How to Make Your Product Feed Discoverable in ChatGPT

If you want your products to show up in ChatGPT’s shopping and discovery experiences, you’ll need to set up a product feed that matches OpenAI’s official spec. Don’t worry — while the spec looks technical, once you break it down, it’s not too different from filling in a structured spreadsheet about your products.

This post walks through what a product feed is, why it matters, and exactly what information to include.

1. What’s a Product Feed?

Think of a product feed as a structured catalog. Each row is a product, each column is an attribute like ID, title, price, or image. OpenAI uses this feed to understand what you sell and how to display it inside ChatGPT.

If your feed is complete and accurate, your products are more discoverable, and customers can even buy them directly inside ChatGPT (if you enable checkout).

2. Why This Matters

• Discoverability: Without a proper feed, ChatGPT won’t know your products exist.

• Better Shopping Experience: More details = richer displays. Products with images, reviews, and variants stand out.

• Eligibility for Checkout: If you want in-app checkout, certain fields (like price, shipping, and inventory) must be filled.

• Control: You decide what gets surfaced (via flags like enable_search and enable_checkout).

3. What Information Goes in the Product Feed

Your product feed is basically a structured spreadsheet where each product has a row and each attribute (ID, title, price, etc.) is a column. OpenAI’s spec defines exactly what you can include, what’s required, and how to format it.

Here’s a breakdown of the most important fields, combining the official spec details with plain-English explanations and examples.

Takeaway: Fill out every required field, but don’t stop there. The more “recommended” and “optional” fields you supply (reviews, categories, images, variants), the better ChatGPT can showcase your products.

4. Best Practices

• Keep data fresh: Update inventory, pricing, and availability regularly.

• Use real product images: Don’t rely on placeholders or logos.

• Include rich attributes: Size, color, material, reviews — these help your products stand out.

• Test your feed: Validate links, check that product pages load, and confirm formatting (especially dates and prices).

5. Wrapping Up

Making your product feed discoverable in ChatGPT is mostly about being structured and complete. Once your feed is properly set up, ChatGPT can surface your products more effectively and even enable direct checkout.

If you treat the feed like your storefront window — clear, detailed, and accurate — you’ll be better positioned to capture attention in this new shopping channel.
