How a Single Button Color Test Cost a SaaS Company 40 Percent Revenue

Episode 51 of Conversion Rate Optimization with Fexingo dives into a cautionary tale: how a SaaS company lost 40% of its trial-to-paid conversion by testing button color—without controlling for user intent. Lucas and Luna unpack the difference between surface-level A/B tests and meaningful behavioral experiments, explaining why the same button color can double or halve conversion depending on whether the visitor is in 'research' or 'ready-to-buy' mode. They walk through the methodology: segmenting by traffic source, measuring time-on-page as a proxy for intent, and analyzing the interaction effect between button color and user stage. The episode also touches on how novelty effects can mask these flaws, and why a 12-variant test without segmentation is just noise. By the end, listeners learn a concrete framework: never test a surface element without first splitting by intent signal.
