TRILL – one of Japan’s largest lifestyle publishers – partnered with Browsi to increase ad revenue while keeping user experience intact. Using Browsi’s no-code optimization suite, TRILL launched advanced multi-variant tests across ad layouts, viewability thresholds, and timeout settings, all without touching a line of code.

The result? A +7% uplift in RPM from surfacing high-value inventory previously left untapped.

The Opportunity

TRILL is one of the leading lifestyle media publishers in Japan, operated by dely Inc. The platform serves millions of monthly readers with high-quality content spanning fashion, beauty, wellness, and more.

TRILL’s reputation as a mobile-first, user-centric destination has made it one of the country’s most visited lifestyle information hubs.

 

The Challenge

TRILL’s AdOps team was at a standstill. Every test they wanted to run-whether for layout, load speed, or timeout optimization-required developer time they didn’t have.

Simply adding more ad units wasn’t an option either. That could jeopardize UX, break policy compliance, and slow down page performance.

At the same time, campaign fill rates were high, yet RPM had plateaued, hinting at inefficiencies they couldn’t see, let alone fix. TRILL needed a new approach to unlock growth without risking the user experience or overloading their dev team.

 

The Stellar Outcomes

TRILL’s hands-free testing strategy led to measurable wins:

• Rethinking Static Placements: +7% RPM
  By removing legacy hardcoded ad slots and replacing them with dynamic placements managed by Browsi, TRILL unlocked impressions that had been sitting unused.
• Viewability Threshold Optimization: +5% RPM
  A/B/C testing across different viewability levels showed where the real revenue sweet spots were, uplifting RPM without overloading pages with extra ads.
• Prebid Timeout Tuning: +5% RPM
  TRILL split timeout settings across four variants to find the ideal balance between speed and bid response.

Full compliance in mind: 

• Ad density safeguards: holding back requests when a page neared its ad limit
• UI optimizations: extra padding, background styling, and layout spacing to reduce accidental clicks

 

“We thought we had pulled every lever-until Browsi surfaced hidden inventory and monetized it, all without a single line of code.

Browsi’s A/B testing capabilities are incredibly agile. Whenever we think, “What if we tried this?” we can turn the idea into action immediately, and without any engineering lift. That speed means every result becomes the starting point for the next experiment.

Next up? We’re doubling down-using Browsi to push each placement’s performance even further and build a platform advertisers trust and users love.”
