Google's New Conversational Attributes Schema Is Live — And Your Shopify Product Descriptions Don't Qualify Yet

By Steve Merrill, Founder of WRKNG Digital — June 25, 2026

Google shipped Conversational Attributes in Merchant Center in early 2026. Most Shopify stores aren't ready. Not even close.

This isn't a problem coming down the road. AI Mode is live now in the US, embedded directly in Google Search. It surfaces products in chat-style answers to context-heavy queries. And it pulls from a specific set of feed attributes that the vast majority of Shopify stores have never populated.

If your store is one of them, you're already invisible to a growing share of AI-driven shopping queries. Here's what's happening and what to do about it.

What Are Google's Conversational Attributes for AI Mode?

Conversational Attributes are a set of structured product data fields Google added to Merchant Center specifically for AI Mode — the chat-style search experience now live inside Google Search. They tell Google's AI how to match your products to natural language queries like "What's a good running shoe for someone with wide feet under $120?"

The standard product feed format was built for keyword matching. A user types "running shoes," Google returns results based on title relevance, price, and review count. AI Mode works differently. It processes conversational, context-heavy questions and needs to understand who a product is for and when someone would use it — not just what it is.

According to Google's Merchant Center documentation on product attributes, the primary Conversational Attributes include product_highlight, product_detail, and lifestyle_image_link. These aren't brand-new feed fields — Google introduced some of them years ago — but AI Mode made them matter in a way they didn't before.

What Does the Schema Actually Require?

Four categories of structured data. Most standard product descriptions include none of them in the format AI Mode can use.

product_highlight: Short, factual bullet points about the product. Not marketing copy. Google's feed specification states explicitly that these should be "factual statements about the product, not opinions or promotional language." Most Shopify product descriptions are built almost entirely around brand voice and marketing claims.

product_detail: Attribute/value pairs. "Material: Merino wool." "Weight: 8 oz." Structured, machine-readable data that sits separate from your description prose. The moment you bury specs inside a paragraph, you've already lost the structured data battle.

Contextual use-case framing: Who is this product for, and in what situation would they use it? AI Mode answers context-heavy queries. If your feed doesn't explain that your jacket works for shoulder-season hiking, the AI can't match it to "I need a light jacket for fall trail runs." The AI won't guess. It'll surface a competitor whose data answers the question.

lifestyle_image_link: A product image showing it in use. Not a white-background studio shot. Google's AI Mode gives preference to images that show context — someone wearing the jacket, not the jacket alone on a white plane. Most Shopify product photography workflows produce exactly the wrong image type for this field.

Why Do Standard Shopify Descriptions Fall Short?

They were written for a different job entirely. Standard Shopify descriptions exist for humans who are already on your product page, already considering a purchase. They weren't built for an AI deciding whether to mention your product to someone who hasn't visited your site yet.

I've run Merchant Center feed audits on 50+ Shopify stores across apparel, outdoor gear, home goods, and beauty. The structure is almost always the same. A paragraph of brand voice at the top. Four to six bullet points covering specs. A sizing note or care instructions at the bottom. Maybe a CTA.

That's a fine format for converting browsers into buyers. It tells Google's AI almost nothing useful about when and why someone should buy the product.

The specific gaps I see most often:

• No product_highlight fields in the Google feed — only about 18% of stores I've audited have them populated at all
• Product details written as prose sentences instead of structured attribute/value pairs
• Zero lifestyle images submitted to the Merchant Center feed — only white-background product shots
• Descriptions that answer "what is this product?" but not "who is this for and when would they use it?"

Shopify's default product template doesn't push structured use-case context to your Google feed automatically. The Shopify Google & YouTube channel app supports some of these fields — but only if you've mapped them deliberately. The out-of-the-box setup gives Google the basics. Nothing more.

How Do You Fix This for Your Shopify Store?

Start with your top 20%. Not 2,000 SKUs at once.

Best-sellers and highest-margin products first. Those are the ones where AI Mode visibility will move the needle. Fix those before you touch the long tail.

