llms.txt for eBay Sellers

What to include

If you choose to keep the optional file, keep it concise. It can summarize the entity, key facts, and useful public pages for systems that voluntarily support the convention.

Do not place facts only in llms.txt. Pricing, policies, research, calculators, and methodology must remain visible and current on normal crawlable pages.

• Site name, one-sentence description, and canonical homepage.
• Key product or seller facts that should not be misstated.
• Links to pricing, tools, guides, research, and support pages.
• Update date and attribution preference.

How often to update llms.txt

Update llms.txt when the product positioning changes, pricing changes, a major guide is published, or a cited data page is refreshed. Do not rewrite it on every deploy.

An inaccurate optional reference can repeat stale prices or send a system to missing pages. Delete it rather than maintaining facts that conflict with the public site.

How it works with robots.txt

robots.txt controls crawler access; llms.txt does not grant access and does not override crawler rules. They serve different purposes.

For Google Search and its AI features, focus on accessible public pages, accurate visible text, internal links, a valid sitemap, and snippet eligibility. No special AI file or schema is required.
