Customer Engagement
27,561 of the 1,000,000 top sites in our Tranco top-1M census run WhatsApp Business (click-to-chat) (2.8%). A click-to-chat link or button that opens a WhatsApp conversation with the business directly. Detection is homepage-level HTML/header fingerprinting, so a site can run WhatsApp Business (click-to-chat) on other pages without it showing here.
