# Meta Subscribes: Subscription Sign-ups from Ads

> Track subscription sign-ups attributed to your Meta ads. Measure how effectively your campaigns drive recurring revenue for SaaS and subscription businesses.

<Tip>
  Meta Subscribes counts how many subscription sign-ups your Meta ads generated during the selected period.
</Tip>

## Formula

<Info>
  **Meta Subscribes** = **COUNT** ( Subscribe Events )

  Each subscription event triggered by Meta ad engagement is counted once.
</Info>

| Metadata        |                                   |
| --------------- | --------------------------------- |
| **Type**        | Number                            |
| **Data Source** | [Meta Ads](/sources/facebook-ads) |
| **Aggregation** | Count                             |

***

## Example

Your SaaS product acquired **127 new subscribers** from Meta campaigns this quarter.

| Campaign           | Subscribes | Cost per Subscribe |
| ------------------ | ---------- | ------------------ |
| Retargeting        | 52         | \$18.50            |
| Lookalike Audience | 45         | \$24.20            |
| Interest Targeting | 30         | \$31.80            |

## How It Works

Meta tracks subscription events when users complete a subscribe action after engaging with your ad. This requires the Meta Pixel or Conversions API to fire a Subscribe event. Attribution follows your configured window (typically 7-day click, 1-day view).
