Your client has very specific brand guidelines, so you need to help them set up universal brand controls across all products. Within the Display & Video 360 account settings hierarchy, what's the highest level you should use?

The highest level for setting universal brand controls in Display & Video 360 is the Partner and Advertiser level. Brand controls, such as brand safety settings, content exclusions, and viewability thresholds, are typically applied at these higher levels to ensure consistent application across all campaigns and line items within that advertiser or partner. Applying them at the Partner level ensures they apply to all advertisers under that partner, while applying them at the Advertiser level ensures they apply to all campaigns and line items under that specific advertiser. Insertion order & Campaign and Line item & Campaign are too granular. Settings at these levels would need to be manually duplicated across many different entities, making it difficult to maintain universal control and increasing the risk of inconsistencies. Campaign & Partner is incorrect because "Campaign" is a lower level than "Advertiser" in the hierarchy for applying universal controls.
