I am working on improving monetization and trying to understand which changes really move the needle on RPM.

My traffic mix is mostly Brazil with a strong tablet component.

I have seen cases where fewer placements performed better than more placements, so I am trying to think in terms of quality and page context instead of just stuffing more ads in.

• Main goal: improve CTR
• Open to testing layout, density, and placement changes
• Trying to avoid short-term gains that hurt long-term user behavior
