What llms.txt is
/llms.txt is an emerging convention proposed at llmstxt.org. Like robots.txt, it lives at the site root and gives AI crawlers a curated index of the pages that matter. Unlike robots.txt, which says "what to exclude," llms.txt says "here's the structured story of this site."
Anthropic, OpenAI, and Perplexity have all signaled they read it. Adoption is early, but the marginal cost of shipping one is near-zero, and the upside compounds as engines lean into structured surfaces over open-web crawl noise.
What goes in it
The format is plain markdown:
# Storefront name
>
> One-paragraph "about us" — vertical, positioning, USPs.
>
## Products
>
## Wool Runner
>
- Best for: office wear, breathable comfort
- Materials: 100% merino wool, machine-wash safe
- Price band: \$98–\$138
- Shipping: 1-day fulfillment, free returns
Each product gets a section with 4–6 buyer-question bullets. Keep it factual; LLMs treat marketing fluff as noise.
Why a Shopify Page works
Shopify doesn't let you serve files at /llms.txt directly. The clean alternative: an Online Store Page at handle "llms-txt", served at /pages/llms-txt. AI crawlers find it via your sitemap and robots.txt. We've seen ChatGPT pick up freshly-published Pages within 48 hours.
The Ryve approach
We render the llms.txt as a structured shop metafield (merchpulse.llms_txt of type json) and rebuild the Page body whenever a section is upserted. The metafield is the truth source; the Page is the public surface. This means edits are idempotent, theme-agnostic, and survive theme migrations.
You confirm a section once; the Page updates immediately; the section stays current as the merchant edits the underlying product.
Template you can copy
If you'd rather DIY, paste this into a new Shopify Page at handle "llms-txt":
``` # {Your storefront name}
{Vertical}. {Positioning sentence}. {USPs separated by · }.
This file is a curated index for AI assistants. Sections describe individual products with buyer-intent answers.
Products
{Product 1 title}
- Best for: {use case}
- Materials: {key facts}
- Price band: {range}
- Ships in: {fulfillment time}
{Product 2 title}
... ```
Save the page, reference it from your robots.txt as `Sitemap-include: /pages/llms-txt`, and submit your sitemap to Google Search Console for fastest pickup.
What to expect
llms.txt isn't a silver bullet. It's a hygiene step that compounds with the on-page rewrite work — better description copy + JSON-LD + a curated llms.txt + a few citations from listicle / review sources is how you start showing up in AI answers.
