Google Rethink ROI: Lululemon AI Mode hits 50%

Google's Rethink ROI summit in New York served as a stage for the company's push to embed AI deeper into shopping discovery. The new conversational attributes are designed to let retailers feed structured data—such as FAQ, compatible accessories, and substitutes—straight into the Shopping Graph, the system that powers product recommendations. Early testing with Lululemon showed that brand-supplied attributes made their way into AI Mode recommendations half the time, a signal that the quality and completeness of a retailer's product data can directly affect its visibility in AI-driven search.

That visibility matters because shoppers are increasingly arriving at retail sites through AI tools. Adobe Analytics recorded an 805% year-over-year jump in AI-driven traffic to retail sites during Black Friday 2025, and those visitors converted 38% more often than non-AI shoppers. Salesforce Cyber Week data adds that retailers with integrated AI agents grew sales 32% faster than those without. Yet the infrastructure to actually complete those purchases autonomously is lagging: the TLT LLP Retail Agility survey of the top 100 UK retailers found that while 49% are investing in agentic AI, only 15% say their payment systems are ready for transactions initiated by AI agents.

Google is trying to bridge that gap with the Universal Commerce Protocol and the Universal Cart framework, which aim to enable persistent, cross-platform shopping carts across Search, YouTube, and Gmail. The stakes are clearest with Black Friday 2026 now 10 weeks away. The 32% growth uplift seen by AI-integrated merchants suggests consumer demand is real, but with only 15% payment readiness, most retailers risk losing that demand if they do not harden their back-end systems. The next two months will likely determine which brands can move from discovery-focused AI to transaction-ready agentic commerce.
