What deters advertisers from showing ads on a video?

Explicit language is a common factor that deters advertisers. Brands generally want their advertisements to appear alongside content that aligns with a positive and family-friendly image. Content containing explicit language can be flagged by automated systems or human reviewers as brand-unsafe, leading advertisers to avoid placing ads on such videos to protect their brand reputation. Parodies, niche topics, and collaborations are generally not deterrents. Parodies are a form of creative content, niche topics can attract highly engaged audiences, and collaborations are a standard way creators work together; none inherently violate brand safety guidelines.
