Schema Markup Generator

This skill creates Schema.org structured data markup in JSON-LD format to help search engines understand your content and enable rich results in SERPs.

When to Use This Skill

  • Adding FAQ schema for expanded SERP presence
  • Creating How-To schema for step-by-step content
  • Adding Product schema for e-commerce pages
  • Implementing Article schema for blog posts
  • Adding Local Business schema for location pages
  • Creating Review/Rating schema
  • Implementing Organization schema for brand presence
  • Any page where rich results would improve visibility

What This Skill Does

  1. Schema Type Selection: Recommends appropriate schema types
  2. JSON-LD Generation: Creates valid structured data markup
  3. Property Mapping: Maps your content to schema properties
  4. Validation Guidance: Ensures schema meets requirements
  5. Nested Schema: Handles complex, multi-type schemas
  6. Rich Result Eligibility: Identifies which rich results you can target

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:

  1. Page URL or full HTML content
  2. Page type (article, product, FAQ, how-to, local business, etc.)
  3. Specific data needed for schema (prices, dates, author info, Q&A pairs, etc.)
  4. 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:

  1. 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**:
1. [Primary schema type] - [reason]
2. [Secondary schema type] - [reason]

  2. Generate FAQ Schema

    ### FAQ Schema (FAQPage)

**Requirements**:
- Minimum 2 Q&A pairs
- Questions must be complete questions
- Answers should be comprehensive
- Must match visible page content

**Generated Schema**:

```json
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "[Question 1 - exactly as shown on page]",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "[Complete answer text]"
      }
    },
    {
      "@type": "Question",
      "name": "[Question 2]",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "[Complete answer text]"
      }
    }
  ]
}

    Rich Result Preview:

    [Page Title]
[URL]
[Meta Description]

      <script type="application/ld+json">
    [Your JSON-LD schema here]
  </script>
</body>

    Validation Steps

    1. ~~schema validator

      • Test your live URL or paste code
      • Check for errors and warnings

    2. Schema.org Validator

    3. ~~search console

        "@type": "Answer",
        "text": "SEO (Search Engine Optimization) is the practice of optimizing websites and content to rank higher in search engine results pages (SERPs).

        "@type": "Answer",
        "text": "SEO typically takes 3-6 months to show significant results, though this varies based on competition, domain authority, and effort invested.

      "name": "Is SEO better than paid advertising?",
      "acceptedAnswer": {

        "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."
      }
    }

## Tips for Success

1. **Match visible content** - Schema must reflect what users see
2. **Don't spam** - Only add schema for relevant content
3. **Keep updated** - Update dates and prices when they change
4. **Test thoroughly** - Validate before deploying
5. **Monitor Search Console** - Watch for errors and warnings
