How AI shopping assistants decide which products to recommend

A growing share of shopping starts as a question to an AI assistant: "find me a good rain jacket under 200." The assistant does not browse your store the way a person does. It does not watch your hero video or feel your brand. It reads data.

The visit looks like this

HOW AN AI ASSISTANT SHOPS"find me a good rain jacket under 200"the assistant reads each store's machine data:store A: name, GBP 179, in stock, 4.7 stars (2,310 reviews)store B: name. (no price, no stock, no rating)it does not scroll, squint, or guess. data or nothing."Store A's jacket is 179, in stock, rated 4.7 by 2,310 buyers.""Store B also sells jackets."which store gets the sale?five of six big Shopify stores we checked this week were store B

What assistants actually read

Three things, all of which you control:

  • Your product data. The same hidden label Google reads: name, price, stock, ratings. We checked six big Shopify stores this week - five send no ratings. To an assistant, those products are half invisible.
  • Your agent instructions. Shopify now serves a page of instructions for AI agents on every store, automatically. Most merchants do not know it exists, and it only works well when the product data behind it is complete.
  • Your page structure. Assistants find their way around by the names of things, like a screen reader does. A store full of unnamed buttons is a store an agent cannot operate.

Nobody blocks the assistants anymore

A year ago the debate was whether to let AI crawlers in. That is settled: the big, well-run stores we checked explicitly allow every major AI agent, and Shopify's defaults do too. The traffic is coming either way. The open question is what the assistant finds when it arrives.

Getting picked

When an assistant compares ten stores, it recommends the ones it can describe with confidence: a price, a stock status, a rating from real buyers. That is not marketing. It is data plumbing, and it is the same plumbing that puts stars in Google:we wrote up what six big stores send, and what is missing.

If you want to know what an assistant sees on your store, ask us. We will read your store the way an agent does and send you the transcript, free.

Correction, October 2026: an earlier version said some of these stores send no price. They do. Stores with sizes or colours put the price on each variant, which is the format Google recommends, and our first reader only looked at the top level. The ratings finding is unaffected.
