Google Adds AI Tools To Search, YouTube And Checkout For Holidays

Cart handoffs to merchant sites and richer checkout tracking go live now in the U.S., with Australia and Canada added in early 2027.
- Google published "Boost your holiday sales with these agentic commerce updates" September 16, 2026, launching AI Performance Insights in five countries.
- "On average, merchants adopting core Merchant Center feed best practices see a 5% increase in conversions the following month."
- During lululemon testing, Google's AI used the retailer's product data in half of AI Mode recommendations.
Why it matters: Every tool that promises merchants more sales also feeds Google more control over how commerce data flows.
