Which feature could help a retailer ensure that their Search ads accurately reflect details about their company's annual sale?

The Countdown customizer is the most effective feature for a retailer to highlight an annual sale because it dynamically updates the ad copy with a real-time countdown to a specific event, like the end of a sale. This creates urgency and ensures the ad always shows the most current time remaining. Location insertion personalizes ads based on the user's location, which isn't relevant to a sale's timing. Keyword insertion dynamically updates ad text with keywords from the user's search query, which also doesn't address the sale's duration. Dynamic customizer is a broader term that includes countdowns, but "Countdown customizer" is the specific feature for this use case.
