Audience insights is a report that provides non-ad-attributed metrics to help advertisers understand the halo effects from an advertising campaign.

The correct answer is False because audience insights reports do not specifically focus on non-ad-attributed metrics or the halo effects from an advertising campaign. Instead, audience insights typically provide data regarding the demographics, behaviors, and interests of an audience, allowing advertisers to better understand their target market. While these insights can inform campaign strategies, they do not specifically measure the indirect effects or incremental impact of advertising on sales or brand perception, which is what halo effects would imply. Therefore, the statement is incorrect, making "False" the accurate choice.
