The script initializes a tracking session by generating or retrieving a unique identifier stored in browser cookies or localStorage
Event listeners are attached to DOM elements to capture user interactions including clicks, form submissions, scroll events, and page navigation
Collected behavioral data is batched and transmitted to the tracking company collection servers via asynchronous HTTP requests or beacon API calls
Server-side processing systems match incoming events against existing user profiles and update behavioral models used for targeting and analytics
