## Resource

Lucas and Luna dive into a little-known Amazon PPC pitfall: bid stacking. When you layer a bid adjustment, a placement multiplier, and a dynamic bid strategy on the same keyword, the math doesn't always work in your favor. Lucas walks through a concrete example: a $1.00 base bid with a 50% top-of-search multiplier and a dynamic bid 'up only' setting can result in a $3.00 effective bid — and that's before considering performance-based modifiers. They discuss how brand advertisers and third-party sellers alike fall into this trap, why Amazon's own documentation is unclear on the stacking order, and a simple three-step audit to check your own campaigns. The episode includes a fresh angle not covered in previous 45 episodes: the interaction between bid multipliers at the campaign, ad group, keyword, and placement levels. #AmazonPPC #BidStacking #PaidAds #ROAS #AdvertisingStrategy #Ecommerce #Marketing #FexingoBusiness #BusinessPodcast #PPCMistakes #BidManagement #AmazonAds #SellerTips #AdOptimization #DigitalMarketing #PerformanceMarketing #SearchAds #CampaignAudit Keep every episode free: buymeacoffee.com/fexingo
