Google today published a new episode of its Ads Decoded video series focused on AI creative tools across Search, Performance Max, and Demand Gen campaigns. The episode, titled "On-brand, at scale: Driving performance with AI creative," was hosted by Ginny Marvin, Google Ads Product Liaison, with guests Charles Boyd, Group Product Manager for Creative at Google Ads, and Sarah Hathiramani, Director of Product Management for YouTube Ads. The conversation covers a wide range of practical topics - from how ad strength actually works under the hood to why text disclaimers matter for regulated industries, and what advertisers should do before the September 2026 Dynamic Search Ads deadline.

The episode arrives at a dense moment in the Google Ads product calendar. April 30, 2026 brought several simultaneous announcements, including AI Brief, AI Max for Shopping, and text disclaimers for regulated advertisers. The Ads Decoded episode provides a more detailed operational walkthrough than the blog posts, with specific figures and technical mechanics that practitioners will find relevant.

What ad strength actually measures - and what it does not

A recurring theme in the episode is the gap between what ad strength signals and how it gets interpreted. Boyd describes the metric as using a mathematical algorithm called cosine similarity to measure how unique the individual headlines and descriptions in a responsive search ad are relative to each other. The score reflects the number of unique asset combinations available - not whether those assets are currently generating conversions.

"Ad strength is important, but insufficient," according to Hathiramani, who frames the metric as covering inventory eligibility above all. For Demand Gen, this means images and videos must cover all required aspect ratios - landscape for desktop and connected TV, vertical for Shorts, square for in-feed placements. If aspect ratio coverage is incomplete, potential impressions are left unreached regardless of creative quality.

The episode clarifies a practical scenario that confuses many advertisers: an asset with a small number of impressions but positive conversions. According to Boyd, this usually indicates the asset is reaching a niche audience and is likely valuable when it serves in combination with others. By contrast, an asset showing very few impressions and zero conversions after several weeks signals poor auction competitiveness and is a candidate for replacement. The guidance is to replace underperforming assets with new ones that create what Boyd calls "unique combinations" - different pairings of headlines and descriptions that can serve across a broader range of search intents.

Hathiramani recommends looking beyond ad strength to the YouTube Ads Leaderboard, describing it as a filterable dashboard that can surface creative approaches from advertisers with similar marketing objectives. The leaderboard functions as an exploratory reference rather than a performance benchmark.

Veo enters the Google Ads workflow for image-only advertisers

One of the more technically specific segments concerns Veo, Google's generative video model. According to Hathiramani, Veo is now accessible to advertisers directly through Video Builder and Asset Studio in Google Ads. The workflow is designed for advertisers who have image assets but no video production capability: an advertiser selects up to three images, and the system generates five 10-second videos from those inputs.

This is explicitly positioned for "image only advertisers who've really been unable to unlock the full power of YouTube without having video assets," according to Hathiramani. The three images provided by the brand serve as the creative grounding for what the model generates - giving advertisers some control over the visual voice of the output without requiring them to manage a video production pipeline.

The broader context matters here. Demand Gen campaigns require video to access all available YouTube inventory: connected TV placements, in-stream ads, and Shorts. Advertisers running only image assets cannot access the full inventory surface. Veo's integration into Asset Studio is intended to close that gap. Earlier coverage on PPC Land tracked Veo 3 Fast becoming available through the Gemini API in July 2025, priced at $0.40 per second with audio. The Asset Studio integration brings a simplified version of that capability directly inside the Google Ads interface, without requiring API access.

The episode also notes an ongoing pilot around product-to-video mapping for retailers. Hathiramani describes a scenario where a retailer with hundreds of thousands of SKUs in a Google Merchant Center feed could eventually have individual videos mapped to specific products - allowing Demand Gen to serve the video that corresponds to the product a given user is most likely to purchase. "We recently started a small pilot to test having a more complete mapping of videos to individual products," according to Hathiramani. The pilot is small-scale; no timeline for broader availability is mentioned.

Video enhancements and the voiceover rollout

The episode provides updated detail on video enhancements, a category of automated modifications Google applies to existing video assets. According to Hathiramani, the program is active in Performance Max and covers modifications designed to reduce the cost of creative development while improving performance. According to a recent internal experiment cited in the episode, Demand Gen ads with video enhancements saw over a 16% increase in conversion value at the targeted ROI on YouTube.

