How Serebii.net Grew RPS by 3x and Total Ad Revenue by 283% YoY

The Challenge: A Relationship That Stopped Working

For a publisher like Serebii, the right monetization partner isn't just about revenue. It's about trust. When the relationship with their previous ad network started deteriorating, the technical problems weren't even the worst part.

The issues accumulated slowly. Minor friction points piled up, communication became less personal, and when genuine technical problems surfaced with the ad scripts, the response from the other side was deflection. At one point, the previous provider attributed the problems directly to the publisher, until Serebii's team demonstrated that removing the ad script made the problems disappear entirely.

Compounding the damage: a script-level data issue from that provider was quietly suppressing both programmatic signal quality and silently hurting organic search performance. That's not a small problem.

That kind of experience erodes confidence fast. When Playwire reached back out after a previous working relationship, the timing was right for a change.

Finding Playwire: A Familiar Face at the Right Moment

The path to Playwire wasn't a cold search. Our team had stayed in touch and made the case patiently over time. When things finally came to a head with the previous network, Serebii's team had a ready option with a team they already had reason to trust.

The integration itself was handled carefully. Rather than rushing the changeover, the team prepped everything in advance and held off on going live until the first week of January, avoiding the holiday period entirely and ensuring a clean, controlled switch.

Visitors to the site noticed nothing. No layout disruption, no performance dip, no visible change. For a publisher who'd built its reputation on consistency, that was the only acceptable outcome.

Keeping the User Experience Intact

Serebii's team was explicit from the start: the site layout was not on the table for negotiation. No video. No skins. No high-impact interstitials. Options for additional ad units were presented, and politely declined. We believe that each publisher owns their monetization strategy, and our role is to support it.

That balance between monetization and experience is one of the harder problems in publisher ad ops. Many platforms push for maximum unit density because it serves their short-term yield numbers. Respecting a publisher's position on UX and optimizing within those constraints rather than around them is a different kind of work. It's also the work worth doing.

What makes the results below particularly meaningful is the setup: two display placements, top and bottom, nothing else. Every dollar of improvement came from demand quality and optimization, not from adding inventory.
