How Smartwatchmagazijn Drove **€10,000+ Monthly Growth** Through A/B Testing

‍

About the Customer

‍Smartwatchmagazijn.nl is a Dutch Shopify store specializing in affordable, stylish smartwatches for everyday use. Known for offering competitive pricing and fast shipping across Europe, they cater to a broad audience seeking feature-packed wearables without the luxury price tag.

Their catalog includes a variety of models designed for fitness, lifestyle, and tech-savvy shoppers—making them a go-to destination for practical smartwatch solutions that look good and perform well.

From Instinct to System: The Backstory

By mid-2024, Smartwatchmagazijn had already carved out a strong niche in the European wearables market. They had demand, solid margins, and strong paid acquisition channels—but their growth still relied heavily on instinct.

“We knew our gut instincts were good—but they weren’t scalable,” says Robbert Weimer, owner of Smartwatchmagazijn.nl.

“We needed a way to validate decisions faster and grow without increasing ad spend.”

That was the turning point. In search of a system they could trust, the team implemented ABConvert to start testing hypotheses—on price, layout, and offer structure—with real data.

507 Experiments Later: What the Data Reveals

Robbert’s team didn’t just install ABConvert—they made it part of their growth process. Since onboarding, they’ve launched 507 experiments, putting them in the top 1% of merchants by testing volume on the platform.

And they weren’t testing fluff.

• Template tests included upsell placements, CTA reordering, layout shifts, and mobile optimizations.
• Price tests covered everything from €10 deltas to shipping bundle value comparisons.
• Most tests had statistically valid outcomes in under 5 days.

Instead of waiting for monthly reports or gut feels, they built a machine that generated learning every single week.

The Breakthrough Moment: €10,000/Month Uplift

One of their early tests captured the power of offer framing perfectly.

They compared two versions of a product bundle:

• €79 with standard shipping
• €89 with free express shipping

The higher price point not only held conversion—it increased average order value (AOV) dramatically. Customers valued the perceived upgrade in shipping speed more than the small increase in price.

“After just one month, our monthly revenue had grown by 25% — without more traffic or higher ad costs,”
“ABConvert costs €59/month and delivered over €10,000 in additional revenue.”

The real win? This wasn’t a lucky test—it became a repeatable playbook they applied across multiple products.

How They Run Experiments: Inside the Playbook

What makes Smartwatchmagazijn different isn’t just what they test—it’s how they test.

Their Testing Cadence

• 2–3 experiments launched every week
• Mondays are for test planning, Tuesdays for launch
• Fridays = decision day (deploy or discard)
• Each test runs ~4 days to hit statistical confidence

Ops Tactics That Keep It Running

• Winners are tagged directly in Shopify for fast rollout
• Theme edits are scheduled early to avoid weekend blockers
• Results are logged in a shared Google Sheet with learnings, actions, and next-test ideas

“We treat testing like product development,”

‍

Robbert says.

“We don’t just run a test—we document it, learn from it, and systematize the rollout.”

This approach ensures the learning doesn’t live in someone’s head—it becomes part of the business DNA.

Real Lessons for Other Shopify Merchants

Smartwatchmagazijn’s growth wasn’t a fluke—and you don’t need 500 tests to get started. But here’s what you can learn from them:

1. Start Where Revenue Lives

They didn’t waste time on button colors or popups. They tested pricing, offer structure, and layout—the stuff that moves revenue.

2. Speed Compounds

The more you test, the more you learn. The more you learn, the faster you grow. Weekly testing gives you more feedback loops—and more control.

3. Be Surprised

Some of their biggest wins were non-intuitive. That’s the value of data—it proves or disproves what your gut can’t.

4. System > Spark

The real unlock wasn’t one experiment—it was a repeatable system. Testing became a ritual, not a rescue plan.

Merchant Quote

“Once you know what works, you can apply it across your entire store—and keep testing new ideas for even better results.”
