Flyco sells personalised hard-shell luggage across Singapore and Malaysia. Every bag carries the buyer's name plus their choice of font, handle, wheel and luggage colour, which makes the product page the most important screen in the business. Convx by Z21 took that page apart, rebuilt it, and then kept testing it.
1. The product page was the largest leak in the funnel: Almost every product view ended without an add to cart, running roughly three percentage points below the luggage category benchmark. Traffic was arriving in volume and the page could not convert it.
2. Five customisation choices arrived at once: Luggage colour, handle colour, wheel colour, font colour and the name field were all presented at the same time, in a flat list, before the buyer had settled on a size. The feature the brand competes on was the same feature stalling the decision.
3. The page argued with itself: Marketing copy led above the fold instead of the product. Colour options sat three scrolls down. A countdown timer held the space where trust signals belonged, while duplicate trust blocks, floating buttons and repeated copy competed for the same attention.
4. Sizes were described in inches, not in trips: Buyers had to choose between 20, 24, 26, 28 and 32 inches with no guidance on what any of it meant for the way they travel. For someone buying their first piece of personalised luggage, that is where the session ends.
1. Fix The Product Page Before Anything Else
2. Sequence The Customisation Journey
3. Rebuild Trust Above The Fold
4. Prove Each Change, Then Keep Testing
The traffic was already being paid for. The product page was losing the buyers it brought in.
1. No site redesign. The product page was rebuilt first because it was the largest measurable leak, and every later change had to earn its place against that page.
2. Customisation was sequenced, not reduced. Size first, then one guided design step, then add to cart.
3. Anything that did not help the decision came off the page, including the countdown timer. Page length dropped by half.
4. Changes were shipped and measured, and the questions worth settling properly went into A/B tests. Winners scaled, losers reverted.

The old above-the-fold zone opened with a line of marketing copy and a dark studio image, with no price and no add to cart in view. We rebuilt it around the product: the personalised bag first, then the series name, then the price, then a full-width add to cart, all before the first scroll. Specifications collapsed into scannable sections, and a trust row covering shipping, lifetime warranty and WhatsApp support took the space the countdown timer used to hold. Add to cart repeats at the foot of the page so it stays within thumb reach.
Measured across a two-week window against the two weeks immediately before it, with both the rebuilt product page and a new theme live:
Results:
+53% sales
+40% conversion rate
+43% add-to-cart rate
+56% reached checkout
+60% returning customer rate
all on +3% sessions

The five selectors were not removed, they were ordered. Size comes first and is framed around the trip rather than the tape measure. Everything to do with appearance then sits inside a single "Design your luggage" card, where font colour, the name field and handle colour follow in the order a buyer actually decides them. Add to cart sits directly beneath.
Size: the inch measurements were nested under trip length, "Cabin (1 to 4 days)" and "Check-in (7 to 14 days)", so the first choice is about the trip rather than the tape measure
Personalisation: the name field moved out from under the colour selectors into its own card with a live preview and a character count
Scarcity: the countdown timer and the stacked free-gift claims that broke up the sequence were removed
Depth: product page length reduced by half

Two questions were worth settling with a controlled test rather than a judgment call.
On mobile, the colour swatches still sat below the price next to a block of discount-code copy. We tested lifting the swatches above the fold and removing that copy block. Engagement moved, and it carried through the funnel rather than stopping at the click:
Results:
+30.8% colour swatch click rate
+11.3% add-to-cart rate
+20.0% checkout rate
rolled out to all traffic
The second test moved the "your products are reserved for" countdown on the cart page below the fold, across two variants. Revenue per visitor fell and checkout rate fell. We concluded it as a loss and kept the control.
Urgency mechanics are where instinct is least reliable. Taking the countdown off the product page was part of the rebuild and the funnel improved. Demoting the countdown on the cart page was a controlled test and it lost. Same mechanic, opposite answers, one page apart.
Across four consecutive months, conversion rate improved every month. None of that came from buying better traffic, because media was never part of this scope.
Results:
2.2x conversion rate
+127% orders
four consecutive months of conversion-rate improvement
The rebuilt product page and the theme migration went live close together, so no single change takes full credit for the movement in the funnel. What the work changed is how much of the existing traffic the page could convert. The same visits, asked to make fewer decisions in a clearer order, produced more than twice as many orders.
About the figures. Conversion rate is orders as a share of sessions, and add-to-cart rate is add-to-cart sessions as a share of sessions, both from the store's own analytics. The four-month figures compare the fourth month against the first. The use-case figures compare a two-week window against the two weeks immediately before it, with both the rebuilt product page and a new theme live in that window, so they measure the two together rather than either one alone. A/B test figures are the platform's results at conclusion. Paid media was run by the client's own team throughout and sat outside this scope. Absolute revenue, traffic and order volumes are held back for client confidentiality.
