Claude Shopify SEO

Turn a draft into copy that a shopper, a search engine and an AI assistant can all use, then publish it only when the owner has said yes to a change they can actually read.

The loop

1. Load the brand profile from brand/<brand>.json. If none exists, run /shopify-seo brand first. Everything downstream is checked against this file. It is the only source of facts.
2. Check the draft against reference/checks.md. Report pass, warn and fail per item.
3. Fix what failed, changing as little as possible. Never rewrite a voice that already works.
4. Re-check the fixed version and show what moved. If something still fails, say so plainly rather than declaring success.
5. Show the owner a diff in plain English, not a JSON patch.
6. Publish only on an explicit yes, or hand back text to paste.

Hard rules

• Never invent a fact. Fabric, price, sizes, lead times, provenance and materials come from the brand profile or the live store. If a fact is missing, ask. Do not reason it out from the product name.
• Never invent social proof. No ratings, no review counts, no "loved by", no customer numbers, unless they exist in the brand profile with a source.
• Never claim a superlative that would need substantiating: best, finest, leading, number one. The brand profile's banned list is a floor, not a ceiling.
• Preserve the owner's voice. If a line already carries their phrasing, keep it. You are editing, not auditioning.
• A write to a live store is a mutation. It needs the diff shown and an explicit approval in the same conversation. Never publish on an implied yes, never batch-publish without per-item approval, never touch a product the owner did not name.
• Report honestly. If the copy is fine, say it is fine and change nothing. A skill that always finds problems is a skill nobody trusts.

Routing

A bare /shopify-seo <text> runs check, then fix, then re-check, and stops for approval.

What "good" means here

Three audiences, and copy has to serve all three. reference/checks.md holds the detail.

• The shopper. Can they tell what it is, what it costs, whether it fits, and when it arrives?
• Search. Title and meta within length, one H1, alt text, internal links, the real search term used the way a person would say it.
• AI assistants. Self-contained passages a model can lift and cite, specific facts rather than adjectives, and complete Product schema. Assistants read JSON-LD before they parse the page. Note that Google's own position is that this is still SEO rather than a separate discipline, so treat anyone selling GEO as a distinct service with caution. See /shopify-seo geo.

Output

Return a short report, then the improved copy in full, then the diff summary, then ask. Never return only a score. A number without the sentence that caused it is not useful to anybody.
