Victorious says Google Universal Cart raises the bar for retailer data and checkout

Google’s new Universal Cart is live in the U.S., and Victorious says retailers have a narrow window before Black Friday to make sure their product feeds and checkout flows hold up. A test by Victorious CEO Michael Transon found two retailers sending shoppers to empty carts, underscoring the risk of lost sales and lost attribution.

Why it matters: - Google’s Universal Cart can influence which retailers win a shopper’s purchase when products from multiple stores are compared in one place. - Victorious says retailers with incomplete product data or broken checkout handoffs risk losing the sale before Black Friday on Nov. 27. - The cart can also shape whether Google or the retailer keeps the customer relationship after the click.

What happened: - Google launched Universal Cart in the U.S. on Oct. 15. - The cart lets shoppers save products from multiple retailers across Google Search and the Gemini app. - Shoppers can check out through Google Pay or on the retailer’s own website. - Victorious, an SEO and AEO agency focused on AI search visibility, said the feature makes product comparison easier while leaving the buying decision with the shopper. - Victorious CEO Michael Transon tested the cart and found two retailers allowed products to be saved, but the return links opened product pages with empty carts and no tracking parameters.

The details: - Universal Cart runs on Google’s Shopping Graph. - The Shopping Graph draws heavily on retailer Merchant Center feeds. - Those feeds include price, stock level, shipping and return policy data. - Retailers can configure checkout on Google, cart transfer to their own site, or both. - Google has not published Universal Cart fees. - Modern Retail reported in June that Google has no plans to take a cut of purchases. - The cart shows Google each product and price a shopper compares across stores.

Between the lines: - Transon framed the launch as a test of data quality and checkout reliability, not just a new shopping feature. - He said the brands that perform best will be the ones whose product data answers the shopper’s question and whose checkout works when the shopper is ready to buy. - Transon also cast the feature as a response to early agentic checkout results, including a March example from Walmart’s Daniel Danker that purchases completed inside ChatGPT converted at about one-third the rate of shoppers who clicked through to Walmart.com. - OpenAI said in March it would shift its checkout feature toward product discovery and merchant-run checkout. - Transon said the money for Google is likely in ads and in keeping the shopping journey inside Google, not in transaction fees.

What’s next: - Retailers have about five weeks to pressure-test their feeds and checkout paths before Black Friday. - Transon said shoppers and merchants should test both Google checkout and cart transfer flows the way a customer would. - Victorious is discussing the launch and where the cart may go next in episode 18 of The Search Signal podcast, also available on YouTube.

The bottom line: - Universal Cart rewards retailers whose product data is accurate, complete and ready for a shopper who wants to buy now, not browse later.
