How Checking for Novelty Effects Saves Your A-B Tests

Lucas and Luna tackle a subtle but dangerous threat to A-B test validity: the novelty effect. Listeners learn how early spikes in conversion often mask users' initial curiosity rather than true preference change. The hosts walk through a real case from a mid-market SaaS company that saw a 6% lift on the first day of a test only to watch it evaporate by day seven. They explain how to spot the pattern, when to run a two-week minimum, and why segmenting by new vs. returning users can save you from shipping a losing variant. Packed with practical guardrails for any marketer running tests in 2026. #ABTesting #NoveltyEffect #ConversionRateOptimization #MarketingTips #DataDrivenMarketing #SaaS #LandingPage #UserBehavior #Statistics #TestValidity #FexingoBusiness #BusinessPodcast #MarketingPodcast #CROStrategy #ExperimentDesign #DigitalMarketing #LucasAndLuna #Fexingo Keep every episode free: buymeacoffee.com/fexingo
