ChatGPT recommends products by retrieving live pages rather than recalling training data, so a Shopify store becomes eligible by permitting OpenAI's crawlers, stating product facts explicitly, and publishing complete Product structured data.
How ChatGPT discovers and understands products
It fetches, then answers
For product questions ChatGPT performs a live retrieval step — issuing searches and reading pages seconds before it replies. A product you published this week can be recommended this week.
Three separate crawlers
GPTBot for indexing, OAI-SearchBot for search results, and ChatGPT-User for fetches made on behalf of a specific question. They are permitted independently in robots.txt, and blocking one does not block the others.
It has to defend the answer
Recommending a product is a claim. Where a page states a fact plainly, the answer is safe to give; where the fact must be guessed, a competitor's clearer page tends to win instead.
A real question a shopper asks ChatGPT
“best unscented shampoo for a sensitive scalp under $30”
Three constraints — unscented, sensitive scalp, under $30. Your page either satisfies each explicitly or fails the filter silently.
Signals that may improve visibility
- GPTBot, OAI-SearchBot and ChatGPT-User permitted in robots.txt — and not blocked by a CDN bot rule before the request reaches Shopify
- Product descriptions that state the attributes buyers constrain on, with numbers and units
- Complete Product structured data — price, priceCurrency, availability and brand, per variant
- Server-rendered content, so nothing important depends on client-side JavaScript
- Shipping, returns and sizing stated in plain sentences rather than inside a collapsed accordion
- Consistent facts across your own pages and third-party listings, so there is no contradiction to resolve
These improve whether ChatGPT can read and verify your products. No tool can guarantee that an assistant recommends you — answers are non-deterministic and no vendor sells placement in them.
What Nomu measures for ChatGPT today
Nomu asks ChatGPT your buying questions on a schedule and records whether your domain appears. Answers are non-deterministic, so the trend across a fixed question set is the signal — never a single run.
What Nomu can detect
The audit runs nightly and reports only what it can prove.
AI crawler blocked in robots.txt
criticalAn assistant's crawler is disallowed, so nothing else about the store can matter to it. Binary, and the first thing checked.
No llms.txt or agents.md
mediumNo plain-language guide to what the store sells, so the catalogue has to be inferred by crawling.
Product structured data missing or incomplete
highPrice, currency, availability or brand absent, so a hard constraint like "under $30 and in stock" cannot be verified.
Product descriptions too thin to answer a question
highDescriptions that state a name and a size answer no buyer constraint, so the product is retrievable for nothing.
Titles, meta descriptions or image alt text missing
mediumThe fields that tell a crawler what a page and its images are, left empty.
No FAQ or policy page an assistant can quote
mediumShipping, returns and sizing questions have no answerable page to cite.
Collection pages with no descriptive text
lowCategory pages that list products without saying what the category is or who it suits.
What a fix looks like
The same product, rewritten so ChatGPT can match it to a question.
Amber Oud 50ml. Long lasting.
Matches nothing — no attribute a buyer filters on.
A hand-poured amber oud built on warm resin, vanilla and a dry cedar base. Alcohol-free and unscented at the base, so it suits sensitive skin. Expect 8+ hours of wear. Unisex. The 50ml bottle is refillable.
Nomu drafts the rewrite from your own product data. Nothing publishes until you approve it, and every change is reversible for 30 days.
Fixes Nomu can generate
Rewrite a product description
Drafts a description built from the attributes buyers filter on — material, fit, use case, care — from your own product data.
Fill in title, meta description and image alt text
Generates the SEO fields a product is missing, per product, for your approval.
Add Product structured data
Emits schema.org Product markup with price, currency, availability and brand populated per variant.
Create an FAQ page
Builds an FAQ from your real policies and the questions your customers actually ask.
Publish llms.txt
Writes a plain-text guide describing what you sell, to whom, and which pages are canonical.
Write a collection description
Describes what is in a category and who it suits, so the collection page can be retrieved.
Tracking improvement over time
Nomu asks ChatGPT your buying questions on a schedule.
The question set stays frozen between runs, because changing it would void the comparison. Nomu records whether your domain appears, which competitors appear instead, and how that moves after a fix — reported as a trend, never as a single run.
