This method involves tracking user interactions through JavaScript in the user's browser, offering quick deployment but with potential reliability issues due to ad blockers and other browser restrictions.

This method tracks user interactions by executing JavaScript in the user's browser. This is easier to implement but relies on browser-based tracking (cookies, scripts). You can opt for this when you require a quick deployment or when server-side tracking is not feasible. However, its reliability can be affected by factors such as ad blockers, disabled JavaScript, or cookie restrictions, which may prevent tracking data from being collected accurately.
