Google Ads AI Disclosure & TikTok Ads: 2026 Policy Shake-Up for Advertisers

The key change in 2026 is that Google Ads now mandates disclosure labels for ads created or edited with generative AI, placing full legal liability on advertisers. This policy, effective July 2026, coincides with TikTok brands like SharkNinja warning creators against using AI video tools. Meanwhile, the rise of agentic commerce is squeezing traditional ad impressions on Google, forcing advertisers to adapt their data strategies across both platforms.

Google Ads AI Transparency Labels: What Advertisers Must Do

Starting in July 2026, Google Ads introduced a new transparency feature: a "How this ad was made" section in the My Ad Center panel. This label appears automatically when ads are created with Google's generative AI tools (e.g., Performance Max with AI-generated assets). For advertisers using third-party AI tools, disclosure is optional but encouraged—however, liability for accuracy rests entirely with the advertiser. According to Google's official blog, the roll-out covers Search, YouTube, and Google Discover. A Search Engine Journal article details that the EU AI Act's August 2, 2026 applicability date is a key driver, with penalties for non-compliance.

Liability Shift and the EU AI Act Context

A PPC Land analysis emphasizes that Google has transferred the legal burden of AI disclosure to advertisers. This means even if a third-party AI tool generated the ad, the advertiser is responsible for documenting its use. The EU AI Act imposes fines of up to 7% of global annual turnover for violations, making compliance critical for any advertiser targeting European audiences.

TikTok Brands Crack Down on AI-Generated Content

On the same week, major brands on TikTok are pushing back against AI-generated promotional content. An Independent report reveals that SharkNinja and other brands have warned their TikTok Shop affiliate creators about a "No AI-Generated Content policy," threatening to remove commissions if violations occur. This comes as AI video maker tools spread rapidly on TikTok, raising concerns about misrepresentation in product demos. TikTok itself allows AI content with disclosure, but brands want authenticity—creating a tension that advertisers must navigate.

Agentic Commerce Shrinks Google Ad Impressions

Beyond disclosure, a broader structural shift is reshaping digital advertising: agentic commerce, where AI agents handle purchasing decisions on behalf of consumers. A Search Engine Journal piece explains that these agents are reducing ad impressions on Google because they bypass traditional search ads, instead directly making purchase decisions based on product data feeds. For advertisers, this means clean, standardized product data, bot access, and protocol readiness (e.g., UCP) are now essential to remain visible in AI-generated "shortlists." Advertisers using TikTok Ads must also ensure their product catalogs are machine-readable, as TikTok's commerce ecosystem may face similar agentic shifts.

Google Ads Policy Expansions for Alcohol, Gambling, and Games

On July 14, 2026, Google announced expansions to its alcohol, gambling, and games advertising policies. Effective July 28, alcohol ads will be allowed in 29 additional countries, including Brazil, Kenya, South Korea, and Vietnam, with ABV limits varying by region. Gambling and games certification requirements will be updated starting September 14, 2026. A Google support page provides the official list of new countries, while Seroundtable explains the compliance implications. Advertisers running campaigns on both Google and TikTok must adjust their targeting to comply with these new rules, especially in regulated verticals.

Comparison: Google Ads vs. TikTok Ads on AI and Policy

Aspect	Google Ads	TikTok Ads (via Brands)
AI disclosure required	Yes, mandatory for Google AI tools; optional for third-party but liability on advertiser	Brands like SharkNinja ban AI content entirely; TikTok allows with disclosure
Liability for AI	Advertiser bears legal risk under EU AI Act	Brands enforce via commissions and terms
Product data needs	Clean, structured data for agentic commerce visibility	Authentic creator content preferred; AI clones discouraged
Recent policy changes	Alcohol/gambling expansion; AI labeling; agentic commerce	Brands urging creators to ditch AI fakes
Target audience	Search and Discover users	TikTok Shop shoppers and FYP users

Practical Implications for Cross-Platform Advertisers

Advertisers running campaigns on both Google and TikTok must adapt to two diverging policy environments. On Google, the priority is transparency: implement internal documentation of AI use in ad creation, ensure product feeds are agent-friendly, and stay updated on policy expansions for restricted categories. On TikTok, the focus is authenticity: avoid AI-generated promotional content unless strictly disclosed and compliant with brand guidelines. With agentic commerce rising, investing in clean product data and protocol readiness (e.g., Google's UCP) will pay off on both platforms by making ads eligible for AI-driven shortlists.

The Role of Third-Party AI Tools

Many advertisers rely on third-party AI tools for ad creative, from text generation to video production. Under Google's new rules, these advertisers must manually indicate AI usage. Failure to do so could result in ads being removed or accounts suspended. The TechCrunch article notes that while Google's disclosure is automatic for its own tools, the onus is on advertisers for external tools. This is especially relevant for TikTok, where AI video makers are popular. Brands like SharkNinja are already banning such tools, so advertisers should verify their compliance tools and workflows.

Conclusion

The 2026 landscape for Google Ads and TikTok Ads is defined by a push for transparency and authenticity. Google's AI disclosure labels, agentic commerce trends, and policy expansions demand careful attention from advertisers. Simultaneously, TikTok brands are asserting control over AI-generated content. Advertisers who proactively update their data hygiene, disclosure practices, and creative strategies will be best positioned to succeed across both platforms.
