Do you sell products online? Have you taken a fresh look at how your Google Shopping setup is performing in the last six months? If not, this article is for you.
A lot has shifted. Some of the changes are technical and easy to miss. Some of them quietly affect every dollar you spend on Google Shopping ads. And a few of them are genuinely exciting for small and mid-sized ecommerce businesses that have always felt like they were competing on uneven ground against the big retailers.
This is meant to be a friendly walkthrough. No gatekeeping, no overhyped jargon. We have managed Google Shopping campaigns for clients across dozens of ecommerce categories over the last 11 years from our Chicago and Westminster offices, and we want to give you the practical picture of where things stand right now.
If you sell physical products in the US or Canada and run any Google Shopping ads, here’s what you need to know for 2026.
The Big Picture: Google Shopping Is Now an AI-Driven System
Let’s start with the headline. Google Shopping in 2026 is not the same product comparison engine it was a few years ago. It is now a fully AI-driven commerce ecosystem, and the way your products get discovered has fundamentally changed.
Here is what that means in plain terms:
What Has Changed: The Key Updates You Should Know About
Change 1: Merchant Center Next Is Now the Only Version
Google Merchant Center Next is the redesigned interface for managing your product feeds and Shopping ads setup. Google completed the migration of all merchants to Merchant Center Next by October 2024, so if you have an active Merchant Center account today, you are using it whether you noticed the change or not.
What is different about it compared to the older interface:
For most SMBs, this is a positive change. The setup is faster, the diagnostics are easier to read, and the day-to-day management requires less digging.
Change 2: New Product Data Attributes Rolling Out in 2026
Google announced several updates to its product data specification that affect what you can and should include in your feed. These changes phase in across April 14, 2026, June 30, 2026, and January 31, 2027.
Here are the ones that matter most for SMB ecommerce.
New shipping attributes at the product level (April 2026):
These are useful if you have variable shipping rules. If you ship everything the same way, you can ignore them for now.
New optional video attribute (April 2026, with serving starting June 2026):
For most small ecommerce businesses, this is an opportunity. Video on product listings tends to outperform photo-only listings for engagement, and the merchants who add product video early will likely benefit as the feature matures.
Updated image size requirements (warnings starting April 2026, enforcement January 2027):
Google is raising the minimum image resolution to 500 by 500 pixels across all product categories and marketing methods. Images smaller than that will start getting warnings, and eventually products with undersized images will be disapproved.
If your product photos are smaller than 500×500, this is the year to upgrade them. For most categories, 800×800 or larger is the actual sweet spot, and Google has indicated 1500×1500 is a recommended target for the best display across all surfaces.
Change 3: Performance Max Now Competes with Standard Shopping on Equal Footing
This one slipped under the radar for a lot of advertisers, and it is worth understanding clearly.
For years, when you ran both a Performance Max campaign and a Standard Shopping campaign that included the same products, Performance Max automatically won the auction. The system gave PMax priority no matter what.
Google changed that in late 2024. Now, Performance Max and Standard Shopping campaigns compete based on Ad Rank, which is essentially the combination of your bid and Google’s prediction of how likely the ad is to perform well.
Why this matters for SMBs:
We will get into specific hybrid strategies later. For now, just know that the door has opened on a lot of tactics that used to be theoretical.
Change 4: Free Product Listings Are Still Free & Still Underused
Google’s free product listings have been around since 2020, but a surprising number of SMB ecommerce owners we talk to do not realize their products can show up in Google’s free shopping results without spending anything on ads.
When you have a Merchant Center account with an approved product feed, your products automatically become eligible to appear in:
You do not have to do anything extra to enable this beyond having a clean, approved feed. The same product data that powers your paid Shopping ads also powers the free listings.
If you have been thinking about Shopping ads but have not pulled the trigger because the budget feels intimidating, free listings are a no-risk way to get visibility. The trade-off is that paid listings get better placement and priority, especially on competitive queries.
Change 5: AI Mode Is Reshaping Where Shopping Ads Appear
Google AI Mode (the conversational AI version of Search) is now showing sponsored shopping results in line with its AI-generated answers. When a shopper asks “what is the best espresso machine for under $500,” AI Mode might surface organic recommendations and then show sponsored retailer offers clearly marked as ads.
What this means practically:
You do not need a separate AI strategy to start. You need a complete, accurate, well-described feed. The merchants whose feeds are best optimized will get pulled into AI Mode results more often, with better positioning.
Change 6: Amazon’s Shifting Presence on Google Shopping
If you sell to Canadian customers, this one is worth knowing. After years of being a major presence on Google Shopping, Amazon pulled back significantly from the platform in mid-2025, briefly leaving most markets, then began returning to international markets including Canada and Europe in August 2025. Amazon’s presence in US Shopping ads has been more variable, with the company adjusting its investment levels in ways that have shifted the competitive landscape repeatedly.
For Canadian SMBs in particular, the practical responses we have seen work:
What Still Works: The Fundamentals That Drive Shopping Ad Success
Now for the part most SMB ecommerce owners actually need to hear. The fundamentals that drove Shopping ad performance three years ago still drive it today. Most of the businesses we audit are losing money not because they failed to adopt the newest feature, but because they are missing one or more of these basics.
Fundamental 1: Your Product Title Is the Single Most Important Field
If you do one thing after reading this article, look at your product titles.
