What do I need to use Schema Markup?

The page & its content; The rich result you want; The data.

Is Schema Markup free to use?

Yes — run it free in the browser playground (no API key needed for the sponsored trial, or bring any provider key), or install it into Claude Code, Cursor, ChatGPT and more via npx pm-claude-skills. MIT-licensed and open source.

Schema Markup

Q: How do I know the Schema Markup output is good?

The skill verifies itself against its own quality checks: The schema type matches the page content and the intended rich result; The JSON-LD is valid (proper @context/@type, correct nesting) and uses real values; All Google-required fields for that rich result are present; Markup reflects content actually visible on the page — no hidden or fabricated data.

Generate structured-data (Schema.org / JSON-LD) markup to win rich results in search. Use when asked about schema markup, structured data, rich snippets, JSON-LD, or making a page eligible for stars/FAQ/breadcrumb results. Produces valid JSON-LD for the right schema type, the rich-result it targets, required vs. recommended fields, and validation/guideline notes.

What to give it

▸The page & its content — what the page is (product, article, FAQ, local business, event, recipe, how-to…).

▸The rich result you want — e.g. review stars, FAQ accordion, breadcrumbs, sitelinks, event listing.

▸The data — the actual values (name, price, rating, dates, Q&As) — markup must match visible content.

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The schema type matches the page content and the intended rich result

✓The JSON-LD is valid (proper @context/@type, correct nesting) and uses real values

✓All Google-required fields for that rich result are present

✓Markup reflects content actually visible on the page — no hidden or fabricated data

✓Validation steps and the relevant structured-data guidelines are noted

⚠️ What it refuses to do

Do not mark up content that isn't visible on the page — Google treats that as spam

Do not fabricate ratings/reviews or self-apply AggregateRating without real reviews

Do not omit required fields — the rich result simply won't trigger

Do not use the wrong type (e.g. Product for an article) — it won't validate

Do not ship without validating in the Rich Results Test
