This article explains how to create Custom Audiences in BidTheatre. It will provide a brief overview of all target types and explain how to work with the following conditions:

Go to Supply —> Audiences —> New Audience. Start by giving your Audience a name, then select the advertiser for whom the audience is intended.
​
​

​Fixed CPM – To use a custom audience, you need to assign it a price to ensure that the cost is included in the campaign’s Max CPM and budget. Select 'Automatic' to let the platform set this automatically based on the audiences you select. Choose 'Manual' if you prefer to set a custom price (most often used when audiences are sold to other seats).

Note: If Fixed CPM is left blank, the cost of using the audience will not be deducted from the campaign budget but will instead appear as an additional charge on the invoice.

Limit to country – If you want to restrict the audience to a specific country, you can select it here. Otherwise, leave this field blank.
​
​

After clicking "Create", you will see this view appear, with several target options. In this article, we will primarily focus on the target type 'User - Audience' to explain how to combine and exclude different types of existing 3rd Party Audiences. However, the same principles for using OR, AND, and NOT apply to all target types. At the end of this article, you will find a brief explanation of all target types.
​

Work with OR to create an audience composed of multiple different audiences. This way, you can add several different audiences to expand the total audience size.

Select 'User - Audiences,' click on the 'Value' field and search for the desired audience. Ideally, by this step, you have already explored 3rd Party Audiences (Supply → 3rd Party Audiences) and identified which audiences you want to add. Find your audience and add it by clicking the “Create” button:

Continue adding all the target audiences you wish to include in your custom audience. The order in which audiences are added is also the order in which the system will attempt to bid. This means the system will first try to find users in the top audience. If no match is found during the bidding process, it will then proceed to the next audience, and so on. You can adjust the order by dragging the target audiences up or down.
​

​
Your audience is now complete and ready to be used in your campaigns!

Use AND to combine multiple audiences. This means the user must match all selected audiences in the combination for BidTheatre to place a bid.

For example, let's say you want to reach "Men who are interested in shopping". Start by adding an audience that includes men. Then, to combine this with the shopping interest audience, click the plus sign on the same row:
​

Now, add your second audience that you wish to combine and click the “Create” button to include it:
​

​Note: Keep in mind that combining audiences drastically reduces the overall audience size. Whenever possible, use larger audiences to avoid overly narrow targeting.
​
​

Use 'NOT' to exclude a specific audience that you do not want to reach. 'NOT' can be used either independently or in combination with other audiences.
​
To change to 'NOT', click on the 'OR' symbol:
