A/B Testing & Personalization
1,334 of the 1,000,000 top sites in our Tranco top-1M census run Convert (0.1%). An A/B testing and website personalization platform for running conversion-rate optimization experiments. Detection is homepage-level HTML/header fingerprinting, so a site can run Convert on other pages without it showing here.
