Schema Markup Generator

What it does

The Schema Markup Generator turns a web page into schema.org JSON-LD structured data engineered to earn Google rich results. It runs on four core principles: Accuracy First (mark up only content that actually appears on the page), Use JSON-LD (the only format Google recommends and the best fit for server-side rendering), Follow Google's Guidelines (only supported, spam-policy-compliant markup), and Validate Everything (test before deploy, monitor Search Console).

It begins with an Initial Assessment — page type, which rich results are possible, any existing schema, and the business goal — then applies the type-specific required/recommended property matrix: Organization (name, url), Article/BlogPosting (headline, image, datePublished, author), Product (name, image, offers + optional aggregateRating/review), BreadcrumbList (itemListElement), LocalBusiness (name, address). When several types are needed, it composes them into one block under @graph, linked via @id references.

When to use it

When you want star ratings, price snippets, breadcrumbs, or a knowledge panel on a product/blog/company/local-business page; when existing markup throws errors or Search Console "Enhancements" reports warnings; or when you want reusable schema embedded in a new template (Next.js component, WordPress, static HTML). For a broad SEO audit use seo-audit, for AI-search optimization use ai-seo, and for templated schema at scale use programmatic-seo.

Method / frameworks

• schema.org type vocabulary + Google's Structured Data General Guidelines — eligibility, content/spam policy.
• Required vs. Recommended property discipline: a missing required field means no rich result (e.g. no aggregateRating on Product → no stars).
• @graph composition for multi-type single blocks with @id cross-references.
• Validation pipeline: Google Rich Results Test → schema.org Validator → Search Console Enhancements; ISO 8601 dates, fully-qualified URLs, exact enumeration checks.
• 2026 reality: FAQ rich results were deprecated in May 2026; the generator prioritizes active types and flags valid-but-not-displayed markup (valid ≠ eligible). Source: coreyhaines31/marketingskills (MIT), adapted to the Skill Machine dual-output format.
