How Online Tracking Works
Companies use multiple methods to track your online behavior.
TL;DR: Tracking happens through cookies, fingerprinting, IP address, and cross-site tracking. Understanding these helps you protect yourself.
Tracking Methods
1. Cookies
- Small files stored in browser
- Track sessions and preferences
- First-party vs third-party
- Can be cleared but reappear
2. Browser Fingerprinting
- Device and browser characteristics
- Unique identifier without cookies
- Hard to prevent completely
- See our fingerprinting guide
3. IP Address Tracking
- Geographic location
- ISP information
- Session correlation
- Blocked with proxies/VPNs
4. Cross-Site Tracking
- Third-party scripts on multiple sites
- Advertising networks
- Social media buttons
- Analytics services
5. Local Storage
- More persistent than cookies
- IndexedDB, localStorage
- Often overlooked
Who's Tracking You
- Advertising networks (Google, Facebook)
- Data brokers
- Analytics companies
- Social media platforms
- Your own ISP
Protection Measures
- Use proxies for business activities
- Clear cookies regularly
- Use private browsing when appropriate
- Block trackers with extensions
- Minimize social logins across sites
Proxies help hide your IP but aren't complete tracking protection. Combine with other measures for comprehensive privacy.
