This conversation has some real gold nuggets. It gets into what is actually changing with Google Shopping right now.

Google Shopping is undergoing a fundamental shift and is increasingly becoming AI driven commerce, but now commerce agents are increasingly playing a greater role in deciding what gets seen and sold than ever before. To optimize return on investment, small businesses must pivot their approach by understanding and using the key levers. You cannot just turn on PMax and walk away. Success now depends on clean data so AI knows what you sell and also knowing how to best leverage automation and algorithms, and when not to, while maintaining control over bids and placements. Businesses that pivot their approach and know the key levers will be the ones to see growth in 2026.

If you are still optimizing Google Shopping the same way and thinking of it as PPC, you are already late.

We are officially in the era of agentic commerce. We are entering a moment where the shopper is not always human. Decisions are being made by systems. And your brand now has to persuade an algorithm to be shown or suggested before it ever gets the chance to persuade a person.

Three weeks ago, on January 11th at the National Retail Federation (NRF) conference, Google announced the Universal Commerce Protocol (UPC), a new protocol designed to facilitate commerce using AI agents and enable agents to buy things online. It could mean that when you are having a chat on Google, an agent can find a product, suggest it, and allow you to buy it directly within the chat.

Feed and Data Quality Matter More Than Ever

Feed and data quality are becoming the most important factors for being discovered. Your feed quality, product titles, headlines, and product descriptions all help determine whether you are seen at all. You now need to front load how people and AI agents look for information.

Best practice is to organize product titles in the following order: Brand. Product name. Product category. Key variants. For example: Nike running shoes, black, size 6.

As AI pulls more information from your website, it is critical that your site has the right schema and metadata so systems can understand your products, offers, and other important details. In the era of AI, visibility will increasingly equal trust.

Performance Max vs Standard Shopping

This audio also covers tactics for structuring campaigns to get the biggest return on your spend. One key example is blocking brand terms from Performance Max campaigns so you do not overpay for traffic you would have likely captured anyway. Instead, put brand terms into a Standard Shopping campaign, use a manual CPC strategy, and set a lower cap to protect your brand.

When you are launching a new product or just starting out, Standard Shopping is often the better place to begin. It allows you to generate clean performance data that can later be used by Performance Max. PMax is only as strong as the data it has to optimize against.

Standard Shopping is a scalpel. You control bids. You decide which SKUs get attention. That level of control matters, especially for testing.

The Real Shift for 2026

Winning is not about turning on automation and walking away. It is about being an architect.

You supply clean, structured fuel. The AI does the driving.

In the age of agentic commerce, visibility is trust. And trust starts with data that is designed to convince machines first and humans second.

If that feels like a paradigm shift, it is. And it is already happening.
