LLM.txt & AI Crawler Setup Guide for Marketplace sellers

Create a text file at /ai.txt with a brief introduction to your seller identity and core product categories.

Include markdown-style links to your most important product listing templates, policy pages (returns, shipping), and seller performance metrics.

Add an 'FAQ' section within the file to directly address common queries AI agents might have regarding your fulfillment, product variants, or unique selling propositions.

Verify your crawler permissions using marketplace-provided tools or by observing bot behavior in server logs.

Monitor crawl frequency and request patterns in your server logs to ensure marketplace AI bots are accessing optimized product data and seller information, not administrative sections.

Wrap your primary product details (name, price, brand, SKU, GTIN) within structured data markup (e.g., JSON-LD for Product schema) to ensure precise extraction.

Use semantic HTML tags like <section> with descriptive 'data-label' attributes for distinct product features, benefits, or technical specifications.

Ensure all product variant information (size, color, material) is clearly delineated using proper list (`<ul>`, `<ol>`) or table (`<table>`) structures with clear headers (`<th>`).

Segment detailed product descriptions into logical chunks of approximately 300-500 words, each focusing on a specific feature or benefit.

Avoid 'floating' context; ensure each description chunk explicitly reiterates the core product name or SKU it pertains to, especially in multi-variant listings.

Eliminate ambiguous pronouns (e.g., 'It works great for...') and replace them with the specific product name or feature being described (e.g., 'The [Product Name] offers superior durability...').
