A/B Testing & Personalization
1,498 of the 1,000,000 top sites in our Tranco top-1M census run Google Optimize (0.1%). A discontinued Google website A/B testing and personalization tool that let teams run experiments and target content variants to visitors. Detection is homepage-level HTML/header fingerprinting, so a site can run Google Optimize on other pages without it showing here.
