¿Qué significa que las métricas de Display Catalog Ads se muestran por line item?

Display Catalog Ads metrics shown by line item means that each ad set has its own performance data. This allows advertisers to independently analyze the effectiveness of different advertising tactics. By centralizing results at the line item level, it's possible to precisely identify which targeting, audience, or bidding strategy is delivering the best return indicators. This facilitates granular optimization, enabling budgetary and strategic adjustments without mixing information from different ad groups within the campaign. The other options are incorrect because "each ad has its separate metrics" is too granular, as line items group multiple ads, and "each ad shows a single product" describes a characteristic of the ad content, not how metrics are organized.
