Lucas and Luna uncover a pernicious Amazon PPC blind spot: failing to use negative product targeting ASINs in your Sponsored Products campaigns. Using a real-world example of a kitchen knife seller whose ads appeared on a $2.99 plastic peeler listing, they explain how this mistake inflates ad spend, drags down click-through rates, and distorts the campaign's relevance score. They walk through the simple diagnostic—pull the search term report, sort by spend without conversion, and identify the ASINs eating budget—and show how excluding those ASINs can immediately improve ROAS by 20-30 percent. This episode drills into the tactical fix that most sellers overlook because Amazon hides negative product targeting behind a menu toggle, not in the keyword negative targeting tab. Specific, actionable, and based on real campaign data.
