# Update Audience Signals

> Add or remove audience signals on Performance Max and Demand Gen campaigns

Add or remove audience signals on Performance Max and Demand Gen campaigns. PMax uses AssetGroupSignal (one audience and optional search themes per asset group). Demand Gen uses ad-group audience criteria (one audience per ad group). Use the `gads_list_audience_segments` node with segment\_type='AUDIENCE' to find reusable audience signal IDs.
