Qual dos seguintes métodos é adequado para melhorar a performance das campanhas de Product Ads?

Determining profitability levels, segmenting products, and creating multiple campaigns is the correct approach because it allows for granular control and optimized resource allocation. Understanding product profitability helps set appropriate ROAS targets. Segmenting products by categories or performance allows for tailored bidding strategies and budgets. Creating multiple campaigns ensures that different product groups receive customized attention, preventing high-performing products from being held back by low performers and maximizing overall campaign efficiency. The option suggesting a negative marginal contribution is incorrect because a negative contribution means losing money on sales, which is unsustainable. The option focusing solely on unit costs and a single campaign strategy is insufficient; it lacks the crucial elements of profitability analysis and product segmentation needed for effective optimization in Product Ads.
