Google has started moving shopping ads to a model it calls agentic commerce. The idea: an ad stops being a door into someone else's store and becomes a point of sale in its own right — an AI agent answers the shopper's questions and payment happens inside Google's own surfaces. The timing is deliberate: the rollout lands right before holiday sales, when every abandoned cart is at its most expensive.
Abandoned carts are the target. The classic path — click, land on a site, register, type in a card — leaks people at every step. Google wants to replace it with a short conversation and a two-tap checkout without leaving Search or the video.
Four new tools
Share of Voice in AI Performance Insights. Merchant Center sellers in North America and a few priority markets get a dedicated report showing how often a store's products are recommended in AI Mode and AI Overviews. Effectively, the first official brand-visibility metric inside AI search.
Business Agent in YouTube. Video ads get a built-in consultant. A viewer asks about specs, size availability or delivery time mid-watch — the agent answers without interrupting the video or sending them to a site.
Checkout via UCP. The Universal Commerce Protocol syncs the cart across Google surfaces and lets users pay inside the search box or an assistant chat. The merchant gets the order; the payment itself happens on Google's side.
New feed ranking logic. Product cards for AI results are picked differently: priority goes to items with conversational attributes (which use cases, what to compare with), video demos and answered common shopper questions. A bare title plus price no longer competes.
What it means for e-commerce and product affiliates
First — feeds will need rewriting. Gemini matches products to natural queries like "gift for a dad who loves fishing", not to exact title matches. Cards without use cases, video and FAQ simply won't make the shortlist, whatever the bid.
Second — impulse purchases grow. With two taps between interest and payment, the "I'll think about it" crowd starts converting. Whoever rebuilds feeds for the conversational format and connects UCP first takes the cheapest conversions of the season — after that the auction inevitably heats up.
Third, the part Google does not say out loud: with in-SERP checkout the buyer may never reach the merchant's site. That hurts retargeting, first-party data collection and any analytics tied to landing-page visits. Anyone who earns on upsells and repeat orders should plan now for how to keep the customer when the first touch happens entirely inside Google.
What to do now
Check whether the Share of Voice report has appeared in your Merchant Center — it signals you are in the first wave. Go through top SKUs and add scenario attributes, short videos and a Q&A block. And watch the UCP documentation: integration will require work on the store side, better done before the seasonal peak than during it.