Product titles carry more weight than any other attribute in your feed. They determine which searches your products match, how they appear in results, and how Google’s AI categorizes them.
The structure that consistently works:
For physical goods: Brand + Product Type + Key Feature + Color + Size + Material
Examples that work well:
Examples that hurt your performance:
Many merchants who restructure their titles see meaningful lifts in impressions and click-through rate. This is one of the highest-leverage changes available to you, and it costs nothing but the time to do it.
Fundamental 2: Get Your GTINs Right
A GTIN is the Global Trade Item Number that identifies a product across retailers. UPC codes, EAN codes, and ISBN numbers are all forms of GTINs.
Why GTINs matter:
If you sell branded products (Nike, Apple, KitchenAid, etc.), the manufacturer almost certainly assigned a GTIN to each product. You can usually find it on the box, on the manufacturer’s website, or by searching the model number on a GTIN lookup service.
If you sell your own branded products (private label, custom-made, handmade goods), you can apply for GTINs through GS1 in the US or Canada. The application is straightforward and the GTINs become permanent identifiers for your products.
If you sell vintage, antique, or one-of-a-kind items that genuinely do not have a GTIN, you can set the identifier_exists attribute to “no” and skip the GTIN field. But do not abuse this for branded products. Google’s systems are good at catching it, and the resulting disapprovals are painful to recover from.
Fundamental 3: High-Quality Product Images Are Still a Conversion Lever
The basics that still apply:
The new image resolution rules we covered earlier (500×500 minimum starting January 2027, with warnings starting April 2026) make this an especially good year to upgrade any old, undersized product photography.
For SMB ecommerce businesses without a photography budget, smartphone cameras in 2026 are good enough for clean white-background product shots if you have decent lighting. The improvement in performance from upgrading bad photos almost always pays for itself within the first 30 days.
Fundamental 4: Product Descriptions Should Actually Describe Products
This sounds obvious, and yet it is one of the most consistently neglected fields.
Google uses your product description for two things: matching your product to long-tail searches, and feeding AI-driven results that summarize your product’s features. A weak description hurts both.
What works:
What hurts:
If you have hundreds of SKUs and writing descriptions feels impossible, AI tools like ChatGPT, Claude, or Google’s own Gemini can draft descriptions in bulk if you feed them your product specs. The results are not perfect, but they are infinitely better than blank or duplicated descriptions, and they give you a starting point to refine.
Fundamental 5: Use Custom Labels for Smart Segmentation
Custom labels are five optional fields in your product feed (custom_label_0 through custom_label_4) that you fill in with whatever categorization you want. Google does not show these to shoppers. They exist purely so you can organize your campaigns the way you want.
Smart ways to use custom labels:
The benefit shows up when you want to run a Standard Shopping campaign that only targets your highest-margin products, or when you want to exclude clearance items from your evergreen Performance Max campaign. Without custom labels, you cannot easily do this. With them, segmentation becomes a few clicks.
Fundamental 6: Price & Availability Must Match Your Website Exactly
This sounds basic but it is the single most common reason for product disapprovals.
When your feed says a product costs $79.99 and your website displays $89.99, Google will disapprove the listing. When your feed says a product is “in stock” but the website shows “sold out,” same outcome.
Solutions:
The cost of getting this wrong is not just disapprovals. Google deprioritizes accounts with chronic feed inaccuracies, which means lower placement and higher CPCs across your entire catalog.
The Hybrid Strategy That Works for SMB Ecommerce
Since Google opened up the auction so Performance Max and Standard Shopping can compete fairly, a specific strategy has emerged that works well for many SMB ecommerce businesses.
The structure looks like this:
Performance Max as your primary engine: This runs across your full catalog and handles the bulk of your reach. Google’s AI optimizes for the highest-conversion opportunities across all the surfaces (Search, YouTube, Discover, Gmail, Display).
Standard Shopping as a tactical overlay for specific situations PMax handles poorly:
This hybrid approach is more involved than just running PMax and walking away, but in our experience, it gives most SMB ecommerce accounts noticeably better blended ROAS than a PMax-only setup.
Common Mistakes We See Most Often
We audit a lot of Shopping accounts. Here are the most common mistakes:
Where to Start If You Are Starting from Zero
If you are reading this and realizing you have some catching up to do, here is a practical 30-day plan.
Week 1: Audit your feed
Week 2: Fix the basics
Week 3: Improve your campaign setup
Week 4: Add the strategic layer
This is the same workflow we use for new ecommerce clients during their first month with us. It is not glamorous, but it consistently moves accounts from barely working to actually profitable.
Google Shopping Needs Attention. We Can Help.
Google Shopping in 2026 rewards merchants who treat their product data like a real asset. Not a one-time setup. Not something to bolt on. Something to maintain and improve, the same way you maintain your website or your customer service.
The good news for SMBs is that most of your competitors are not doing this work. We see it every day. Stores with 200 products and zero filled-in attributes beyond what their ecommerce platform automatically generates. Titles that read like database entries. Photos shot under fluorescent office lighting against a beige wall.
If you want a fresh pair of eyes on your feed, we offer a free Shopping ads and Merchant Center audit for ecommerce SMBs in the US and Canada. You can reach us at (773) 419-3636 or by scheduling a consultation through our Google Advertising service page.
