The ad group builder allows you to create custom ad groups by clicking the "new ad group" button, then selecting "create your own". You'll enter an ad group name, optionally provide a URL (such as a specific service page from your website), and can add a focus area description. After generating the ad group, you can review the destination path in the destination accordion before proceeding. The builder validates that URLs and focus areas work together logically to produce relevant content.
Note: The focus area and URL must be related—for example, you cannot use a pet shop URL with an escape room focus area, as there needs to be a logical connection between them for the AI to generate relevant content.
