Your Google Ads account will start serving a buyer you can’t see. That shopper is an AI agent that compares products and exits on your customer’s behalf.
Agent trading is going to be the biggest change in paid ecommerce media since mobile, and of course it’s moving real money. At Cyber Week 2025, Salesforce said that an estimated $67 billion in global sales, about 20% of all orders, will be from AI and agents. That was not an estimate or a forecast for the coming year; that was the last holiday season.
Your product feed now turns into a bidding signal instead of a catalog, and a new paid area opens up within Google’s AI Mode. Performance Max and Purchases begin to place in that specific area, and tracking your conversions breaks down in ways that depend on how the agent evaluates. This is going to be a tough journey.
None of this means your current campaigns stop working. It means the inputs that determine whether you win change, and accounts that fix early get the real edge.
What’s Latest in Agentic Marketing
A quick primer, because this space moves quickly and the headlines blur together.
Google Pay, dubbed Buy for Me, is live in AI Mode with startup partners including Wayfair, Chewy, and Quince. At NRF 2026, Google introduced the Universal Commerce Protocol, an open standard developed by Shopify, Etsy, Walmart, and Target, and endorsed by more than 20 companies, including Visa and American Express. OpenAI has ported Instant Checkout to ChatGPT through its proprietary Stripe protocol. Confusion has been associated with PayPal. Visa, Mastercard, and Stripe are all agent-friendly payment instruments issued.
If acquisitions, exits, and payments all reschedule for agents within 12 months, this is not a wait-and-see startup.

Your Feed Is Now A Bidding Signal For Google Ads
In Shopping and Performance Max, your product feed is already compatible with bidding. Agents take that further. When an AI agent checks products, it doesn’t read your ad copy or your creative. It reads the order data, price, availability, shipping, returns, and specs in your feed, and decides if you make the shortlist before anyone sees anything.
OpenAI’s evaluation of its shopping research tool makes the point. The tool achieved a product accuracy of 52% for the most complex queries compared to 37% for standard ChatGPT searches, where product accuracy measures how well results match criteria such as price, color, material, and specs. Buyers give agents strict limits, and the agent matches those limits against your feed fields.
Google has noticed where the lever sits. Released new Merchant Center features that specifically help products appear in conversational shopping.
The takeaway for the premium team is not comfortable but simple. Feed quality is now a bidding issue, not a hygiene issue. If your feed is from whoever set up a Merchant Center two years ago, while your budget and attention goes to innovation, you can go back to this site. We treat the feed as a media asset now, the same way we offer a smart test system.
Direct Offer is the New Paid Placement for Google Ads
One area that most paid media outlets have not yet achieved is the engineering trade to come up with an actual ad product.
Direct Offers is a Google Ads driver that throws merchant-sponsored promotions directly into AI Mode when the system learns the consumer as a prime target. You set the offer in your campaign settings, and Google decides when to show it. Google Ads Link described the format as less like a standard ad and more like a seller negotiating a deal on behalf of a buyer.
Stay tuned for what that means for the media buyer.
You are no longer only bidding on the property. You decide how much margin to give up at the exact moment of the decision, within the interface controlled by Google.
That cuts two ways. The danger is obvious. If the depth of the discount is the only lever, this surface area becomes a margin race, and the negative brands win. The opportunity is that Google has already said it will expand Direct Offers beyond price to value, naming loyalty benefits and product bundles. Brands that develop a pricing strategy early on compete on something other than how much they will bleed.
Decide your position before you choose to enter. What products, what is the margin floor, and whether you lead on price or value.
PMax and Shopping Ads Now Enter AI Mode
Here is the development that makes this concrete for anyone using Performance Max. Starting in February 2026, Google began serving shopping ads within AI Mode, and those placements are served from your existing Shopping and Performance Max campaigns, marked as sponsored.
So your workhorse campaigns are already feeding the agent’s link, whether you planned it or not. Catching visibility. Some journeys now take place within AI Mode, where you see a little of what’s going on, and Performance Max was already the most obscure type of campaign offered by Google.
This is the same growing gap seen with AI Max, where query expansion widens the distance between what you’re bidding on and what actually converts. Agents are very simple.
The good news is that Google brought back native controls last year, so use them. Channel-level reporting shows where budget is going across Search, Shopping, YouTube, and more. Campaign-level negative keywords are no longer a support request. And the visibility of search terms in Performance Max finally reaches what Standard Shopping has always offered. If you’re not using these to keep branding and non-branding legible, you’re not as good as you need to be.
Agentic Checkout Breaks Two-Way Tracking
Your description was already incomplete. Agents break down in two distinct ways, and which one hits you depends on how the buyer evaluates.
The first method is Buy for Me, where the agent completes the purchase on your site and you remain the seller of record. Google docs are clear that the transaction is happening on your site, so your conversion tag can still fire. What’s broken is the link back to the campaign that won the sale, because the agent’s session doesn’t have an ad clickable to test how regular visits are doing. You keep the conversion, but you lose the attribute. Better than losing both, I guess?
The second route is to remove the power of UCP, where the purchase takes place directly on the Google site within AI Mode or Gemini. You’re still the seller of record, so you still get the order, but the sale never happens during the browser’s time on your site. That means your client-side tracking doesn’t see, your pixel, or any Meta or other field tags included, because there’s no on-site event they can catch. You rely on conversion data coming back through Merchant Center instead. The worst of the worst options.
I can’t tell you exactly how that UCP conversion appears in Google Ads, or whether other platforms see something, because Google hasn’t documented that cleanly yet. I’m also not going to tell you that you shouldn’t do this because you lose visibility and lose pixel tracking without a customer hitting your website.
What I’m going to tell you to do is stop it, watch that space closely, and don’t trust the forum OR the random person who claims to know. Check them out and confirm them.
What you can do now is concrete:
- Get server-side tracking and advanced conversions in place, to capture every catch.
- Set the original trade attribute and your UCP feed.
- Put more weight on combined efficiency and expansion, because field numbers will tell you less truth than ever before.
This is the time to move fast, adapt, slow things down, and embrace these changes early because you are more likely to be ahead of your competition. And, as things get smaller, you’ll be through it while others are on the front lines.
The Agentic Commerce PPC Playbook: What You Should Do Now
None of this is cause for panic or active layoffs. It’s a reason to get a few things in order while the top is still young.
- Treat your product feed as a bidding asset. Fill in every field of limitations, keep it accurate, and update it regularly. Installation is won or lost here.
- Make pricing, shipping, returns, and availability machine-readable and accurate. These are the agents that are read first.
- Determine your Direct Offers status before opting in. Choose products, set a margin floor, and choose whether you earn on price or value.
- Strengthen High performance and purchasing controls. Use reporting at the channel level and negative at the campaign level, and protect your brand traffic.
- Increase the rate now. Server-side tracking with improved capture conversions, escalations, and real-time aggregate performance metrics.
- Confirm your eligibility in key areas. Buy for Me requires Google Pay and a guest payment option, and Shopify merchants have a quick login.
- Don’t budget for Search and Meta just yet. This includes. The vast majority of your revenue still flows from the campaigns you’ve already run.
The Real Agetic Shift in Ecommerce
Advertisers who win in business won’t be the ones with the smartest ads. It will be their product data, margin position, and valuation that is perfect for a consumer who never sees an ad. This is not something you should be planning yet; you must continue this because Agentic Commerce has arrived.
The agent becomes the client you prepare for, and judges you on entries that most accounts take as an afterthought. This is a real change in ecommerce that deserves your attention.
