What does the tracker scanner detect?

The tracker scanner analyses any website and identifies all tracking scripts, pixels, and analytics tools — including Google Analytics, Facebook Pixel, TikTok Pixel, and advertising trackers.

Why do websites have so many trackers?

Most commercial websites use multiple third-party trackers for advertising, analytics, and retargeting. A typical news site may run 10-20 trackers simultaneously without users realising.

Is the tracker scanner free?

Yes — completely free, no signup required. Enter any URL to see every tracker running on that page instantly.

What is a tracking pixel?+

A tracking pixel (also called a web beacon) is a tiny 1×1 pixel image or invisible script embedded in a webpage. When you load the page, the pixel fires a request to the tracker's server, recording your visit, browser fingerprint, IP address and behaviour — even if you have never interacted with that site before.

What is the Facebook Pixel?+

The Facebook Pixel is a snippet of JavaScript code that loads on websites and sends data about your visits back to Facebook/Meta. It is used to build advertising audiences and measure ad conversions. It is present on an estimated 30–40% of all websites.

Can I block trackers?+

Yes — browser extensions like uBlock Origin, Privacy Badger and Ghostery block most trackers. Firefox has Enhanced Tracking Protection built in. Brave browser blocks trackers by default. Using a VPN or DNS-level blocking (like NextDNS or Pi-hole) adds another layer.

How accurate is this scanner?+

The scanner fetches the page HTML via our server and analyses it against 50+ known tracker signatures. It catches trackers loaded in the initial HTML. Some trackers — and cookie consent banners — load via JavaScript after page render and may not appear in the static source. A clean result means no trackers were found in the initial HTML, not that the page is tracker-free after full render.

What are Web Trackers?

Web trackers are scripts embedded in a page — from analytics platforms, ad networks, or social media widgets — that follow a visitor’s behavior across that site and often across other sites too, building a profile used for advertising or analytics.

Types of Tracking Technologies

Trackers commonly use third-party cookies, browser fingerprinting (identifying a device by its unique combination of settings rather than a stored cookie), and pixel tags (tiny invisible images that report back when loaded) — modern tracking increasingly relies on fingerprinting as browsers restrict third-party cookies.

How to Block Trackers

Browser extensions like uBlock Origin block known tracker domains outright; privacy-focused browsers block third-party cookies and reduce fingerprinting surface by default; and this scanner helps you see exactly which trackers a given page is running before deciding what to block.
