Big Tech tracking is way bigger than just cookies.

Google, Meta, and Amazon collect data from your browsing history, clicks, searches, location, and even the invisible scripts embedded across websites, then use it to build detailed profiles for targeted ads.

In this video, we break down exactly how online tracking works, step-by-step:
• Tracking cookies and third-party cookies
• Pixels, scripts, and embedded widgets 
• Browser fingerprinting (Canvas, WebGL, Audio APIs)
• Device tracking and cross-device identity linking
• Why trackers still work even when you block cookies

Then we switch to the most important part: how to reduce tracking in real life. You cannot become 100% invisible online, but you can make tracking dramatically harder.

Big tech companies like Google, Meta, and Amazon track users through cookies, browser fingerprinting, device identifiers, and embedded widgets across websites. Cookies store unique IDs to follow browsing history, while fingerprinting uses device characteristics like screen resolution, fonts, and canvas rendering to create unique identifiers without storing data. Third-party trackers appear on most websites through social buttons, analytics, and advertising networks. Users can protect themselves by blocking third-party cookies, using privacy-focused browsers like Brave or Firefox, installing tracker-blocking extensions like uBlock Origin, enabling VPNs, and adjusting privacy settings on major platforms.
