¿Qué estadísticas publicitarias muestran el porcentaje de ventas invertido en publicidad?

Costo publicitario de ventas (ACOS) is the correct answer because it directly measures the percentage of sales spent on advertising. It's calculated by dividing total ad spend by total sales generated from those ads. A lower ACOS indicates more efficient ad spending. Costo por clic (CPC) measures the cost incurred for each click on an ad, not the percentage of sales invested. Retorno de la inversión publicitaria (ROAS) is the inverse of ACOS, showing how much revenue is generated for every dollar spent on advertising, rather than the percentage of sales spent on ads.
