# Building an audience

On the **Audience** tab, build your audience by including and excluding characteristics, also known as variables. For example, you might include your high value customers but exclude anyone who's recently made a purchase or opted out of communication.

Click **Add Filter** to build up sections of your audience and choose how their characteristics combine.

## Choosing a table level

Decide what you're trying to count, such as *people* or *transactions*, then use the drop-down menu at the top of the display to select the table level for your audience:

> [!NOTE]
>
> Your administrator sets a system default table level. On Apteco's Holidays system, this is People.

## Naming your audience

Orbit gives your new audience a default name. Click the name and type over it to give it your own description.

You can also rename an audience while it's open for editing: click the audience name, then click away or press **Enter** to confirm.

> [!NOTE]
>
> Orbit automatically saves any changes you make to an audience. The icon to the left of the audience name shows the current save status.

## Undo, redo, and reset

Use the Undo, Redo, and Reset options below the save icon to revert to a previous state, even though Orbit saves your changes automatically.

## Adding a campaign brief

Click **Show Brief** on the right of the audience window, then copy and paste your campaign brief into the Brief panel:

Leave the panel open for reference while you build your audience, or click **Hide Brief** to collapse it again.
