Schema markup generator — free JSON-LD for Product & FAQ

Quick answer: pick a schema type, fill the fields, and copy valid JSON-LD you can paste straight into your theme. Product, FAQPage, BreadcrumbList, LocalBusiness and Article are covered. Everything runs in your browser — nothing is sent to a server.

What this generates

Valid JSON-LD, the format Google recommends over Microdata and RDFa. Each type below maps to a rich result Google actually supports.

The rule that decides whether markup helps or hurts

Mark up what a visitor can see. That single rule covers almost every structured-data manual action: FAQ markup for questions that are not on the page, review stars for reviews that live on another site, a schema price that disagrees with the visible price. Google's guidelines call this out explicitly, and it is the one failure mode that turns a missed rich result into a penalty.

Invalid markup, by contrast, is simply ignored. That asymmetry is worth internalising — being wrong about syntax costs you an opportunity, being dishonest about content costs you standing.

Shopify specifics

Shopify themes ship some structured data already, and it is usually partial. Dawn emits a Product block with name, image and offers but no sku, no brand and no aggregateRating. Adding a second, fuller Product block on the same page is not a conflict — Google merges same-@type blocks — but two blocks that state different prices is exactly the contradiction described above.

Check what your theme already emits before you paste:

1. Open a product page and view source.
2. Search for application/ld+json.
3. Read the @type values you find.

Then add only what is missing. Shopify schema markup walks through the theme files involved, and adding schema to Shopify without an app covers doing it by hand.

@graph, and when to use it

Once a page carries three or four types, a single @graph array is easier to maintain than four separate script tags, and it lets the types reference each other:

{
  "@context": "https://schema.org",
  "@graph": [
    { "@type": "Organization", "@id": "https://example.com/#org", "name": "Ember & Oak" },
    { "@type": "Product", "brand": { "@id": "https://example.com/#org" } }
  ]
}

The @id reference means the brand is declared once and pointed at, rather than repeated with slightly different values on every product — which is how price and brand drift apart over a few hundred products.

Validate before and after

The Rich Results Test answers "which rich result does this qualify for", the Schema Markup Validator answers "is this valid schema.org", and Search Console's Enhancements reports answer "what did Google actually parse on my live pages". You need all three: the first two test a snippet, only the third tests your site.

RankEngine writes Product, FAQ, Breadcrumb, Organization and LocalBusiness blocks into a Shopify store automatically and then re-reads the live page to confirm they landed — see Shopify schema markup for how that verification step works.
