Comparative Advertising
Advertising that compares a product or service with competitors, subject to truthfulness requirements and platform-specific rules.
What Comparative Advertising means
Comparative advertising directly or indirectly references competitors' products or services to highlight differences or assert superiority. In the US, the FTC and Lanham Act permit comparative advertising when claims are truthful, substantiated, and not misleading. The EU Comparative Advertising Directive allows it under similar conditions. Platform policies vary — most allow comparative advertising if claims are factual and substantiated, but restrict negative comparative ads that denigrate competitors without evidence. Google allows competitor keyword targeting but restricts trademark use in ad copy (subject to trademark owner complaints). Common compliance issues include unsubstantiated superiority claims, misleading comparisons (comparing different product tiers), using outdated competitor data, and trademark infringement. Comparative claims carry heightened legal risk because competitors are likely to notice and may pursue legal action under trademark or unfair competition laws.
