AI shopping assistants weigh a short list of product attributes heaviest when they decide which Shopify products to recommend. These ten are the ones that matter most in 2026. Get them complete and accurate and you give ChatGPT, Perplexity, and Google AI Overviews every reason to name you.
Here's the bottom line. The assistant matches the shopper's question against your fields. Thin fields, no match.
1. Title
The title is the first match. Write it the way a shopper asks, with the key feature and use case up front, not an internal product name.
2. Unique identifier (GTIN/MPN)
Identifiers let the assistant confirm the product is real and cross-reference it. Google's product data spec treats these as core fields for a reason.
3. Price
Budget is in almost every shopping query. Accurate price lets the assistant filter you into "affordable" or "premium" correctly. A mismatch with your store price erodes trust fast.
4. Availability
Assistants avoid recommending out-of-stock items. A live, accurate availability field keeps you in the running instead of silently dropped.
5. Product category
Category places you in the right comparison set. Wrong category, wrong shelf, and the agent never sees you next to your real competitors.
6. Attributes (color, size, material, fit)
These are the filters inside the query. "Waterproof," "wide fit," "merino" all need a field to land on. Fill them in and you match specific, high-intent questions.
7. Description
A substantive description, 40 to 200 words, gives the assistant language to quote and details to match. Thin copy gives it nothing.
8. Reviews and ratings
Trust signals break ties. Mark reviews up with AggregateRating schema so the machine can actually read them, not just show them to humans.
9. Image
A working, clear image link signals a complete listing. Assistants favor complete records, and some surfaces show the image directly in the answer.
10. Brand
Brand ties your products together as a consistent entity. Standardize it across your feed and schema so the assistant recognizes you as one coherent store.
How to use this list
Score your top 20 products against these ten fields. Every blank is a lost match. Fill identifiers, titles, and attributes first, then confirm the live page carries the same data with Product schema.
Frequently Asked Questions
Which product attribute matters most to AI?
The title, because it is the first thing the assistant matches against the shopper's query. Write it the way people ask, with the key feature and use case up front.
Do reviews really affect AI recommendations?
Yes, as a trust signal that breaks ties, but only if they are marked up with AggregateRating or Review schema so the machine can read them.
How do I check which attributes I'm missing?
Score your top products against these ten fields. Every blank field is a query you can't match. Fill identifiers, titles, and attributes first.
