# Audience
Audiences let you create your own lists of users to use in your advertising campaigns. This feature helps you control exactly who sees (or doesn’t see) your ads. Below is a detailed description how it works.
Two audience targeting options are available:
* **Exclude Audience** - exclude selected users from seeing your ads.\
This is useful if you want to avoid showing ads to users who have already taken certain actions or already belong to your existing customer base.
* **Target Audience** - show ads only to the users in a selected audience.\
This is useful if you have a specific set of users you want to reach—perhaps because they match a customer profile or have interest in a similar product. This targeting can also be useful if you want to show ads to users who have blocked your application. To do this, create a list of such an audience and use it in this parameter.
**Cost:** сurrently, there is no additional charge for target audience campaigns.
## **1. Create a new Audience**
Go to the Audience section and click "Create Audience**"**. In the pop-up window, enter a name for your audience to identify it and click "Create".
## **2. Upload users to Audience**
After creating the audience, click "Upload users". Select and upload one or more CSV files containing your user lists.
**File requirements:**
* **File format:** must be in CSV format
* **Required Column:** a column named **`telegram_id`**
Every value in `telegram_id` must be an integer (e.g., `12345`). Invalid values will be skipped and will not be added to the database
{% hint style="info" %}
You can create multiple audience groups for different purposes — for instance, one for users who made a purchase, another for users who only signed up but never purchased, etc.
Also you can add more users later by uploading additional CSVs to the same audience (useful if you get new user lists over time). The data from each CSV will combine with previously uploaded data.
{% endhint %}
## **3. Use Audience in your Ad campaigns**
Once an audience is created and user data is uploaded, you can select that audience during [Ad creation or editing](https://tads.gitbook.io/docs/getting-started/advertisers/ad-targeting/pages/qFZsNSOeR9D2B1j9dWFm#id-5.-exclude-or-target-audience)