Step 1: Audit your current Merchant Center feed. Log into Google Merchant Center, go to Products > All Products, and filter for items with quality improvement suggestions. Google will flag missing product_highlight fields and incomplete structured details directly in the dashboard. That's your starting hit list.

Step 2: Add product features in Shopify. The Google & YouTube sales channel supports product_highlight via the "Product Features" field inside Shopify's product editor. You can also create custom metafields in Shopify and map them to product_highlight in your feed configuration. Google's Search Central documentation on product structured data confirms that product_highlight accepts 2 to 10 bullet points per product, each under 150 characters. Keep them factual.

Step 3: Rewrite contextual descriptions for your top products. The goal is to answer one question well: "Who uses this, and in what situation?" Write that answer. Then extract the factual statements and move them into product_highlight fields. What remains in your description can stay as brand copy — but the structured data needs to live separately.

Step 4: Add lifestyle images to your feed. You don't need to reshoot your entire catalog. Pick your top 20 products. Find existing on-model or in-use shots. Add them as lifestyle_image_link entries in your feed. That alone will move the needle for AI Mode image matching.

If you're running a supplemental feed through Feedonomics or DataFeedWatch, you can layer in missing attributes without rebuilding your main feed from scratch. Both tools support product_highlight and product_detail as mappable fields, which makes this process much faster for larger catalogs.

What Happens If You Don't Update Your Feed?

Your competitors will be recommended. You won't.

According to Google's own reporting, AI Overviews now appear in more than 15% of all US search queries. Shopping-intent queries in AI Mode pull directly from structured Merchant Center data. Products that match the Conversational Attributes schema surface in those answers. Products that don't get passed over — regardless of how good they actually are.

There's a compounding effect here that I've watched play out with every major Merchant Center update over the past five years. Stores that adapt early capture visibility. That visibility drives sales. Those sales generate reviews and engagement signals. By the time late movers update their feeds, the early movers have lapped them on every signal Google uses to rank products in AI responses.

The window isn't closed. But it narrows every week more stores update their feeds and more AI Mode queries get answered by someone else's products.

Frequently Asked Questions

Are Conversational Attributes required or optional in Google Merchant Center?

Currently optional, but Google recommends them for AI Mode visibility. Products with complete Conversational Attributes are significantly more likely to surface in AI Mode shopping responses than products with only the baseline required attributes. "Optional" won't stay that way as AI Mode matures and more advertisers fill in the schema.

Does updating Conversational Attributes affect my standard Google Shopping ads?

Standard Shopping ads run off the same base feed. Conversational Attributes are additive — they don't replace existing required fields, they layer on top. Filling them in can also improve your listing quality score, which can affect both AI Mode visibility and standard Shopping ad performance.

Can Shopify automatically generate these attributes?

Not automatically. Shopify's product template doesn't write AI-friendly contextual descriptions or structured highlights on its own. You can use AI writing tools to draft them faster at scale, but the structured fields need to be mapped from Shopify metafields to your Google feed manually or through your feed management tool. There's no push-button fix.

How many product_highlight bullets should each product have?

Google's spec allows 2 to 10 per product. Four to six is the practical sweet spot. Each should be a factual, specific statement. "Waterproof up to 20 meters" works. "The best dive watch on the market" won't help you in an AI-generated answer because the AI can't verify or use a claim like that to match your product to a query.

What if I'm using a third-party feed tool like Feedonomics?

Most enterprise feed tools support Conversational Attributes as custom attribute mapping. Feedonomics and DataFeedWatch both support product_highlight and product_detail as mappable fields. Check with your tool's support team for their current attribute library. The mapping work is straightforward once you know which metafields in Shopify you're pulling from.

Want to Know Exactly Where Your Store Stands?

Most Shopify stores have significant gaps in their Merchant Center data for AI Mode. I built a tool specifically for this — it audits your product feed against the Conversational Attributes schema and shows you exactly which products are visible to AI Mode and which ones aren't. No guessing.
