When someone asks ChatGPT or Perplexity for a product, the answer is built from pages the AI could read. llms.txt is a small text file that gives those engines a clean map of your store.
What is llms.txt?
It’s a plain Markdown file served from your domain. It lists who you are, what you sell, and links to your most useful pages — without the menus, pop-ups and scripts that make a normal page hard for a model to read.
Why it matters for Shopify stores
Shopify themes are built for shoppers, not language models. A short, structured summary makes it easier for AI engines to understand your catalogue and point to the right product page.
What goes inside
Keep it short and factual. A good store file usually has:
# Aayogi Ayurveda > Ayurvedic hair and skin care, made in India. ## Collections - [Hair care](/collections/hair) - [Skin care](/collections/skin) ## Policies - [Shipping](/policies/shipping-policy) - [Returns](/policies/refund-policy)
How to serve it on Shopify
Shopify doesn’t let you drop a file at the root of your domain. The usual route is an app proxy, which serves the file from a path on your store. QueRank generates the file from your catalogue and serves it at /apps/querank/llms.txt.
Don’t forget the crawlers
A file only helps if AI crawlers are allowed to visit. Check your robots settings for bots like GPTBot, ClaudeBot and PerplexityBot, and decide which ones you want to let in.
