The nine Shopify product feed fields that most decide whether AI recommends you are GTIN, brand, title, product type, condition, price, availability, color, and material. Get these right and an assistant can match your products to real requests. Leave them blank and you get skipped.
1. GTIN
The global identifier ties your product to a known catalog entry. Google's GTIN guidance treats it as a core trust signal. Missing GTINs make it harder for AI to confirm what you're selling.
2. Brand
Brand lets the model group and verify your products. Inconsistent brand values across your catalog read as noise and get discounted.
3. Title
Front-load the real product name with the attributes shoppers ask for. "Men's waterproof trail running shoe, size 11" beats a clever name an assistant can't parse.
4. Product type
Clear categorization helps AI place your item in the right comparison set. Vague types keep you out of the shortlist for specific queries.
5. Condition
New, used, or refurbished changes whether you match a shopper's request. A blank condition field forces the model to guess, and it often guesses against you.
6. Price
Price has to be live and correct. The Offer schema carries it for exactly this reason. Stale price is a fast way to lose trust.
7. Availability
If your feed says in stock and the item is gone, any assistant that recommends it looks wrong. It learns to stop trusting your availability signal.
8. Color
Standardize it. "Blue" everywhere, not "navy," "BLU," and "001" across three products. Consistent values are what let AI filter "blue ones under fifty dollars."
9. Material
Material powers a surprising share of specific requests. Shoppers ask for cotton, leather, stainless steel. A blank material field keeps you out of those answers.
How we chose this list
These nine come straight from the fields AI shopping surfaces read and the attributes Google's product data spec requires. They're the fields most often left blank on the stores that stay invisible.
Frequently Asked Questions
Which feed field matters most for AI?
GTIN is a core trust signal because it ties your product to a known catalog entry an assistant can verify.
Why does a blank field hurt more than a short one?
A blank required field signals an unmaintained catalog, which lowers trust in the entire feed.
How consistent do my values need to be?
Very. The same color should mean the same thing everywhere so AI can filter requests like blue ones under fifty dollars.
