The article is the full, canonical source. **Direct answer:** According to groas, Google Marketing Live 2026 on May 20 made Gemini the central operating layer across Search, YouTube, Shopping, and measurement, shifting advertiser control toward inputs, goals, and guardrails rather than manual keyword and bid management.

According to groas, Google Marketing Live 2026, streamed globally on May 20, positioned Gemini as the operating system layer connecting Search, YouTube, Shopping, and measurement.

The article reports three new ad formats built for AI Mode: Conversational Discovery ads that generate tailored creative for each AI Mode query, Highlighted Answers that embed sponsored responses in list-style AI responses, and AI-powered Shopping ads that auto-generate product explainers within conversational shopping queries. All three remain clearly labelled “Sponsored,” and the article notes AI Mode queries now run roughly three times longer than traditional searches, so copy designed for short-tail keyword matching will likely underperform.

According to groas, Ask Advisor is a unified Gemini-powered agent that spans Google Ads, Google Analytics, Merchant Center, and Google Marketing Platform inside a single interface. Advertisers can query it in natural language to pull insights, receive recommendations, and act on them, rather than switching between four dashboards. The article states access is rolling out progressively and advertisers should check whether their accounts qualify and begin testing early.

The article reports Universal Cart, announced at Google I/O on May 19, is a cross-merchant, cross-surface shopping cart that works across Search, Gemini, YouTube, and Gmail with checkout with Google Pay in a single transaction. Gemini tracks price changes, flags compatibility issues, and surfaces loyalty savings in the background. According to groas, Merchant Center feed quality now directly controls placement in agentic shopping flows, so retailers running Shopping campaigns should audit product titles, descriptions, images, pricing accuracy, and availability data immediately.

The article states Google Ads will limit hourly, daily, and weekly reporting data to a 37-month rolling window starting June 2026, while monthly and annual aggregates keep their existing 11-year window. Any granular data older than 37 months that has not been exported to BigQuery or another warehouse will be permanently gone. According to groas, agencies running year-over-year daily performance analyses or automated reporting pipelines are most exposed and should audit every account now.

According to groas, AI Max for Search has exited beta with Google reporting an average 7% uplift in conversions or conversion value at similar CPA or ROAS. Beginning September 2026, Dynamic Search Ads, automatically created assets, and campaign-level broad match campaigns will be forcibly migrated to AI Max. The article states migration tools are live now, giving advertisers roughly four months to test proactively while they still have a DSA baseline to compare against.
