How many parameters or segments should an advertiser choose to create a customized audience for their Audience Deals campaign?

Advertisers can use as many segments as needed to define their target audience for Audience Deals campaigns. The platform allows for flexible audience creation, enabling granular targeting. However, it's crucial to avoid micro-segmentation, which occurs when an audience becomes too small due to an excessive number of restrictive parameters. Micro-segmentation can lead to limited reach, higher CPMs, and difficulty in campaign delivery and optimization. Therefore, while flexibility exists, a balance must be struck to ensure the audience is both relevant and of sufficient size. Choosing a fixed number of segments (one, two, or three) is too restrictive and doesn't account for the diverse targeting needs of different campaigns.
