What are the three main elements that make up brand safety on Reddit?

Brand safety on Reddit is built upon three core elements: communities, content, and campaign controls. Communities are central to Reddit, and advertisers can choose to target or exclude specific subreddits to align with their brand values. Content refers to the actual posts and comments within these communities, which Reddit moderates to enforce platform-wide policies against hate speech, harassment, and other harmful material. Finally, campaign controls give advertisers direct tools to manage where their ads appear, including keyword targeting/exclusion and inventory filters, ensuring their ads are shown in brand-suitable environments. The other options describe aspects of Reddit's platform or ad ecosystem but are not the primary pillars of brand safety.
