The policies and controls used to reduce the risk that advertising appears beside content or in contexts that could harm a brand.

Ads that appear next to harmful or misleading content can damage reputation and trust, so brand safety controls protect the brand while balancing reach and cost.

A financial services advertiser excludes sensitive content categories in Google Ads, applies a list of 2,000 blocked YouTube channels and uses a verification vendor that reports the share of impressions flagged as unsafe each week.

Broad keyword blocklists can block legitimate news and reduce reach while raising CPMs. Classification of video, user-generated and live content is imperfect, and brand safety settings do not guarantee that every placement fits the brand.

Controls work at several levels: platform settings such as inventory type and content exclusions, keyword and URL blocklists or allowlists, contextual classification using taxonomies like the IAB Tech Lab Content Taxonomy, and pre-bid and post-bid verification. Industry frameworks separate a floor of content no advertiser should fund from a brand-specific suitability tier.
