Google Rolls Out Veo Video Generation, Text Disclaimers, and DSA Migration Timeline
Google published a detailed Ads Decoded episode on May 6 covering five operational changes for advertisers working with AI creative tools. The episode features Google Ads product leaders walking through Veo video generation integrated into Asset Studio, text disclaimers for regulated industries, video voiceovers in Performance Max, and the September 2026 deadline for Dynamic Search Ads retirement.
The timing matters. April 30 brought simultaneous announcements of AI Brief, AI Max for Shopping, and text disclaimers. The video episode provides technical specifics and performance data that blog posts omit.
Ad Strength Measures Asset Diversity, Not Performance
A recurring source of confusion among creatives: ad strength doesn't predict conversions. The metric uses a mathematical algorithm called cosine similarity to measure how unique individual headlines and descriptions are relative to each other within a responsive search ad.
Ad strength signals inventory eligibility. 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. Incomplete aspect ratio coverage leaves impressions unreached regardless of creative quality.
An asset with few impressions but positive conversions usually indicates it's reaching a niche audience and performs well in combination with others. An asset showing very few impressions and zero conversions after several weeks signals poor auction competitiveness and should be replaced. The guidance is to create new assets that produce "unique combinations"-different pairings of headlines and descriptions serving across broader search intents.
Veo Video Generation Now Built Into Google Ads
Generative video capability is now accessible directly through Video Builder and Asset Studio in Google Ads. The workflow targets image-only advertisers without video production capability: select up to three images, and the system generates five 10-second videos from those inputs.
This addresses a structural gap. Demand Gen campaigns require video to access all YouTube inventory-connected TV, in-stream ads, and Shorts. Advertisers running only image assets cannot reach the full inventory surface. Veo integration closes that gap without requiring API access or external video production.
Google is also testing a product-to-video mapping pilot for retailers. The scenario: a retailer with hundreds of thousands of SKUs in a Google Merchant Center feed could eventually have individual videos mapped to specific products. Demand Gen would serve the video corresponding to the product a user is most likely to purchase. The pilot is small-scale with no timeline for broader availability.
Video Enhancements Include AI-Generated Voiceover
Video enhancements-automated modifications Google applies to existing video assets-are active in Performance Max. A recent internal experiment showed Demand Gen ads with video enhancements saw over 16% increase in conversion value at targeted ROI on YouTube.
The newest addition is voiceover, currently rolling out in Performance Max. The system generates spoken audio layered onto existing video ads. The voiceover script draws from the advertiser's existing headlines and descriptions, keeping output within the brand's stated messaging.
Google plans to add preview functionality so creatives can hear what a voiceover will sound like before it serves. This falls under what Google calls "advertiser in the loop" solutions-features that increase transparency about automated changes before they take effect.
Text Guidelines Cap at 40 Restrictions Per Campaign
Text guidelines are available across Search campaigns with AI Max enabled and Performance Max. The feature allows creatives to specify content the system should avoid when generating AI-assisted copy.
There are two layers: a default set that applies automatically when text customization is active (preventing price or availability claims the system cannot verify), and a custom layer where creatives can add restrictions. The cap is specific-up to 40 guidelines per campaign. The system checks every generated asset against each guideline before it serves.
A practical example: a coat retailer that doesn't want products described as cheap or with certain material descriptors can write both as guidelines and the system enforces them at asset generation.
Text guidelines reached global availability on February 26, 2026. Advertisers with AI Max enabled who add text customization and Final URL expansion see, on average, 7% more conversions at similar cost per acquisition compared to search term matching alone.
Text Disclaimers Resolve a Long-Standing Compliance Problem
Healthcare, financial services, and regulated advertisers have needed this for years. They couldn't combine pinned disclaimer copy with Final URL expansion because the two features conflicted at the description level. Text disclaimers now rolling out for Search campaigns resolve this directly.
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 a description is pinned to the first position, the disclaimer overrides it. The two cannot function simultaneously.
On the Demand Gen side, disclaimers are in a more limited state. Google is running an active pilot across key YouTube formats, beginning with healthcare advertisers who have the clearest legal requirements. Learnings from that pilot are expected to feed into a more widely available offering for sensitive verticals later in 2026.
Dynamic Search Ads Retirement: September 2026 Deadline
Advertisers still running DSA campaigns have a choice: migrate voluntarily now or face automatic migration beginning in September 2026. All eligible campaigns are 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.
Google frames AI Max as "the evolution of DSA with 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. Where DSA pulled assets directly from the landing page, AI Max adapts those assets to match user intent at query time.
Reporting also improves. Advertisers gain deeper asset reports and the ability to apply text guidelines-neither of which existed in DSA format.
Performance Max Asset Comparison Experiments Available Now
Performance Max now supports asset comparison experiments-direct A/B testing with two sets of creatives measured against each other. The structure is designed so creative is the only variable changing between test arms.
This feature is expected to extend to Demand Gen later in 2026. The broader principle applies to testing both individual assets and the effect of automation itself-running with and without AI Max or asset optimization to measure what the automation contributes.
Final URL Expansion Reporting Now Complete
Previously, Final URL expansion reporting provided limited visibility: impression stats only in Search, conversion stats only in Performance Max. Full stats are now available for every title and URL combination in both Search and Performance Max. Creatives can now see complete performance for each automatically generated landing page and headline pairing-clicks, impressions, conversions, and conversion value.
Google Marketing Live is scheduled for May 20, 2026. The next Ads Decoded episode is expected to air following the keynote.
