What Is Bounce Tracking and How It Replaces Traditional Cookies

Bounce tracking, also called redirect tracking, is a way to follow people across websites without third-party cookies. When you click a link, you pass through a tracker's website for a split second before landing where you meant to go. You rarely notice.
How it works
- You click a link on site A that points to site B.
- The link actually goes to tracker.example first.
- Because you visited tracker.example directly, even briefly, its cookies count as first-party. It reads or sets an ID for you.
- It instantly redirects you to site B, often adding an ID to the address.
Repeated across many sites, the tracker builds a picture of where you go.
Why it matters now
Browsers block or limit third-party cookies, the classic way to track across sites. Bounce tracking doesn't replace cookies so much as get around those limits: it uses first-party cookies by making you visit the tracker for a moment. It often works alongside link decoration, where IDs are added to URLs. See link decoration explained.
Not every redirect is tracking
Redirects are also used for sign-in, payment pages and email click counting. The privacy problem is when a third party uses the bounce to recognize you across unrelated sites.
How browsers fight it
- Safari: Intelligent Tracking Prevention detects sites used as bounce trackers and deletes their stored data.
- Firefox: Enhanced Tracking Protection regularly clears cookies and site data from known trackers you haven't used directly.
- Brave: "debouncing" skips known tracking redirects and takes you straight to the destination.
- Chrome: has added bounce tracking protections that clear stored data for sites that act like bounce trackers, for people who block third-party cookies.
What you can do
- Block third-party cookies. In Chrome: Settings → Privacy and security → Third-party cookies.
- Clear cookies regularly, or set the browser to clear them when you close it.
- Use a content blocker with tracker lists, which stops many tracking domains from loading.
- Check links before clicking: hover to see where a link really goes, and remove long tracking strings from URLs you share.
- Consider a browser with stronger defaults if privacy matters most to you.

Ghost Browser takes a different approach: it makes random background visits to blur your browsing profile. It doesn't block redirects, so pair it with the settings above.
