The IAB has updated its recommendations on AI disclosure as advertising-related legislation continues to evolve.

The update reflects a straightforward operational problem for ad buyers and publishers: laws governing AI-generated content and AI-driven ad decisions are changing faster than most compliance workflows can track, and the IAB's guidance is the reference point many US publishers and advertisers use to stay on the right side of the rules.

What changed

The revised recommendations adjust how the industry body advises companies to disclose the use of artificial intelligence in advertising content and ad operations. Marketing Brew first reported the update.

The move signals that earlier guidance no longer matched the current regulatory environment. Lawmakers at federal and state level have introduced a stream of AI-related bills over the past two years, and several touch directly on advertising — from disclosure requirements for synthetic media to rules on AI-generated endorsements and synthetic voices.

** Why it matters for operators**

For publishers, the practical question is where and how to label AI-generated or AI-assisted content. For advertisers and agencies, it is what needs disclosing in creative production, targeting, and audience modelling. Ambiguity in either area creates legal exposure and, increasingly, audience trust problems.

Trade bodies like the IAB do not write law. Their recommendations carry weight because regulators and platforms often borrow from them, and because following industry-standard guidance is a defensible position when enforcement questions arise. An update from the IAB therefore tends to ripple into vendor contracts, publisher policies, and RFP language within months.

The legislative backdrop

The update lands amid an uneven patchwork of AI rules. The EU AI Act is phasing in obligations for synthetic content labelling. In the US, there is no single federal AI statute covering advertising, but state-level laws and Federal Trade Commission enforcement on deceptive practices already reach AI-generated ad content.

That unevenness is exactly why the IAB revisits its guidance. Companies operating across jurisdictions need a baseline disclosure standard that holds up under the strictest regime they touch, not fifty local variants.

What to watch

Expect further revisions. The IAB has updated its AI guidance more than once already, and each legislative development — a new state law, an FTC action, an EU implementing detail — tends to trigger adjustments.

Ad ops teams should treat this as a living document rather than a one-time compliance checkbox. The concrete next step for operators: review current AI disclosure practices against the updated recommendations, identify gaps in creative production and content labelling workflows, and confirm that vendor contracts reference the current version of the guidance.

No timeline for the next update was announced.
