# Concepts Overview

> The core ideas behind SignalBridge

SignalBridge exists to make conversion tracking reliable again in a world of ad blockers and privacy restrictions.

<Note>
  With the death of third-party cookies and rise of ad blockers, server-side tracking is no longer optional—it's essential for accurate data.
</Note>

## The Problem

Traditional browser-side tracking (Pixels) is failing:

    Prevent tracking scripts from loading for \~40% of users.

  <Card title="iOS Privacy" icon="apple">
    Limits cookie lifespan and blocks cross-site tracking.

    Pollutes your data and wastes ad spend on fake clicks.

## The Solution

SignalBridge captures events on your site and forwards them **server-side** to your ad platforms, ensuring:

* **100% Data Accuracy:** Bypasses ad blockers via your custom domain.
* **Better Attribution:** Server-side events match users more effectively.
* **Clean Data:** Automatic bot filtering removes junk traffic.
