SEO REVIEW LAB / SCHEMA MARKUP GENERATOR

Schema Markup Generator

Create a focused JSON-LD draft for a WebPage, Article, or Organization from reviewed entity details, without wrapping or publishing the script.

Runs in this browser tabNo account requiredName up to 200 characters; page and optional image URLs up to 500; description up to 500; publisher up to 160. Three schema types.

Step 1 / Build the brief

Describe one real entity

6 fields

Choose the type that matches the page or organization and enter only facts visible on, or authoritative for, the destination.

Before generationThe output is a JSON object without a script wrapper so it can be reviewed, validated, and integrated deliberately.

Checking database publication status before enabling this workspace.

No crawl or upload

The entered brief is processed in this browser tab. These tools do not crawl the supplied URL, fetch remote images, or send the draft to Nirmion.

Transparent transformation

The workspace uses visible rules, length counts, URL parsing, and standards-shaped templates rather than hidden ranking scores or unverified AI claims.

Human approval required

A technically valid draft can still be inaccurate for a page, campaign, platform, or policy. Test the result and obtain the appropriate approval before release.

Plain-language guide

How type-specific properties are mapped

Nirmion always writes the Schema.org context and selected type. WebPage uses name, URL, description, and an optional primaryImageOfPage object. Article maps the name to headline, uses mainEntityOfPage, and optionally adds image and publisher Organization. Organization maps the optional image as logo. URLs are validated, but no page, image, organization, or publisher claim is fetched or verified.

01
Start with verified inputs
Select the narrowest supported type that accurately represents the entity, then use public names, canonical URLs, plain descriptions, and approved image or publisher details.
02
Understand the transformation
The browser maps the supplied values into a deterministic type-specific JSON object and omits empty optional properties rather than inventing data.
03
Test the destination
Validate the JSON-LD with Schema.org and destination-specific tooling, place it in an application/ld+json script through your site code, and confirm it matches visible content.

Useful when

Practical jobs this tool supports

Prepare a basic Article draft for an editorial page.
Describe a public organization with its official URL and logo.
Create a minimal WebPage entity for developer review.

Release check

Structured data must match reality

Syntax is only the first check. Review type selection, property meaning, visible content, ownership, and destination-specific eligibility.

The selected type accurately describes the entity.
Names, descriptions, URLs, images, and publisher details are authoritative.
The markup represents content visible to users where required.
The integrated page passes current validators and policy review.

Important boundary

Valid JSON does not guarantee a rich result

Search engines support selected structured-data features and apply technical, content, quality, and policy rules. Google explicitly does not guarantee a rich result even when markup validates. This generic draft is not eligibility certification.

Questions before publishing

What a careful user should know

Use the draft to start a review, not to skip type-specific documentation and validation.

Why is there no script tag?

The downloadable object is easier to review and validate. Your site should insert it inside a correctly typed JSON-LD script.

Does Nirmion check the page content?

No. It does not crawl the page or verify that supplied properties are visible and accurate.

Can this guarantee a rich search feature?

No. Valid syntax, supported types, required properties, content quality, policies, crawling, and search-engine decisions all matter.
