應用程式廣告活動會藉助機器學習技術來決定廣告素材輪播方式，為適宜的廣告空間、合適的使用者和適當的時機，選擇理想的廣告素材。請問你應該如何運用素材資源，才能獲得出色的成效？

The correct answer is to use diverse ad assets, including varied content, themes, lengths, and orientations. App campaigns leverage machine learning to optimize ad delivery. Providing a wide range of assets allows the system to test different combinations and identify what resonates best with various audiences across different placements and contexts. This diversity maximizes the campaign's ability to find the ideal ad for each impression, leading to better performance. Uploading fewer assets limits the machine learning's optimization capabilities. Providing videos with only minor differences or simply cutting the same video into different lengths doesn't offer enough variety in content or theme to significantly improve performance.
