JAPANNEXT: +64% revenue on Amazon, in 4 countries at once

JAPANNEXT sells PC monitors on Amazon (office, gaming, 4K, 5K and 6K) in 4 countries: France, Germany, Italy and Spain, through a seller account. We have managed its Amazon advertising since October 2025.

Before we arrived, advertising brought traffic but converted it poorly: fewer than one ad click in 130 ended in an order. Italy, the weakest market on the account, ran at a ROAS of 6.

Our brief: grow all 4 markets at the same time, with a ROAS target set from the start.

We run its Sponsored Ads campaigns across the 4 markets with four rules:

• Fewer keywords, held better. From November 2025, targeting was narrowed to the searches that sell, held all day rather than in bursts.
• Country by country. Each market has its own ROAS and TACOS targets. Germany is not run like France, and Italy, the weakest at the start, received the most budget. In France, February 2026 sold more than a year earlier with 44% less budget.
• Cut what does not convert. The portable monitor range was not converting: its campaigns were stopped at the end of May and the budget moved back to the best sellers.
• Clear targets, honest reports. Every report sets next month's targets per market, and the next one says whether they were met. In France, the share of revenue paid in advertising went from 8% in March to under 5% in June 2026. In June, French ROAS reached 11.45 against a target of 12: close, and we report it as is.

November 2025 to June 2026, versus the same 8 months a year earlier (before we arrived, 4 markets combined):

• Total revenue: +64%
• Advertising revenue: ×2.1
• ROAS: 9.77 versus 7.95, with a 70% higher advertising budget
• Orders: +70% across the 4 markets
• Conversion rate: 1.09% versus 0.73%
• Share of revenue paid in advertising: stable at 5.1%

Up year on year in all 8 months. January 2026, three months after we arrived: revenue +152% year on year.

Market by market

Change in revenue, orders and ROAS, same periods:

• Italy: revenue +153%, orders +139%, ROAS from 6.0 to 8.9
• France: revenue +53%, orders +50%, ROAS from 8.2 to 13.0
• Germany: revenue +45%, orders +60%, ROAS from 7.6 to 9.1
• Spain: revenue +54%, orders +69%, ROAS from 10.9 to 8.2: it fell. Sales grew, but each euro of advertising brings in less there than before.

The peak: Black Friday 2025

November 2025 versus November 2024, 4 markets, budget up 25%:

• Total revenue: +115%
• ROAS: 11.87 versus 7.55, above the target of 11
• Advertising revenue: +96%
• Orders: +92%
• 34% fewer impressions, and a conversion rate of 1.14% versus 0.67%

The period ends in June 2026: since the summer, part of the catalogue has been moving from the seller account to an Amazon Vendor account, so the following months no longer compare like for like. We run the advertising on both sides.
