Are you ChatGPT visible? 

Schema markup helps Google understand your product pages. But does it help AI platforms like ChatGPT or Gemini?

Sort of. The relationship is indirect but real. Schema doesn’t directly control your visibility in AI recommendations, yet it provides the structured signals that every platform depends on.

Schema Markup and AI Platforms

Gemini: Directly parses schema through Google’s systems. It’s the most schema-dependent of the AI platforms, since its Shopping Graph and Merchant Center both rely on structured markup.

ChatGPT: Doesn’t read your on-page schema directly, but Shopify’s Agentic Commerce Protocol (ACP) feed includes nearly the same data.

In short: good schema practices = good ACP feed data.

Perplexity: Crawls the web and uses schema for structural context. Moderate importance helps with clarity, but not the only signal.

Claude: Uses schema as part of its context when browsing the web. Helpful, but not essential.

The pattern: schema doesn’t hurt anywhere and helps almost everywhere. It’s worth doing properly.

Core Product Schema Elements

Make sure these are complete and accurate on every product:

• Product name
• Price and Currency
• Availability
• Image
• Brand

These are foundational for both Google Shopping and ACP-based feeds.

Contextual Attributes For AI Shopping

Add contextual attributes inside "additionalProperty", it’s the part of the Product schema that describes how and when a product is used:

"additionalProperty": [
  { "name": "Use Case", "value": "everyday office wear" },
  { "name": "Best For", "value": "sensitive skin" },
  { "name": "Occasion", "value": "casual Friday" }
]

‍

That additionalProperty field is often overlooked, yet it’s what lets AI systems understand intent, just as they interpret prompts like “What’s a good moisturizer for sensitive skin?”

Structured context like this directly improves visibility.

Beyond Schema: Building AI Context

Schema alone won’t make your products visible in AI shopping. But schema + complete feed + context-rich descriptions absolutely will.

Focus on three things:

1. Complete product data in your ACP feed.
2. Write descriptions that explain context, not just features. Your copy should help AI understand who the product is for and when it’s used. Our Prompt-Optimized Product Descriptions guide breaks down how to do this effectively. ‍
3. Also, include an llms.txt file for brand-level context, it helps AI systems grasp what your store is about before interpreting individual products.

A schema is a structure. Descriptions and feeds are meanings. Together, they make AI understand and recommend your products.

Shopify Schema Implementation Tips

Most Shopify themes already include basic Product schema. To add custom attributes, edit your theme’s product.json. Insert your custom "additionalProperty" attributes.

If editing code isn’t your preference, use a schema app or let the Atomz Catalog Agent automatically structure attributes.

For most merchants, the bigger ROI comes from fixing product descriptions and feed completeness before schema tweaking. Think of schema as polish; your data and descriptions are the foundation.

Bottom Line

Schema is no longer just for Google. It’s part of the broader AI Optimization (AIO) stack that helps large language models understand why your product matters. Implement it once, structure it well, and every AI platform from ChatGPT to Gemini will read your store more clearly.
