What is llms.txt and why does my site need it?

llms.txt is the new robots.txt for AI. It tells AI agents like ChatGPT, Claude, and Perplexity what your site is about, what products you sell, and how to navigate your content. Without it, AI shopping agents may not recommend your products to users.

Why does structured data matter for AI agents?

AI agents parse structured data (JSON-LD schema markup) to understand your products, prices, availability, and reviews. Without Product, Offer and AggregateRating markup an assistant has to infer those fields from prose, and a field it cannot read is a field it cannot match a query against. No published study quantifies the size of the effect, so this scanner reports which markup is present rather than a predicted uplift.

What schema types should an ecommerce site have?

At minimum: Product (with Offer), Organization, WebSite, and BreadcrumbList. Recommended additions: FAQPage, AggregateRating, Review, and Brand. Each schema type helps AI agents understand a different aspect of your business.

What is agentic commerce?

Agentic commerce is when AI agents (like ChatGPT, Perplexity, or Google's AI) act as shopping assistants for consumers. Instead of browsing websites, users ask AI agents to find products. If your site isn't structured for AI, these agents can't recommend you. That makes you invisible to a growing segment of shoppers.

How do I improve my AI readiness score?

Add Product schema with complete fields (name, description, price, availability), create an llms.txt file, add Organization schema, ensure Open Graph tags are complete, and add a sitemap.xml. Our scanner generates copy-paste code for everything you're missing.

Fetches the page, parses HTML for JSON-LD blocks and meta tags, checks /llms.txt and /llms-full.txt, scores against a checklist of agent-readable signals (Product, Organization, WebSite, BreadcrumbList, FAQPage, llms.txt, sitemap, OG tags).

Agent readability is one of seven checks in the full growth audit. The same run also reads your tracking, your public catalogue, your landing page and whether ChatGPT and Claude name you when asked what you sell.
