How to Use

Generate Schema for Content

Generate schema markup for this [content type]: [content/URL]

Create FAQ schema for these questions and answers: [Q&A list]

Specific Schema Types

Create Product schema for [product name] with [details]

Generate LocalBusiness schema for [business name and details]

Audit Existing Schema

Review and improve this schema markup: [existing schema]

Data Sources

See CONNECTORS.md for tool category placeholders.

With ~~web crawler connected: Automatically crawl and extract page content (visible text, headings, lists, tables), existing schema markup, page metadata, and structured content elements that map to schema properties.

With manual data only: Ask the user to provide:

Page URL or full HTML content
Page type (article, product, FAQ, how-to, local business, etc.)
Specific data needed for schema (prices, dates, author info, Q&A pairs, etc.)
Current schema markup (if optimizing existing)

Proceed with the full workflow using provided data. Note in the output which data is from automated extraction vs. user-provided data.

Instructions

When a user requests schema markup:

Identify Content Type and Rich Result Opportunity

Reference the CORE-EEAT Benchmark item O05 (Schema Markup) for content-type to schema mapping:

CORE-EEAT Schema Mapping (O05)

Content Type	Required Schema	Conditional Schema
Blog (guides)	Article, Breadcrumb	FAQ, HowTo
Blog (tools)	Article, Breadcrumb	FAQ, Review
Blog (insights)	Article, Breadcrumb	FAQ
Alternative	Comparison*, Breadcrumb, FAQ	AggregateRating
Best-of	ItemList, Breadcrumb, FAQ	AggregateRating per tool
Use-case	WebPage, Breadcrumb, FAQ	—
FAQ	FAQPage, Breadcrumb	—
Landing	SoftwareApplication, Breadcrumb, FAQ	WebPage
Testimonial	Review, Breadcrumb	FAQ, Person

Use the mapping above to ensure schema type matches content type (CORE-EEAT O05: Pass criteria).

Schema Analysis

Content Type: [blog/product/FAQ/how-to/local business/etc.] Page URL: [URL]

Eligible Rich Results:

Rich Result Type	Eligibility	Impact
FAQ	✅/❌	High - Expands SERP presence
How-To	✅/❌	Medium - Shows steps in SERP
Product	✅/❌	High - Shows price, availability
Review	✅/❌	High - Shows star ratings
Article	✅/❌	Medium - Shows publish date, author
Breadcrumb	✅/❌	Medium - Shows navigation path
Video	✅/❌	High - Shows video thumbnail

Recommended Schema Types:

[Primary schema type] - [reason]
[Secondary schema type] - [reason]

Generate Schema Markup

Based on the identified content type, generate the appropriate JSON-LD schema. Supported types: FAQPage, HowTo, Article/BlogPosting/NewsArticle, Product, LocalBusiness, Organization, BreadcrumbList, Event, Recipe, and combined multi-type schemas.

Reference: See references/schema-templates.md for complete, copy-ready JSON-LD templates for all schema types with required and optional properties.

For each schema generated, include:

All required properties for the chosen type
Rich result preview showing expected SERP appearance
Notes on which properties are required vs. optional

When combining multiple schema types on one page, wrap them in a JSON array inside a single <script type="application/ld+json"> tag.

Provide Implementation and Validation

Implementation Guide

Adding Schema to Your Page

Option 1: In HTML <head>

&#x3C;head>
  &#x3C;script type="application/ld+json">
    [Your JSON-LD schema here]
  &#x3C;/script>
&#x3C;/head>

Option 2: Before closing 

  &#x3C;script type="application/ld+json">
    [Your JSON-LD schema here]
  &#x3C;/script>
&#x3C;/body>

Example

User: "Generate FAQ schema for a page about SEO with 3 questions"

Output:

## FAQ Schema for SEO Page

### Schema Markup

```json
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "What is SEO?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "SEO (Search Engine Optimization) is the practice of optimizing websites and content to rank higher in search engine results pages (SERPs). It involves technical optimizations, content creation, and link building to increase organic visibility and drive qualified traffic to your website."
      }
    },
    {
      "@type": "Question",
      "name": "How long does SEO take to work?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "SEO typically takes 3-6 months to show significant results, though this varies based on competition, domain authority, and effort invested. New websites may take 6-12 months, while established sites with existing authority can see improvements in 1-3 months for less competitive keywords."
      }
    },
    {
      "@type": "Question",
      "name": "Is SEO better than paid advertising?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "SEO and paid advertising serve different purposes. SEO provides sustainable, long-term traffic without per-click costs but takes time to build. Paid advertising delivers immediate results but stops when you stop paying. Most successful businesses use both: paid ads for immediate leads and SEO for long-term growth."
      }
    }
  ]
}

Implementation: Wrap the above JSON-LD in &#x3C;script type="application/ld+json">...&#x3C;/script>
 and place in &#x3C;head>
 or before &#x3C;/body>
. Test with ~~schema validator.
