Google Ads AI Video & Policy Updates 2026: Key Changes Advertisers Must Know

Google Ads is undergoing a wave of changes in August 2026 that will affect how advertisers create and manage campaigns — especially those using AI-generated content and video assets.

From mandatory AI disclosure labels to automatic video ad format upgrades, the updates span compliance, creative strategy, and campaign performance. This article breaks down every change, explains why it matters, and offers actionable steps for preparation.

Google Ads Introduces Mandatory AI Label Fields in Ad APIs

The single most impactful change for advertisers using AI-generated content is the new irreversible AI label field across two of Google’s ad APIs.

Driven by transparency obligations under the EU’s AI Act — which became applicable on August 2, 2026 — Google now requires advertisers to programmatically disclose when their ads contain AI-generated content. According to PPC Land, the label field is irreversible once set, meaning advertisers cannot retroactively remove or modify it after an ad is created.

Non-compliance carries significant penalties under the EU’s new regulatory framework, making this a high-priority change for any advertiser serving ads in the European Union or to EU-based users.

Why this matters: The AI Act is the world’s first comprehensive legal framework for artificial intelligence. Google is one of the first major ad platforms to implement mandatory AI content labeling at the API level. Advertisers who rely on AI for ad copy, image generation, or video creation must now build labeling into their production workflows from the start — not as an afterthought.

What AI content must be labeled?

While Google has not published an exhaustive list, the labeling requirement applies broadly to AI-generated or AI-modified content within the ad. This includes:

• AI-generated ad copy or headlines
• AI-generated or AI-modified images and video
• AI-driven dynamic creative optimization outputs

Advertisers should consult the latest API documentation and legal guidance to determine exactly which content types are subject to labeling. For most campaigns using Google’s AI-powered tools like Performance Max or Video campaigns, some degree of labeling will likely be required.

Google Publishes Long-Awaited Guidance for Text Disclaimers in Search Ads

In a move that provides much-needed clarity, Google has released new Help Center documentation covering how advertisers can use text disclaimers in Search ads globally.

As reported by Search Engine Land, the guidance covers compatibility with AI Max campaigns and explains best practices for meeting legal disclosure requirements directly within ad copy. This is especially important for advertisers in regulated industries such as finance, healthcare, and legal services.

Key takeaway: Advertisers now have an official, Google-endorsed framework for adding disclaimers without violating ad policies. The guidance covers where to place disclaimers, character limits, and how they interact with responsive search ad formats.

In-Stream Only Video Reach Efficient Reach Campaigns Are Being Upgraded to Multi-Format Ads

Beginning in August 2026, Google will automatically upgrade all in-stream only Video Reach Efficient Reach Campaigns to multi-format ads. According to Google Ads Help, this means advertisers can no longer run in-stream only video campaigns — they must provide headlines and descriptions to allow Google’s AI to optimize across multiple ad formats.

What this means for advertisers:

• In-stream video ads that previously ran alone will now also serve as skippable and non-skippable formats across YouTube and Google Video Partners.
• Advertisers must supply additional creative assets (headlines, descriptions, and optionally images) to fully leverage the multi-format capability.
• Google’s AI will automatically select and serve the best-performing format for each impression, potentially increasing reach and efficiency.

How to prepare for the multi-format upgrade

If you have existing in-stream only Video Reach campaigns:

1. Review your campaign settings starting now — the upgrade is automatic but you can optimize your assets before it takes effect.
2. Prepare at least 3-5 headlines and 1-2 descriptions that align with your video creative.
3. Consider creating square and vertical video variants if you haven’t already — multi-format campaigns can serve across YouTube Shorts and other surfaces.
4. Monitor performance closely in the weeks after the upgrade to identify any changes in reach or cost efficiency.

Target-Based Bid Strategies Get More Predictable Starting August 17, 2026

Google is updating its bidding systems to provide more consistent and predictable performance for target-based bid strategies, even when budgets are adjusted.

The change, detailed in Google Ads Help, applies to:

• Search campaigns
• Shopping campaigns
• Performance Max campaigns
• Demand Gen campaigns

A new Bid Target Adjustment Tool has been available since July 6, 2026 to help advertisers fine-tune their bids. Google also published a Q&A video addressing common questions about the update, including its impact on seasonal campaigns and budget changes.

Why this matters: Historically, adjusting budgets in target-based bid strategies could destabilize performance for days or weeks. The new system aims to minimize that volatility, making it easier to scale campaigns up or down without sacrificing efficiency.

