# Ad blocker bypass

> Why custom domains reclaim lost conversions

Ad blockers target known tracking domains and scripts. SignalBridge works by routing tracking through **your own domain**.

## The core idea

Instead of loading third-party trackers directly:

* `connect.facebook.net`
* `www.googletagmanager.com`

…you load a first-party tracking endpoint like:

* `tracking.yourbrand.com/pixel.js`

## What you gain

* Fewer blocked requests
* Better attribution coverage
* More complete platform optimization signals

## Setup

Follow the CNAME setup in [Quick Start](/quickstart).
