Claude reaches a store through ClaudeBot and Claude-User during web search, and favours pages that state product facts explicitly over pages that imply them, which makes description specificity and complete structured data the levers that matter most.
How Claude discovers and understands products
Search, then synthesise
Claude retrieves pages during web search and builds the answer from what it read. Content published after any training cutoff is still reachable, because the fetch happens at question time.
Distinct agents for distinct jobs
ClaudeBot handles indexing, Claude-User handles fetches made while answering a specific question, and anthropic-ai appears in older robots.txt guidance. Nomu checks all three.
Explicit beats implied
Claude is noticeably conservative about asserting things a page does not say. A specification stated in a sentence is usable; the same fact left to be inferred from a photograph is not.
A real question a shopper asks Claude
“a gift for someone with sensitive skin who dislikes strong fragrance”
An open-ended question with two soft constraints. It rewards pages that describe who a product suits, which most product copy never states.
Signals that may improve visibility
- ClaudeBot, Claude-User and anthropic-ai permitted in robots.txt
- Specifications written as sentences with units, not only as an image or a spec sheet graphic
- Product structured data that agrees with what the page visibly says
- Policy pages — shipping, returns, warranty — stated in prose that can be quoted
- An llms.txt or agents.md describing what the store sells and to whom
- No contradictions between your product page and third-party descriptions of the same product
These improve whether Claude 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 Claude today
Nomu probes Claude with your buying questions and records whether your domain appears. Clicks arrive with a referrer rather than a tracking parameter, so attributed revenue from Claude is a floor, not a total.
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 Claude can match it to a question.
Premium leather laptop bag. Stylish and durable.
Matches nothing — no attribute a buyer filters on.
A full-grain leather satchel with brass hardware and a padded sleeve that fits laptops up to 16 inches. Water-resistant, not waterproof. Weighs 1.1kg empty. Suits daily commuting; too structured to pack flat for travel.
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 Claude 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.
