You work for a media agency and are looking to optimise your client's responsive display ads to boost performance. Which of the following actions should you take to start?

Reviewing the asset report labels is the correct first step because it provides actionable insights into which assets are performing well ("Best," "Good") and which are underperforming ("Low"). This data-driven approach allows you to understand the current state of your responsive display ads and identify specific areas for improvement before making changes. Pausing the campaign would halt all ad delivery, losing potential impressions and conversions. Duplicating the campaign without prior analysis is inefficient and doesn't address current performance issues. Adding new assets without understanding existing asset performance is a shot in the dark and might not lead to optimization.
