If the marketing site and application use different domains, transfer attribution through an approved server session or short-lived signed token rather than assuming browser storage will cross the boundary.<\/p>\n<h2>How do you build the Mixpanel conversion funnel?<\/h2>\n<p><strong>Build a unique-user, ordered funnel beginning with <code>AI Referral Landing<\/code> and ending with the conversion that represents real product intent.<\/strong> A trial-start funnel is more decision-useful than a pageview-to-signup report because it excludes registrations that never reach the product.<\/p>\n<p>Configure these steps:<\/p>\n<ol>\n<li><code>AI Referral Landing<\/code><\/li>\n<li><code>Signup Started<\/code><\/li>\n<li><code>Signup Completed<\/code><\/li>\n<li><code>Trial Started<\/code><\/li>\n<li>Optional: <code>Activated<\/code><\/li>\n<\/ol>\n<p>Use specific-order conversion and count unique users. Start with a window that reflects your normal signup cycle, then compare shorter and longer windows\u2014for example, one, seven, and 30 days\u2014to expose delayed conversions.<\/p>\n<p>Mixpanel notes that funnel results depend on counting method, conversion window, step ordering, exclusions, and constant properties.
