AI visibility
Every assistant reads your store differently.
Each one uses its own crawlers, weighs different signals, and exposes a different amount of evidence about what it did. These pages cover what each reads from a Shopify store, what Nomu audits for it, and where Nomu’s measurement stops.
| Assistant | Crawler checked | Citation probes | Attribution |
|---|---|---|---|
| ChatGPT | GPTBot, OAI-SearchBot, ChatGPT-User | Yes | Link parameter |
| Claude | ClaudeBot, Claude-User, anthropic-ai | Yes | Referrer |
| Google Gemini | Google-Extended | Yes | Not separable |
| Perplexity | PerplexityBot, Perplexity-User | Yes | Referrer |
| Microsoft Copilot | — | Not yet | Referrer |
| Grok | — | Not yet | Referrer |
| Meta AI | Meta-ExternalAgent | Not yet | Referrer |
Nomu’s site audit checks 14 AI crawlers and applies to every assistant here. Citation probes exist for four engines today; where they do not, the page says so rather than implying coverage.
ChatGPT
ChatGPT answers shopping questions by fetching pages at the moment of the question. Nomu checks whether it can reach your store, whether your products answer a buying question, and whether it names you when asked.

Claude
Claude reads pages during web search and tends to prefer sources that state their facts plainly. Nomu checks whether it can reach your store, whether your products answer a question, and whether it cites you.

Google Gemini
Google-Extended is a separate control from Googlebot, so a store can rank respectably in Search while being invisible to Gemini. Nomu checks that directive first, then everything downstream of it.

Perplexity
Every Perplexity answer names the pages it drew on, so your category's winners are readable directly. Nomu probes it with your buying questions and records who gets cited when you do not.
Read the guideMicrosoft Copilot
Copilot grounds its answers in Bing's index, so the work that makes a store readable to any assistant applies. Nomu audits that groundwork — and does not yet measure Copilot citations, which this page says plainly.

Grok answers using current web and platform content. Nomu audits the groundwork that makes a store readable to any assistant — and does not yet run citation probes against Grok, which this page states plainly.

Meta AI
Meta AI runs inside Instagram, WhatsApp and Facebook — the surfaces many Gulf merchants sell on daily. Nomu checks its crawler directive and audits the content it would read, and does not yet probe it for citations.
