Google Functionally Becomes a Marketplace

Following its recent I/O announcements, Google is shifting Search from a referral engine toward an integrated, agent-driven commerce experience. The company rebuilt the search box to prioritise AI answers, conversational follow-ups and autonomous agents, and introduced Universal Cart and an Agent Payments Protocol that enable checkout and autonomous purchases inside Google. The article argues these changes reduce clicks and referrals to external publishers, collapse layered publisher monetisation stacks, and transfer transaction and attribution data into Google’s infrastructure. It highlights publisher and advertiser risks (falling click-through rates and rising zero‑click searches) while identifying a commercial opportunity for affiliate and verification-focused content via a persistent “trust gap” — consumers still often verify purchases outside pure AI answers. The piece frames the announcements as a market shift with major implications for discovery, measurement and publisher revenue models.
