Google, Microsoft Detail AI Advertising Updates

Advertisers that connect offline and app data to Google’s Data Manager see an average 26% increase in incremental ROAS, while enhanced conversions deliver an average 11% increase in Search conversions compared with standard conversion imports.
Google’s Data Manager API is now universally available and follows the IAB Tech Lab’s Event and Conversions API standard, providing a unified way to connect, manage and activate audiences and measurement across major advertising platforms.
Product Value Optimization allows advertisers to apply product-level or product-group multipliers without restructuring campaigns. Google’s illustrative examples assign multipliers of 1.2 to holiday promotions, 1.5 to high-margin products and 1.8 to overstock; these figures are examples rather than reported performance gains.
Microsoft recommends embedding AI disclosures directly into image and video assets when disclosure is required, while noting that machine-readable provenance signals, metadata and imperceptible watermarks may not be visible to consumers. Labeling alone does not make deceptive deepfakes, unauthorized impersonations or likeness misuse acceptable.
The latest Google AI Mode ad test places the new format between content in the search experience, adding to several other ad formats the company has recently been testing as it experiments with how sponsored material and AI-generated answers appear together.
Google and Microsoft are overhauling their advertising tools to give marketers stronger control over data and campaign results. Google is connecting its Data Manager with Google Analytics and Display & Video 360, while testing new ad formats in AI Mode and rolling out Product Value Optimization for retailers. Microsoft is requiring advertisers to clearly label AI-generated or manipulated content and warning that deceptive deepfakes remain banned regardless of disclosures.
The updates aim to improve how companies measure advertising impact and assign value to products based on profit, promotions or inventory levels. Google reports that advertisers connecting offline and app data to Data Manager see a 26% average increase in return on ad spend, while enhanced conversions deliver an 11% average boost in Search conversions.
Google is unifying how advertisers manage customer data across its ecosystem. The Data Manager API is now available to all advertisers and follows industry standards set by IAB Tech Lab. This gives marketers one central way to connect, manage and activate audiences across major ad platforms without building separate integrations for each system.
New integrations with Google Analytics help advertisers see the full customer journey. Enhanced conversions track transactions better than standard imports, delivering an 11% average lift in Search conversions. When companies link offline purchases and app events to Data Manager, they gain 26% more incremental sales per dollar spent, according to Google's internal testing.
Google is testing Product Value Optimization, letting e-commerce companies prioritize which products get promoted most aggressively. Advertisers can assign multipliers to different products without rebuilding their entire campaigns. The company shows examples: 1.2x for holiday promotions, 1.5x for high-margin items and 1.8x for overstock clearance, though these are illustrations rather than guaranteed results.
The tool works within Performance Max and Shopping campaigns, Google's AI-driven ad formats. Retailers can adjust product priorities on the fly as seasons change or inventory shifts. This gives smaller businesses the optimization power that once required manual campaign restructuring and constant monitoring.
Microsoft Advertising is requiring all advertisers to preserve digital signals that track an image or video's origin and history. When ads contain AI-generated or manipulated content, companies must add clear disclosures visible to consumers. The platform recommends embedding labels directly into images and videos rather than relying on text-only warnings.
The company made clear that labeling alone cannot save deceptive content. Deepfakes, fake celebrity endorsements and misleading manipulated media may still be rejected, even with AI disclosure badges. Microsoft is balancing innovation with consumer trust, preventing ads that could deceive viewers regardless of whether they carry warning labels.
Google is experimenting with how sponsored ads appear next to AI-generated answers in search results. The latest test places ads between AI content, adding to several other ad formats the company has recently piloted. This marks a new frontier: blending traditional advertising with generative AI in the search experience.
The tests signal Google's push to monetize its AI capabilities while keeping search valuable to users. By placing ads naturally alongside AI-generated results, the company can maintain advertiser reach without disrupting the AI experience. How these formats eventually roll out will shape digital advertising for years to come.
