LLM Visibility: Is Your Ecommerce Store Visible to AI?
AI search engines and shopping assistants are the new discovery channel for ecommerce. Check if your store is visible to LLMs like ChatGPT, Gemini, and Perplexity - or if you're invisible to AI-powered product discovery.
What We Check for LLM Visibility
AI Bot Access
robots.txt configuration for GPTBot, ClaudeBot, PerplexityBot, Googlebot-Extended, and other AI crawlers.
Content Accessibility
Whether your product content renders without JavaScript. Server-side vs client-side rendering detection.
Structured Data
JSON-LD Product schema, breadcrumbs, organisation data - the structured information AI systems parse.
Why LLM Visibility Matters for Ecommerce
The way people discover products is shifting. Millions of shoppers now ask AI assistants for product recommendations instead of - or alongside - traditional search engines. ChatGPT, Perplexity, and Gemini are becoming product discovery platforms.
Unlike traditional SEO, where you optimise for search engine crawlers and ranking algorithms, LLM visibility is about making your content understandable and accessible to AI systems that synthesise information differently. AI assistants don't just index pages - they need to understand your products well enough to recommend them.
Stores that are invisible to LLMs are missing a growing sales channel. The fix is often straightforward: correct robots.txt configuration, proper structured data, and server-rendered content.
Key LLM Visibility Factors
- ✓robots.txt - Ensure GPTBot, ClaudeBot, and PerplexityBot are not blocked. Many Shopify and WooCommerce themes add overly restrictive rules.
- ✓Server-side rendering - Product content must be in the initial HTML response, not loaded via JavaScript after page load.
- ✓JSON-LD Product schema - Complete structured data with name, brand, price, availability, description, reviews, and images.
- ✓Clean HTML structure - Semantic headings, proper alt text, and content that makes sense when extracted from the page.
- ✓llms.txt - An emerging standard that helps AI systems navigate your site. Early adoption gives you an edge.
- ✓Content depth - Rich product descriptions, specifications, and genuine reviews give AI more context for recommendations.

Frequently Asked Questions
What is LLM visibility for ecommerce?
LLM visibility refers to whether large language models (like ChatGPT, Gemini, Perplexity, and Claude) can discover, access, and understand your product pages. If your store has poor LLM visibility, AI assistants can't recommend your products when shoppers ask for purchasing advice.
How do I check if AI bots can access my store?
Enter your store URL in PageDiag's scanner above. We check your robots.txt for AI crawler rules (GPTBot, ClaudeBot, PerplexityBot, Googlebot-Extended), test whether your content renders without JavaScript, verify structured data accessibility, and check for llms.txt if present.
What is robots.txt and how does it affect AI visibility?
robots.txt is a file that tells web crawlers which pages they can and can't access. Many ecommerce stores inadvertently block AI crawlers by adding blanket Disallow rules for GPTBot, ClaudeBot, or using overly restrictive wildcard rules. If AI bots are blocked, your products won't appear in AI-powered search or shopping recommendations.
What is llms.txt?
llms.txt is an emerging standard (similar to robots.txt) that provides LLMs with a structured overview of your site - what it does, key pages, and how to interpret your content. While not yet widely adopted, early implementation signals to AI systems that your site is AI-friendly and provides helpful navigation context.
Does JavaScript rendering affect AI visibility?
Yes - most AI crawlers cannot execute JavaScript. If your product information, prices, reviews, or descriptions only load via client-side JavaScript (common with SPAs and some headless commerce setups), AI assistants can't see your content. Server-side rendering or static generation is essential for LLM visibility.
