Garmend is forming a strategy for a new back-to-school campaign for children's clothing. Which of the following ASINs will likely perform best in terms of sales efficiency?

For a back-to-school campaign focused on sales efficiency, prioritizing best-selling ASINs ensures you're promoting products with a proven track record of demand and conversion. These items are already popular, making them more likely to generate sales with advertising. Combining these with retail-ready ASINs is crucial because retail-ready products have optimized listings (images, titles, bullet points, A+ Content) and sufficient inventory, which are essential for converting ad clicks into purchases. Products that are not retail-ready, even if best-selling, may underperform due to poor customer experience. New product ASINs, while important for long-term growth, typically require more effort and investment to gain traction and are less efficient for immediate sales generation in a campaign focused on efficiency.
