SEO Schema Markup
What it is
SEO Schema Markup is a free web toolkit for generating schema.org JSON-LD and validating markup against Google requirements. Generators cover FAQ, Product, Shopify Product, Article and Author, Local Business, Organization, Breadcrumb, Event, and Review and Rating schema. Complete a form to create markup, then copy the snippet to add to HTML, WordPress, Shopify, or a Google Tag Manager Custom HTML tag. Generators offer live validation, and the validator accepts pasted JSON-LD or HTML to flag missing required and recommended properties. It also links detected issues to the corresponding generator; the site recommends Google's Rich Results Test for a final eligibility check. The Shopify Product generator creates dynamic Liquid markup that fills in 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 it, and Bilal Naseer is named as its maker. The site also links to a YouTube channel and provides guides and blog posts.
