If you're looking to boost performance by optimizing responsive display ads, which of the following actions should you take first?

Reviewing the asset report labels is the crucial first step because it provides data-driven insights into which creative assets are performing well and which are underperforming. This allows you to make informed decisions about what to optimize. Adding new assets without this review is a shot in the dark; you wouldn't know what types of assets are needed. Pausing or duplicating the campaign are drastic actions that don't address the underlying creative performance issues and would disrupt your ad delivery unnecessarily. The asset report guides your optimization efforts effectively.
