Have you looked at your products and determined their true profitability? Not the gross revenue each one generates — but the actual net profit after COGS, platform fees, fulfillment, advertising, and returns?

Most sellers haven’t. They know their bestsellers by volume. They rarely know their bestsellers by profit. Those two lists are often very different. Your most profitable product might be your third or fourth bestseller. And your #1 seller might be breaking even or losing money once all costs are accounted for. Know the difference. Build your inventory and ad strategy around profit, not volume.
