# Building your first goal

> Create a goal and attach it to a campaign

Goals are created and managed in the Loops dashboard. This guide walks through creating a goal and attaching it to a campaign. For the concepts behind eligibility, targets, and measurement windows, see the [Goals overview](https://loops.so/docs/goals/overview.md).

## Creating a goal

**1. Navigate to Goals**

Go to [Settings -> Goals](https://app.loops.so/settings?page=goals).

**2. Create a new goal**

Click **Create a goal** and give it a name. You can also add an optional description.

**3. Set the eligibility filter (optional)**

Use the filter builder to define which contacts are eligible to be enrolled. Leave it empty or toggle off the **Eligibility** section to make every contact who receives the campaign eligible.

**4. Set the target filter**

Use the filter builder in the **Conversion** section to define what success looks like, i.e. the contact state that should be considered as a conversion.

**5. Set the default measurement window**

Choose how many days contacts have to match the target filter after receiving a campaign.

## Attaching a goal to a campaign

**1. Open a draft campaign**

Goals can only be attached to campaigns that are still in **Draft**. Once a campaign has been sent or scheduled, its goal attachments are locked.

**2. Attach a goal**

In the campaign's **Send** page, select a goal from the goal picker.

**3. (Optional) Override the measurement window**

On the attachment, you can set a campaign-specific number of days.

**4. Send the campaign**

Contacts are evaluated for enrollment as the campaign delivers.

> [!WARNING]
>
> **Goals cannot be attached retroactively.** Attach and detach only work on draft campaigns. Once a campaign is sending or sent, its goal attachments are fixed.

Goals are reusable: the same goal can be attached to multiple campaigns.

Once your campaign is sending, head to [Understanding metrics](https://loops.so/docs/goals/metrics.md) to read the results.
