A brand wants to avoid showing ads on videos that include moderate profanity, which is otherwise allowed for monetization. Which control should they use?

They need brand suitability controls. It is worth separating two ideas that sound alike. Brand safety is the platform-wide floor: content that breaches Google's policies cannot be monetised and ads do not appear on it at all. Brand suitability sits above that floor and is specific to each advertiser — content that is perfectly allowed to carry ads may still be wrong for a particular brand. Moderate profanity is the textbook case: it is permitted for monetisation, so brand safety does not exclude it, but a family brand may want nothing to do with it. Suitability controls let advertisers apply inventory modes, exclude sensitive content categories and specific types of content, and block individual placements, tightening standards without waiting for the platform to change its policies.
