# Overview

> Track feature flag exposure in FlagSync to measure flag variant impact.

## What Are Impressions?

Impressions record which flag variant a user sees—e.g., "Join Now" or "10% discount". They serve as the foundation for measuring feature impact in [Metrics](/metrics/overview) and [Experiments](/experiments/overview).

## Why Impressions Matter

  </Card>

  <Card title="Experiments" icon="flask">
    Enable variant comparison—e.g., does "Sign Up" outperform "Register"?
  </Card>

  <Card title="Insights" icon="lightbulb">
    Provide exposure data for debugging or rollout validation.
