Schema Markup Generator
Build or check JSON-LD for 14 practical schema types with guided fields, live validation, examples, and official testing links.
How to use
- Choose Generate and select the schema type, or choose Check existing to inspect JSON-LD you already have.
- Complete the required fields and add relevant recommended details that are visible on the page.
- Resolve local errors and warnings while reviewing the live JSON-LD or script output.
- Copy or download the result, then confirm eligibility with the linked official validators before publishing.
Example
Input
A Product with name, image, offer price, currency, availability, and brand
Output
Nested Product JSON-LD with an Offer and local validation status.
What Schema Markup Generator returns
Schema Markup Generator is designed to build or inspect JSON-LD for common content, business, commerce, and search page types.
Input: one of 14 schema types with guided fields, or existing raw or script-wrapped JSON-LD. Output: formatted raw JSON-LD or a safe application/ld+json script with local preflight results.
How Schema Markup Generator works
The builder maps visible page facts into nested schema properties, while the checker parses existing JSON-LD and flags common required, format, and support issues.
Clear local errors, verify every claim against visible page content, then use the official Schema Markup Validator and Google's Rich Results Test where supported.
A useful situation for Schema Markup Generator
Use it when you are preparing a product, article, local business, event, job, recipe, video, profile, or site page before deployment.
The workflow is intended for SEO specialists, developers, marketers, ecommerce teams, and technical founders.
Limits and common errors
Local preflight does not guarantee a rich result; FAQ visibility is restricted, HowTo rich results are deprecated, and WebSite markup now targets site-name signals.
A common mistake is publishing schema that claims content or offers not visible on the page.
Privacy and the next step
Generation, pasted-source parsing, validation, and file import run locally without fetching a page or uploading its data.
For a broader workflow, combine page-specific schema with Open Graph tags for sharing and robots.txt for crawler access policy.
If the result matters later, keep schema updates aligned with page copy, prices, availability, and FAQ changes.
FAQ
Does passing the local check guarantee a Google rich result?
No. The local check catches common structure and field issues, while Google decides eligibility and display. Confirm the final markup with Google's Rich Results Test where applicable.
Can I check an existing JSON-LD script?
Yes. Paste raw JSON-LD or a complete application/ld+json script element, or import a local JSON, JSON-LD, TXT, or HTML file.
Why are FAQPage and WebSite shown with limitations?
Google limits FAQ rich results to selected authoritative sites, and WebSite markup now supports site-name signals rather than the retired sitelinks search box. Schema.org validity and Google search features are not the same thing.
Is Schema Markup Generator free to use?
Yes. The public Schema Markup Generator runs in the browser and does not require a sign-in for normal use.
How does Schema Markup Generator handle my input?
Generation, pasted-source parsing, validation, and file import run locally without fetching a page or uploading its data.
What should I check before relying on the result?
Clear local errors, verify every claim against visible page content, then use the official Schema Markup Validator and Google's Rich Results Test where supported. Also confirm that the input reflects the exact situation you are working on.
What is a common mistake with Schema Markup Generator?
A common mistake is publishing schema that claims content or offers not visible on the page. Review the original material and the final output before publishing or sharing it.
What should I use with Schema Markup Generator?
Combine page-specific schema with Open Graph tags for sharing and robots.txt for crawler access policy. Related tools can help you check the same task from another angle.
