Why You Should Care About URL Trackers and How to Remove Them
When you share or click a link, chances are it contains tracking parameters hidden in the URL.
These URL trackers are little pieces of text (like utm_source or fbclid) that companies use to follow where you come from, what you click, and even which campaign or ad led you here.
While they are useful for marketers, they also raise important privacy concerns.
🔒 How URL Trackers Affect Your Privacy
- Revealing your browsing habits: Trackers show which site or app referred you.
- Cross-platform profiling: Advertisers link your activity across websites.
- Cluttered URLs: Long, unreadable links full of random parameters.
- Unwanted data sharing: Information is often sent to third parties without your consent.
In short: URL trackers are like invisible breadcrumbs you leave all over the internet.
