What SEO Schema Markup is
SEO Schema Markup is a free web toolkit for creating schema.org JSON-LD and validating markup against Google requirements. Its generators cover FAQ, Product, Shopify Product, Article and Author, Local Business, Organization, Breadcrumb, Event, and Review and Rating schema. Users complete a form, then copy a generated script snippet for a site. Generators offer live validation and one-click copying. The validator accepts pasted JSON-LD or HTML, identifies missing required and recommended properties, and links detected issues to the relevant generator. The Shopify Product generator creates dynamic Liquid markup that fills in product title, price, variants, and ratings. The site describes adding snippets to HTML, WordPress, Shopify, or through a Google Tag Manager Custom HTML tag. The tools run in the browser, and the site says markup is never uploaded. The project is open source under the MIT license and requires no signup. The site also publishes schema guides and blog posts and links to a YouTube channel.
