Which of the following tools can help marketers maximise the performance of a value-based bidding strategy?

Target simulators are crucial for value-based bidding strategies because they allow marketers to forecast how changes to their target ROAS (Return on Ad Spend) or target CPA (Cost Per Acquisition) might impact performance metrics like conversions and conversion value. This predictive capability helps optimize bids to achieve specific business goals while maximizing value. Diagnostic insights provide general account health information but don't directly simulate bidding strategy changes. Keyword Planner assists with keyword research and bid estimates, not simulating value-based bidding outcomes. Ad strength rating evaluates ad copy quality, which is separate from bidding strategy simulation.
