Summary
Episode 115 of Performance Marketing with Fexingo dives into a blind spot that silently shreds your Amazon PPC ROAS: failing to split-test ad copy within campaigns. Lucas and Luna walk through a real-world example from March 2026 where a seller running a single ad group for 'cordless vacuum' saw their click-through rate drop from 8% to 3% over four weeks. The culprit? A stale headline that got out-performed by a competitor's new angle. They discuss how to set up AB tests using campaign name tags, the minimum data window for statistical significance (2,000 impressions per variant), and how to automate the kill-or-scale decision with simple rules in the new Amazon Ads API v4. By the end, you'll know exactly how to identify copy fatigue before it drags down your blended ACOS. #AmazonPPC #AdCopy #SplitTest #ROAS #ACOS #PerformanceMarketing #Fexingo #PaidAds #DirectResponse #ABTesting #AmazonAdsAPI #ClickThroughRate #CampaignOptimization #CopyFatigue #MarketingBlindSpot #FexingoBusiness #BusinessPodcast #MarketingPodcast Keep every episode free: buymeacoffee.com/fexingo
