Which two variables can be used to optimize the rotation of dynamic creatives? (select two)

Click-through rate (CTR) and click-through-conversion rate are two key variables for optimizing dynamic creative rotation. CTR measures how often users click on an ad after seeing it, indicating initial engagement with the creative. A higher CTR suggests the creative is compelling. Click-through-conversion rate measures how often users convert after clicking on an ad, reflecting the creative's effectiveness in driving desired actions (e.g., purchases, sign-ups). Optimizing for both ensures that creatives not only attract clicks but also lead to valuable outcomes. Designated weights can influence rotation but are not performance metrics for optimization. Impression-to-view rate is a metric for viewability, not directly for creative performance optimization in terms of clicks or conversions.
