# Expected EMQ Increase: Projected Score Improvement

> Track predicted EMQ score gains from fixing specific match key issues. Prioritize data quality fixes by their potential impact on Meta event matching.

<Tip>
  Expected EMQ Increase shows how many EMQ score points you would gain by fixing a specific match key issue.
</Tip>

## Formula

<Info>
  **Expected EMQ Increase** = Predicted [**EMQ Score**](/reference/metrics/data-quality/emq/emq-score) improvement from resolving the [**Match Key Coverage**](/reference/metrics/data-quality/emq/match-key-coverage) issue
</Info>

### Formula Components

| Metric                                                                           | Definition                                             |
| -------------------------------------------------------------------------------- | ------------------------------------------------------ |
| [**EMQ Score**](/reference/metrics/data-quality/emq/emq-score)                   | Your existing Event Match Quality score (0-10)         |
| [**Match Key Coverage**](/reference/metrics/data-quality/emq/match-key-coverage) | Current coverage percentage for the specific match key |

| Metadata        |                                   |
| --------------- | --------------------------------- |
| **Type**        | Number                            |
| **Data Source** | [Meta Ads](/sources/facebook-ads) |
| **Aggregation** | Prediction                        |
| **Format**      | +X.XX                             |

***

## Example

Your **email match key** has 45% coverage and is flagged as an issue. The Expected EMQ Increase shows **+1.25 points**.

| Match Key   | Current Coverage | Expected EMQ Increase | Priority |
| ----------- | ---------------- | --------------------- | -------- |
| Email       | 45%              | +1.25                 | High     |
| Phone       | 62%              | +0.78                 | Medium   |
| External ID | 28%              | +0.42                 | Low      |

## How It Works

Meta calculates the predicted score improvement based on your current EMQ score, the specific match key's coverage gap, and historical matching patterns. Higher predicted increases indicate match keys with greater potential to improve your overall event quality.

## When to Use

| Scenario            | Action                                                  |
| ------------------- | ------------------------------------------------------- |
| Prioritizing fixes  | Address match keys with highest expected increase first |
| Resource allocation | Focus engineering effort on highest-impact improvements |
| Reporting progress  | Track cumulative potential gains as issues are resolved |
| Setting targets     | Use predictions to set realistic EMQ improvement goals  |
