What SEO Schema Markup is

SEO Schema Markup is a free web toolkit for creating schema.org JSON-LD and checking it against Google requirements. Its generators cover FAQ, Product, Shopify Product, Article and Author, Local Business, Organization, Breadcrumb, Event, and Review and Rating markup. Fill out a form to create a snippet, then copy it into HTML, WordPress, Shopify, or a Google Tag Manager Custom HTML tag. Generator output includes live validation. For a separate check, paste JSON-LD or HTML into the validator to find missing required or recommended properties; detected issues link to the corresponding generator. The Shopify Product tool creates dynamic Liquid markup that fills product title, price, variants, and ratings. The tools run in the browser, and the site says markup is not uploaded. The project is open source under the MIT license and requires no signup. WebSensePro built the project, and the site identifies Bilal Naseer as its maker. Guides, blog posts, and a YouTube channel are also available.
