在 Search Ads 360 和 Google Analytics 4 之間，下列哪些指標有所不同但仍是互補的？

Conversions in Search Ads 360 (SA360) and Google Analytics 4 (GA4) are often different but complementary. SA360 focuses on conversions directly attributable to search ad clicks, using its own attribution models. GA4, on the other hand, tracks a broader range of user interactions across various channels and devices, applying its data-driven attribution model by default. This difference means that while both platforms report conversions, the numbers and underlying attribution logic can vary, providing a more holistic view when combined. Engagement, ROAS, and ROI are generally calculated based on underlying conversion data and costs, making them derivative metrics that reflect the differences in conversion tracking rather than being inherently different metrics themselves.