Experimental: Anchor Text Hyperlinks in Ad Descriptions

In a smaller but noteworthy experiment, Google Ads is testing the inclusion of anchor text hyperlinks within ad descriptions. According to Search Engine Roundtable, this feature would allow advertisers to embed clickable links directly in the description text of their search ads.

Currently, all ad links are placed in the display URL and the final URL. If this feature rolls out broadly, it could open new possibilities for direct response campaigns — for example, linking to a specific product page, a booking form, or a lead generation landing page from the ad description itself.

What we know so far:

• The test is limited in scope and not available to all advertisers yet.
• It’s unclear whether hyperlinks will be allowed in responsive search ads or only in expanded text ads.
• Google has not announced a general rollout timeline.

How Advertisers Can Prepare for These Changes

The volume of simultaneous changes can feel overwhelming, but a structured approach will help:

1. Audit your AI-generated content

Review all ad creatives — copy, images, and video — for AI-generated or AI-modified elements. If you serve ads in the EU, you must implement AI labeling before your next campaign launch. Work with your legal team to ensure compliance with the EU AI Act.

2. Update your video campaigns

Check your Google Ads account for any “in-stream only” Video Reach campaigns. These will be upgraded automatically, but you should prepare creative assets now — especially headlines and descriptions — to ensure optimal performance after the upgrade.

3. Test the Bid Target Adjustment Tool

If you use target-based bidding (Target CPA, Target ROAS, etc.), experiment with the new Bid Target Adjustment Tool on a lower-spend campaign before the August 17 update. This will help you understand how the new system responds to budget changes.

4. Stay informed on hyperlink testing

While the anchor text hyperlinks experiment may not affect you directly yet, early adoption of new ad formats can provide a competitive edge. Keep an eye on official Google Ads channels for rollout announcements.

5. Review new security policies

Google Ads has also announced that free email accounts (like Gmail) will no longer be allowed to take sensitive actions on accounts. While not directly tied to the AI or video changes, it’s worth reviewing this update from Search Engine Roundtable to ensure your account access is properly configured.

The Bigger Picture: AI Regulation and Platform Evolution

The changes in August 2026 reflect a broader shift in the digital advertising landscape:

AI transparency is becoming mandatory. The EU AI Act is setting a precedent that other jurisdictions may follow. Advertisers should treat AI disclosure as a permanent operational requirement rather than a one-time compliance hurdle.

Google is pushing advertisers toward AI-optimized, multi-format campaigns. The forced migration of video campaigns to multi-format ads signals that Google wants advertisers to feed the AI more creative inputs — and then trust the algorithm to optimize delivery.

Bidding is becoming smarter but also less manual. Predictable bid strategies reduce the need for constant human oversight, but they also require advertisers to rely on automated systems. Understanding how your bids respond to budget changes is more important than ever.

Frequently Asked Questions

Q: When do the mandatory AI label fields take effect? A: The EU AI Act became applicable on August 2, 2026. Google has introduced irreversible AI label fields across two ad APIs to comply with this regulation. Advertisers serving ads in the EU should implement labels immediately.

Q: Will my existing in-stream video campaigns stop working? A: No, they will be automatically upgraded to multi-format campaigns starting in August 2026. However, you need to provide headlines and descriptions for the AI to optimize across formats; otherwise, performance may decline.

Q: How does the bidding update affect Performance Max campaigns? A: The August 17 update promises more consistent and predictable performance for target-based bid strategies across Search, Shopping, Performance Max, and Demand Gen, even when budgets are adjusted.

Q: Are anchor text hyperlinks available in all Google Ads accounts? A: No, this feature is currently in testing and only available to a limited set of advertisers. There is no general availability date yet.

Q: Do I need to add text disclaimers to every Search ad? A: Only if your ads require legal disclaimers under applicable regulations. Google’s new guidance provides best practices for adding them, but they are not mandatory for all advertisers.

Q: Can I opt out of the multi-format video upgrade? A: No, the upgrade is automatic and mandatory for existing in-stream only Video Reach campaigns. You can, however, control which headlines and descriptions you provide.

Q: What are the penalties for not labeling AI-generated ads? A: Under the EU AI Act, non-compliance can result in significant fines. Google’s reversal of the label field is irreversible, so failing to label properly could prevent ad approval or lead to account-level penalties.

Q: Will the bidding update affect my campaign costs? A: The update is designed to make performance more consistent, not inherently increase or decrease costs. However, if you adjust budgets, the system should react more predictably, which may change how your spend is distributed.
