| -------------------------------------------------------------------------- | -------------------------------------------------- |
| [**Ad Spend**](/reference/metrics/advertising/blended/blended-spend)       | Total advertising cost from connected ad platforms |
| [**Demo Requested**](/reference/metrics/funnel/conversions/demo-requested) | Count of demo requests                             |

## Example

You spent **\$5,000** on LinkedIn ads in January and drove **94 demo requests**.

| Metric              | Value   | Notes                    |
| ------------------- | ------- | ------------------------ |
| Ad Spend            | \$5,000 | Monthly advertising cost |
| Demo Requested      | 94      | Demo submissions         |
| Demo Requested Cost | \$53.19 | Cost per demo lead       |

***

## How It Works

This metric divides your total ad spend by the number of demo requests. It represents your cost per lead (CPL) for the sales-led funnel.
