<h1>Legal checklist for publishers using automated multi-channel ad products: data compliance, truthful claims, exclusions, tracking, and contracts</h1> Publisher describes use of an automated multi-channel ad product to lower CPC and boost conversions, emphasizing conversion tracking, creative assets, audience signals, exclusions and feed optimization. Legal considerations include ensuring compliant collection and processing of user data (consent, server-side/enhanced tracking, applicable data protection laws), truthful and non-misleading performance claims in marketing materials, adherence to local advertising rules for location-targeted ads, and proper handling of negative keyword/exclusion features to avoid unintended discrimination. Advertisers should document tracking accuracy, maintain transparency in disclosures, and manage contractual liability and scope of services with any agency partner.