The newest addition to video enhancements is voiceover. The feature, currently rolling out in Performance Max, generates spoken audio layered onto existing video ads. Marvin clarifies that the voiceover script is not independently generated - it draws from the advertiser's existing headlines and descriptions. The grounding in advertiser-provided text is intended to keep the output within the brand's stated messaging. PPC Land reported in March 2026 on the initial voiceover rollout notification, which gave Performance Max advertisers until March 20, 2026 to opt out before automatic activation.

Boyd notes that the team plans to add preview functionality so advertisers can hear what a voiceover will sound like before it serves. He describes this as part of what Google calls "advertiser in the loop" solutions - features that increase transparency about automated changes before they take effect. The phrase covers a broader category of controls being built across campaign types, including text guidelines and AI Brief.

Text guidelines and the 40-restriction cap

Text guidelines are available today across both Search campaigns with AI Max enabled and Performance Max, according to Boyd. The feature allows advertisers to specify content the system should avoid when generating AI-assisted ad copy. Boyd describes two layers: a default set of guidelines that applies automatically when text customization is active (preventing the system from including price or availability claims it cannot verify), and a custom layer where advertisers can add their own restrictions.

The cap is specific: advertisers can specify up to 40 guidelines per campaign. The system checks every generated asset against each guideline before it serves. Boyd gives a practical example - a coat retailer that does not want its products described as cheap, or that wants to avoid certain material descriptors. Both can be written as guidelines and the system enforces them at asset generation.

Text guidelines reached global availability on February 26, 2026, after a restricted beta that began in September 2025. The global expansion brought full language and vertical support, meaning advertisers outside English-speaking markets could apply the controls to campaigns in any language available in the Google Ads interface. The episode notes a performance data point: advertisers with AI Max enabled who then add text customization and Final URL expansion see, on average, 7% more conversions at a similar cost per acquisition compared to using search term matching alone.

That 7% figure is a revised benchmark. When AI Max for Search launched in May 2025, Google cited a 14% conversion uplift. The lower figure was introduced alongside the April 15, 2026 announcement that declared AI Max out of beta and confirmed Dynamic Search Ads would be retired in September 2026.

Text disclaimers: a long-requested feature for regulated industries

The most practically significant announcement for healthcare, financial services, and other regulated advertisers is text disclaimers, which are now rolling out for Search campaigns. The need has existed for years - advertisers subject to legal disclosure requirements have been unable to combine pinned disclaimer copy with Final URL expansion, because the two features conflict at the description level.

The implementation resolves this directly. According to Boyd, when a disclaimer is specified for a Search campaign, the designated text serves as the first description line in every ad - regardless of whether text customization or Final URL expansion is active. The disclaimer persists unconditionally. One important caveat: if an advertiser also has a description pinned to the first position, the disclaimer overrides it. When the disclaimer is disapproved or paused, the pinned description can then serve. The two cannot function simultaneously.

On the Demand Gen side, the feature is in a more limited state. Hathiramani describes an active pilot testing ad disclaimers across key YouTube formats. The pilot began with healthcare advertisers, who have the clearest legal requirements around disclosure language in ad copy. According to Hathiramani, the learnings from that pilot are expected to feed into a more widely available offering for advertisers across sensitive verticals later in 2026. No specific date is provided.

The DSA transition: what changes in September 2026

The episode addresses the DSA migration directly, framing it as a deadline with operational implications. Marvin states that advertisers have controls and tools to make the transition themselves and that Google "strongly recommend doing before the auto migration starts happening in September."

Boyd describes AI Max as "the evolution of DSA with some major upgrades." The structural differences are significant. DSA targeting was based on landing page content alone; AI Max combines landing page data with real-time intent signals and asset optimization together. Where DSA would pull assets directly from the landing page, AI Max adapts those assets to match the user's intent at query time. There is also a reporting improvement: advertisers gain deeper asset reports and the ability to apply text guidelines - neither of which existed in the DSA format.

