The feed fields AI reads most are title, price, availability, GTIN, and brand, the facts it needs to match and trust your product. Here are the ten that decide whether AI can recommend you.
AI assistants read structured feed data before they read your site. Every blank field is a product they can't confidently surface.
1. Title
The title carries the search match. A vague title never lines up with what a shopper asks for, so the assistant never connects the two.
Write titles the way buyers describe the product, not the way your catalog codes it.
2. Description
The description is where AI confirms what the product actually is and who it's for. Thin or keyword-stuffed text gives it nothing to work with.
State the specifics plainly. Specificity is what gets matched to a real query.
3. Price
Price decides eligibility. AI won't recommend an item whose price it can't confirm, and it cross-checks the feed against your Offer markup.
Keep it accurate and consistent everywhere it appears.
4. Availability
Stock status tells the assistant whether the item can actually ship. Stale availability breaks trust and gets your data dropped.
Sync it to real inventory so it's true at the moment the agent reads it.
5. GTIN
The GTIN is how an assistant confirms your item is the exact product in question. Without it, matching becomes a guess.
Fill it per the Google Merchant spec wherever a product has one.
6. Brand
Brand helps AI place your product against branded queries and comparisons. A blank brand field makes you invisible to those searches.
Populate it consistently across the whole catalog.
7. Product category
Category tells the assistant where your product fits, so it surfaces in the right comparisons instead of the wrong ones.
Use the standard taxonomy values, not your internal labels.
8. Image link
A working, high-quality image link supports the recommendation and confirms the product visually. Broken images undercut trust.
Check that every image URL resolves and shows the actual item.
9. Condition
New, used, or refurbished matters to both shoppers and agents. A missing condition field can drop you from filtered results.
State it explicitly so the assistant can match intent.
10. Shipping details
Shipping cost and timing in the feed let an agent complete its comparison. Hidden shipping stalls the decision.
Follow the product data guidelines and state shipping as clear values.

Frequently Asked Questions
Which product feed fields do AI shopping assistants read?
AI leans hardest on title, description, price, availability, GTIN, and brand to match and confirm a product, plus category, image link, condition, and shipping details to place and complete the recommendation. Blank or wrong values in any of these reduce the odds AI surfaces your product.
What happens if my feed fields are blank?
Blank fields make products invisible or unmatchable. A missing GTIN or brand stops AI from confirming the exact item, a vague title breaks the search match, and stale price or availability gets your data distrusted. Each gap quietly costs recommendations you never see.
How many feed fields do I really need to fill?
Fill every field the Google Merchant specification asks for, but prioritize title, description, price, availability, GTIN, and brand first. Those decide eligibility and matching. Do them on your best sellers before working through the long tail of your catalog.
