Client-side tracking involves collecting user data directly in the browser through tracking scripts. This method relies on third-party cookies to track user actions on websites.

It works by embedding tracking scripts into a website’s front-end, which sends data back to the servers. However, this approach faces challenges due to privacy restrictions like Intelligent Tracking Prevention (ITP) and Google’s Privacy Sandbox.While effective, it may be limited by users’ privacy settings, which block cookies or scripts.

The increase in privacy-first standards and data protection laws like GDPR has encouraged businesses to consider alternatives to client-side tracking. Still, it is widely used in analytics and marketing efforts to track user behavior, preferences, and conversions.
