Usercentrics Smart Data Protector

Consent Autoblocker Test Page

This page deliberately loads a range of third-party resources: tracking scripts, CDN libraries, video and map embeds. Both test variants are built identically apart from the Usercentrics snippet in the head. Use the browser devtools network tab to compare which requests actually go out.

1. YouTube video (iframe embed)

Standard YouTube embed via youtube.com. A working autoblocker replaces the iframe with a placeholder before it loads, or strips its src attribute.

youtube.com/embed – standard
youtube-nocookie.com/embed – privacy-enhanced mode

2. Further iframe embeds

A Vimeo player and a Google Maps embed as additional blocking candidates.

player.vimeo.com
google.com/maps/embed

3. Embedded third-party scripts

These resources are embedded in the <head> or at the end of the <body> – some as a plain <script src> tag, others as an inline snippet that only injects its loader at runtime via createElement('script').

4. Runtime injection tests

Only after a click is another third-party script or YouTube iframe inserted into the DOM via JavaScript. This verifies whether the autoblocker still catches resources after the initial page load, typically through a MutationObserver.

5. Tracking pixels & third-party images

A counting pixel and an external image – typical content-blocking candidates.
