A/B Testing & Personalization
538 of the 1,000,000 top sites in our Tranco top-1M census run Dynamic Yield (0.1%). An ecommerce personalization and A/B-testing platform (Mastercard's). Detection is homepage-level HTML/header fingerprinting, so a site can run Dynamic Yield on other pages without it showing here.
