Understanding the limitations of traditional A/B testing, Contentful highlights the advantages of multi-armed bandit (MAB) testing, an AI-powered approach that optimizes digital content experimentation by dynamically allocating resources based on real-time performance data. Unlike A/B testing, which evenly divides traffic between variants and requires a fixed schedule, MAB testing continuously adapts, directing more traffic to higher-performing variants, thereby accelerating the discovery of optimal content and maximizing audience engagement and conversion rates. This method, exemplified through scenarios like online retail promotions and media site headline testing, showcases its ability to enhance efficiency and effectiveness in content optimization. Contentful's platform incorporates both A/B and MAB testing tools, offering brands a comprehensive solution to automate testing strategies, define audiences, and analyze results within its headless CMS.
