¿Cómo se calcula el costo publicitario de ventas (ACOS)?

ACOS (Advertising Cost of Sales) is a key metric for evaluating the efficiency of advertising campaigns. It is calculated by dividing the total advertising spend by the total attributed sales generated from those ads. This formula, "inversión publicitaria/ventas atribuidas" (advertising spend / attributed sales), directly reflects the cost incurred for every dollar of sales earned through advertising. The option "inversión publicitaria por ventas atribuidas" (advertising spend multiplied by attributed sales) would result in a much larger, incorrect value that doesn't represent a cost-to-sales ratio. "Inversión publicitaria/clics" (advertising spend / clicks) and "inversión publicitaria por clics" (advertising spend multiplied by clicks) relate to cost per click (CPC) or total cost based on clicks, not the overall advertising efficiency relative to sales.
