Google will give advertisers more control and transparency over “text guidelines” for some AI-powered campaigns.

The company plans to roll out the feature in beta to all AI Max for Search and Performance Max customers, globally. It was previously offered to a limited number of advertisers.

The move will enable more advertisers to define terms or concepts to accept or avoid in specific campaigns, to ensure that AI-generated assets correctly represent the brand in tone, language preferences, and compliance requirements when generating the ad text.

As "text customization" matches the creative with intent, while "text guidelines" ensures that the message remains on-brand.

Advertisers provide header and description assets such as "The new Smart Phone," "Our most innovative Smart Phone yet" or "Safe and secure."

Then Google automatically creates headline and description assets such as "Impressive from every angle," "Trade-in offers available," or "Several colors to choose from."

While it’s reasonable for platforms to expand tools that give advertisers more control over their messages, this update underscores a larger trend that should concern marketers and policymakers alike: the increasing reliance on automated systems to generate substantive campaign content. Google’s text guidelines may help protect brand voice and compliance, but they also remind us that much of the creative work is now delegated to AI, with humans merely setting guardrails rather than driving the narrative. Rather than lean into automation by default, brands — including political campaigns — should insist on human oversight, strategic intentionality, and accountability in every message that goes live. Automation should augment human decision-making, not replace it. And as these tools proliferate, transparency around how AI shapes messaging and impacts audiences must be paramount so that advertisers aren’t blind to how their voice is being mediated. ~Political Media Inc.
