Validation settings
Keep public validation focused on required fields, recommended fields, and preview readiness.
Checks required fields for detected schema types.
Highlights fields that may improve rich-result quality but are not always required.
Provides rule-based suggestions for missing, invalid, or weak fields.
Preview is simulated from available schema fields and may not confirm search-engine eligibility.
Shows sanitized structured data in the Raw Data tab.
Fetches the page, extracts structured data, and validates detected schema types.
Free public checks are limited to 3 uses/day. CAPTCHA may appear for protection.
Check structured data before it becomes an SEO issue
Use Wranker to confirm whether schema exists, which types were detected, which fields need attention and whether a simulated preview can be generated.
Use it during internal linking audits, content optimisation, technical SEO reviews, website migrations and content hub planning.
Detected schema types
Identify Product, Article, FAQPage, BreadcrumbList, Organization and other supported schema types found on the page or in pasted JSON-LD.
JSON-LD, Microdata and optional RDFa
Check how structured data is implemented, extract public schema blocks and review the detected format for QA and handoff.
Required fields and warnings
Review missing required fields, invalid values, syntax issues and recommended-field warnings that may affect readiness or preview quality.
Simulated rich preview plus fix guidance
Preview Product, Article, FAQ, Breadcrumb and other rich-result styles from detected fields and use rule-based suggestions to resolve issues faster.
Structured data should be validated before publishing
Incorrect schema can create confusing signals and reduce rich-result readiness. Wranker gives SEOs, developers and content teams a practical workflow for checking markup quality before and after implementation.
Validate live and draft markup
Check implemented schema from a public URL or paste JSON-LD before it is added to a template, CMS or landing page.
Speed up fixes and handoff
Use actionable errors, warnings and copyable fix snippets to reduce back-and-forth between SEO and development teams.
Public-safe validation payloads
Keep internal formulas, API keys, cookies, private headers, provider IDs and hidden scoring logic out of public output.
How the Schema Markup Validator / Rich Result Preview works
Choose a validation mode, provide a public URL or JSON-LD snippet, adjust settings and open the dashboard-style validation output after submission.
Choose input mode
Select URL mode for a live public page or JSON-LD Code mode for draft schema that has not been published yet.
Enter URL or paste JSON-LD
Provide a public page URL, raw JSON-LD object, JSON-LD array or a single JSON-LD script tag for validation.
Review validation settings
Control required-field checks, recommended warnings, fix suggestions, simulated preview, raw data and extraction options.
Validate and review
Run the tool to open the dashboard-style validation output with detected schema, errors, warnings, preview data and fix guidance.
Validate schema during every important SEO workflow
Use the validator before publishing, after implementation, during technical audits or whenever structured data needs a clear QA handoff.
Technical SEO audits
Check which pages have schema errors, partial extraction, missing fields or unsupported structured data during site reviews.
Ecommerce and product QA
Review Product schema for offer fields, price currency, image URLs, availability and preview-readiness signals before launch.
Content and publisher QA
Validate Article, FAQPage and Breadcrumb markup so content pages include useful fields that match visible page content.
Developer handoff
Share exact schema fields, severity labels and rule-based repair guidance with developers after template or CMS changes.

Schema validation questions, answered
Practical details about URL mode, JSON-LD validation, simulated previews, exports and what continues inside the Wranker dashboard.
A Schema Markup Validator checks structured data on a page or pasted JSON-LD code and reports detected schema types, errors, warnings and preview readiness.
Enter a public URL or paste JSON-LD code, then click Validate Schema. Wranker detects schema types, validates fields and shows errors, warnings, preview data and fix suggestions.
Yes. Use JSON-LD Code mode to paste one JSON-LD object, an array of objects or a script tag containing JSON-LD.
URL mode can support JSON-LD and Microdata by default, with RDFa treated as optional or partial depending on implementation. Pasted code mode validates JSON-LD by default.
No. The preview is simulated from detected schema fields and does not guarantee search-engine eligibility or display.
It means required fields, invalid values, malformed JSON-LD or validation rules need attention before the markup is ready.
It means the page was checked, but no supported structured data was found. You can use Schema Markup Generator to create JSON-LD for the page.
Yes. Where export is available, you can export CSV, PDF or JSON validation data.
No. Wranker provides workflow-focused validation, simulated preview and fix suggestions. Use official testing tools for final Google-specific eligibility validation.
Fix critical errors first, add recommended fields where relevant, confirm the preview, implement the corrected markup and validate the live page again.
Validate Schema Markup Before Publishing
Enter a public URL or paste JSON-LD code to detect schema types, check errors and warnings, preview rich-result style output and copy fix suggestions.
