Google Demand Gen Campaign Compliance Guide 2026: Creative Requirements, Audience Signals & Policy Differences from Discovery Ads

What Changed: Discovery Ads to Demand Gen

Google's transition from Discovery Ads to Demand Gen campaigns represents the most significant restructuring of its visual advertising ecosystem since Discovery Ads launched in 2019. The mandatory migration, which began in October 2023 and completed across all accounts by March 2025, was not merely a rebrand — it fundamentally expanded the campaign type's capabilities, placement surfaces, and automation features. For compliance professionals, these expansions introduce new risk vectors that did not exist under the original Discovery Ads framework.

The core changes are structural. Discovery Ads served across three surfaces: YouTube Home feed, Google Discover, and Gmail Promotions and Social tabs. Demand Gen retains all three and adds YouTube Shorts, YouTube in-stream, and YouTube Search results as eligible placement surfaces. This tripling of video-capable placements means advertisers must now ensure creative compliance across substantially more format and context variations.

Migration Timeline and Compliance Implications

"Advertisers who treated the Discovery-to-Demand-Gen migration as a simple rename are now discovering compliance gaps they didn't anticipate. The campaign type has fundamentally different capabilities — and fundamentally different compliance obligations."

The most consequential change for compliance is the introduction of Automatically Created Assets (ACA), which uses Google's generative AI to produce headline and description variations from your seed creative and landing page content.

Demand Gen Creative Requirements

Demand Gen campaigns accept three creative formats — single image, video, and carousel — each with specific technical and policy requirements.

Image Creative Specifications

Video Creative Specifications

• Aspect ratios: Landscape (16:9), square (1:1), and vertical (9:16). Providing all three ensures optimal delivery and prevents forced cropping that can obscure required disclosures.
• Minimum duration: 10 seconds. Recommended 15 seconds or longer for feed placements and 6–15 seconds for Shorts.
• Audio requirements: Sound-on is expected. All spoken claims must be substantiated and consistent with text overlay claims.
• Disclosure placement: Required legal disclosures must be visible for a minimum of 5 seconds and must not appear only in the final frame.

Carousel Creative Rules

• All cards must link to the same domain — cross-domain linking triggers disapproval.
• Each card's headline (40 chars max) and description (90 chars max) must independently comply with Google's ad text policies.
• Promotional pricing shown on carousel cards must match the landing page price at the time of serving.

AI-Generated Creative & Automatically Created Assets

Google's Automatically Created Assets (ACA) feature, enabled by default in Demand Gen campaigns since Q3 2024, uses generative AI to produce additional headline and description variations. In 2026, Google expanded ACA capabilities to include image background generation and product image enhancement for e-commerce advertisers.

How ACA Creates Compliance Exposure

The fundamental compliance problem with ACA is that the advertiser is responsible for content they did not write. Google's terms are explicit — advertisers bear full responsibility for all ad content, including content generated by Google's AI tools.

• Claim substantiation: ACA may elevate a minor landing page mention into a prominent ad claim that constitutes an impermissible health or financial claim.
• Regulatory disclosure: ACA-generated descriptions may omit required disclosures that your manually created ads include.
• Trademark compliance: ACA may incorporate competitor brand terms from your landing page content into ad headlines.
• Accuracy drift: As Google's AI model updates, ACA outputs can change over time without advertiser action.

"Automatically Created Assets are not auto-compliant assets. Every AI-generated variation must be reviewed with the same rigor as manually created ad copy — arguably more rigor, because the advertiser did not choose the specific language used."

Controlling ACA Compliance Risk

Advertisers can disable ACA entirely at the campaign level — this is the recommended approach for regulated industries. For non-regulated advertisers, review the Asset Report at minimum weekly and remove any variations that present compliance concerns. Google also allows advertisers to pin specific headlines and descriptions to prevent ACA from replacing them.

Audience Signal Compliance

Demand Gen campaigns use audience signals rather than traditional audience targeting. In Search or Display campaigns, your audience targeting defines a hard boundary. In Demand Gen, audience signals are suggestions that inform Google's optimization, but the algorithm can serve ads beyond those signals.

Optimized Targeting: The Default Expansion

Optimized targeting is enabled by default. It allows Google to expand delivery beyond your defined audience signals by 2–5x. For compliance-sensitive campaigns:

• Age expansion: Your audience signal may specify adults 25–54, but optimized targeting can expand to younger demographics. Critical risk for age-restricted products.
• Geographic expansion: Optimized targeting may expand to adjacent markets where your product may not be legally available.
• Interest expansion: May serve ads to users in adjacent but not identical categories, creating contextual relevance issues.

For regulated industries, disabling optimized targeting is strongly recommended.

Customer Match Compliance Requirements

Placement Compliance Across Surfaces

Demand Gen campaigns can serve across six distinct placement surfaces, each with its own compliance profile.

Placement-Specific Compliance Guide

Google Discover: The Strictest Placement

Discover applies a dual policy layer. Ads must comply with both Google Ads policies and Discover content policies, which prohibit sensationalized language, misleading implications, and clickbait-style headlines. AI-generated images must not depict realistic scenarios that could be mistaken for photojournalism.

Policy Differences: Demand Gen vs Search/Display

"The compliance mindset for Demand Gen must be fundamentally different from Search. In Search, you control what goes live. In Demand Gen, you influence what goes live — and the algorithm fills in the gaps. Your compliance framework must account for those gaps."

Compliance Checklist for Demand Gen Campaigns

Pre-Launch Compliance Checklist

Ongoing Monitoring Checklist

• Weekly: Review Asset Report for new AI-generated variations; check placement delivery breakdown; monitor audience demographics for expansion beyond intended targets
• Bi-weekly: Audit ad disapprovals and policy warnings in Policy Manager; review Customer Match list health
• Monthly: Full creative compliance review against current Google Ads policies; verify all active AI-generated assets remain accurate
• Quarterly: Comprehensive compliance audit including Customer Match consent documentation and cross-market regulatory alignment

For automated compliance monitoring, our AI Compliance Audit tool can scan your Demand Gen campaigns against current Google Ads policies and flag potential violations before they trigger disapprovals.

Incident Response Protocol

1. Identify the source: Determine whether the violation came from a manually created asset, an AI-generated variation, a placement-specific issue, or an audience expansion issue.
2. Contain immediately: Pause the affected ad group to prevent similar AI-generated variations from continuing to serve.
3. Remove the root cause: If ACA generated the violating content, disable ACA and remove the seed assets. If audience expansion caused it, disable optimized targeting.
4. Appeal if appropriate: File an appeal through Google Ads Help only after implementing corrective measures.
5. Document and prevent: Record the violation type, root cause, and corrective action. Update your pre-launch checklist.
