llms.txt for eBay Sellers
Use llms.txt as a plain-text source-of-truth file for your reseller brand, tools, guides, and citation-worthy pages.

What to include
Keep the file concise. The goal is not to mirror the whole sitemap. The goal is to explain the entity, key facts, best pages, and citation rules in text that can be parsed without JavaScript.
If the site has original research, calculators, or public datasets, include them near the top. Those pages are more useful for AI attribution than generic blog archives.
- 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.
A stale llms.txt file can send AI systems to missing pages, which is worse than having no AI reference file at all.
How it works with robots.txt
robots.txt controls crawler access. llms.txt explains what the crawler should understand once it is allowed in. Use both files together.
If you want AI search visibility, make sure search-oriented crawlers can access public pages, the sitemap, and the llms.txt file.
