A/B Testing & Personalization
411 of the 1,000,000 top sites in our Tranco top-1M census run Salesforce Collect (Marketing Cloud) (0%). A Salesforce Marketing Cloud tag that collects on-site visitor behavior data for personalization and analytics. Detection is homepage-level HTML/header fingerprinting, so a site can run Salesforce Collect (Marketing Cloud) on other pages without it showing here.