As PPC Land covered on April 15, 2026, automatic upgrades begin in September 2026, with all eligible campaigns expected to complete migration by the end of that month. New DSA campaigns cannot be created via Google Ads, Google Ads Editor, or the Google Ads API from September onward. The voluntary migration path, opened alongside that announcement, allows advertisers to migrate before the automatic change - preserving the ability to review and adjust settings prior to the transition.

The episode is also one of several recent signals that AI Max is becoming the default targeting infrastructure for Google Search advertising. AI Max for Shopping launched on April 30, 2026, extending the framework to standard Shopping campaigns with text customization, Final URL Expansion, and Optimal Format Selection. The AI Brief feature, also announced on April 30, 2026, introduced a natural-language instruction layer inside AI Max that subsumes the existing text guidelines framework.

Asset testing in Performance Max and Demand Gen

Boyd and Hathiramani both address the state of creative testing in automated campaigns. Performance Max now supports asset comparison experiments, which allow a direct A/B structure: two sets of creatives tested against each other, with quantitative measurement of the performance difference. Hathiramani describes this as a "guided experience" designed so that the creative is the only variable changing between test arms.

The feature is expected to extend to Demand Gen later in 2026. Boyd frames the broader principle as testing not just between two assets but also testing the effect of adding automation - running with and without a feature like AI Max or asset optimization to measure what the automation itself contributes. That framing positions testing as a way to validate the automation layer, not just individual creative choices.

Merchant Center feeds and YouTube product targeting

A segment of the episode focuses on the intersection of Google Merchant Center product feeds and Demand Gen creative. Hathiramani points to the five-video limit that currently applies in Demand Gen campaigns - an advertiser with hundreds of thousands of SKUs in their feed cannot practically create one video per product. The product-to-video pilot described earlier is a direct response to this constraint.

The episode also highlights feed attributes like promotion assets and installment offers as underutilized creative elements. For advertisers with these data points properly populated in Merchant Center, the feed can communicate information - price, availability, current promotions - that ad copy cannot convey as efficiently. According to Hathiramani, keeping Merchant Center data accurate and high fidelity is a form of creative investment, because it reduces the burden on individual ad assets to convey that information directly.

Reporting improvements for Final URL expansion

Boyd closes with a specific reporting update. Previously, final URL expanding reporting provided limited visibility: impression stats only in Search, conversion stats only in Performance Max. The full suite of stats is now available for every title and URL combination in both Search and Performance Max. This means advertisers can now see the complete performance picture for each automatically generated landing page and headline pairing - clicks, impressions, conversions, and conversion value - rather than a partial view.

The episode closes with a mention of Google Marketing Live, scheduled for Wednesday, May 20, 2026. The next Ads Decoded episode is expected to air on the live stream following the keynote.

Timeline

Summary

Who - Google, represented by Ginny Marvin (Ads Product Liaison), Charles Boyd (Group Product Manager, Creative, Google Ads), and Sarah Hathiramani (Director of Product Management, YouTube Ads), in the Ads Decoded series published today.

What - A detailed walkthrough of current and incoming AI creative features across Google Ads, including: Veo video generation from images inside Asset Studio and Video Builder, video enhancements with voiceover in Performance Max, text guidelines and their 40-restriction cap, text disclaimers now rolling out for Search campaigns, Performance Max asset comparison experiments, and a product-to-video mapping pilot for Demand Gen retailers. The episode also clarifies how ad strength uses cosine similarity to measure asset diversity rather than performance.

When - The episode was published on May 6, 2026. Text disclaimers for Search campaigns are rolling out now. The DSA automatic migration begins in September 2026. Demand Gen text disclaimers and asset comparison experiments are expected later in 2026. Google Marketing Live is scheduled for May 20, 2026.

Where - Google Ads platform globally, across Search, Performance Max, Demand Gen, and YouTube inventory. Asset Studio is accessible under Tools in Google Ads. Veo's video generation capability is available through Asset Studio and Video Builder.

Why - The episode addresses a structural tension in AI-assisted advertising: automation increases reach and reduces production cost, but advertisers in regulated industries, brand-sensitive categories, and complex account structures need specific controls to make automation usable. Features like text disclaimers, text guidelines, voiceover previews, and deeper asset reporting are responses to that gap. The DSA transition is the most operationally urgent item for advertisers still running legacy Dynamic Search Ads campaigns - voluntary migration is open now, and the automatic change begins in September 2026.
