did the opposite.
By adding Add to Cart buttons directly on category and homepage listings, Add to Cart actions increased by 46.64%.

💡 Sometimes shoppers don’t need more details → they just need the product.

Sometimes removing friction means removing freedom.
Sometimes… it doesn’t.

By closing the checkout flow, desktop users converted more easily...
but mobile users needed flexibility at the first step.

We often assume that more product recommendations increase basket size.

But returning cart visitors aren’t browsing. They’re deciding.

On this store, hiding product recommendations at the bottom of the cart page only on repeat visits increased purchases by +39.8%.

Not because we added something. Because we removed distraction.

💡 Optimisation isn’t about adding modules. It’s about protecting intent.

Sometimes optimisation isn’t about adding more. It’s about removing friction.

In this mobile test, we skipped the cart entirely - sending users straight from Add to Cart to checkout.

📈 +23.8% more begin checkouts
📈 But only +1.5% more completed purchases

That’s the real lesson.

When you remove one bottleneck, the next one becomes visible.

Growth doesn’t come from one bold move. It comes from improving the funnel step by step.
