How to add llms.txt to a Shopify store
Shopify themes do not ship an llms.txt file. You add one. The file should live at https://yourstore.com/llms.txt so crawlers that look for the convention can find it.
Option 1: an app
A Shopify app can generate the file from products and keep it current. That is the job of ADYKO AEO: monthly generation on the free plan, daily on Pro at $3.99. Avada AEO is the larger, more reviewed alternative.
Option 2: host it yourself
If you already run a custom domain or a marketing site, you can serve a static llms.txt there and point AI readers at the store URLs. This is what ADYKO does on adyko.com. It is not a replacement for a store that changes inventory every day.
What to put in the file
- Store name and one-sentence description
- Who the store is for, and who it is not for
- Top collections and flagship products with live URLs
- Pricing or shipping facts you do not want hallucinated
- A date. Stale files get ignored or misquoted
What to skip
Do not keyword-stuff. Do not invent review counts. Do not promise that ChatGPT will rank the catalog. The file should be the shortest honest brief a model can quote.
