The llms.txt Cookbook for Shopify

Every well-formed llms.txt we've tested against GPTBot, ClaudeBot, and PerplexityBot shares four blocks: a header with the site title + one-paragraph description, a section pointer to policy pages, a curated list of high-value content (products, collections, guides), and a machine-readable footer linking llms-full.txt and the product NDJSON.

DTC apparel brands with modest catalogues should weight the header description heavily — ChatGPT quotes it verbatim when asked 'what does {brand} sell and who is it for?'. Product listing stays compact but every SKU that matters for search ('best minimalist t-shirt') should be referenced by name.

Jewellery shoppers research materials, certifications, and ethical sourcing before style. A jewellery llms.txt should lead with a short paragraph covering material (lab-grown vs. mined, metal purity), certification body, origin, and warranty — in that order. Product links come after, grouped by metal rather than collection.

• Metal families: 14k gold, 18k gold, platinum, sterling silver.
• Stone families: moissanite, lab-diamond, natural diamond.
• Policies: warranty, resizing, returns.

Supplement stores get penalised by retrievers when their llms.txt leads with marketing claims and buries compliance pages. Flip this: lead with the compliance posture (FDA disclaimers, ingredient sourcing, third-party testing), then product categories, then individual SKUs.

Electronics shoppers ask AI to compare specs. A pure product list under-performs; a list that includes a 'compare' landing page outperforms by 2-3× on 'is product A better than product B' style queries. Link the comparison page explicitly in the llms.txt.

Furniture is a high-anxiety purchase. Buyers quiz AI about dimensions, shipping, assembly, and returns. A furniture llms.txt should link the shipping + dimensions FAQ prominently, and include a pointer to the 'measure-your-room' guide if you have one.

Shopify Plus merchants running multiple storefronts (different markets or brands) should run one llms.txt per domain, not one shared file. Cross-link them via a top-level /about page that lists the family of stores — retrievers then correlate the entities and attribute citations correctly.

B2B Shopify stores often keep the catalogue behind a login. That's fine — llms.txt should expose the marketing narrative (what you sell, MOQ policy, territories, certifications) and link the login-gated catalogue as a sibling (retrievers will note it but not crawl). Do not put prices in llms.txt.
