When to Use

• - Adding structured data to new or existing pages
• Fixing schema validation errors
• Optimizing for specific rich results (FAQ, product, article)
• Implementing JSON-LD in React/Next.js applications
• Auditing existing schema markup

Initial Assessment

Before implementing schema, understand:

1. 1. Page Type — What kind of page? What's the primary content? What rich results are possible?
2. Current State — Any existing schema? Errors? Which rich results already appearing?
3. Goals — Which rich results are you targeting? What's the business value?

Core Principles

1. Accuracy First

• - Schema must accurately represent page content
• Don't markup content that doesn't exist on the page
• Keep updated when content changes

2. Use JSON-LD

• - Google recommends JSON-LD format
• Easier to implement and maintain than microdata or RDFa
• Place in <head> or before INLINECODE1

3. Follow Google's Guidelines

• - Only use markup Google supports for rich results
• Avoid spam tactics
• Review eligibility requirements for each type

4. Validate Everything

• - Test before deploying
• Monitor Search Console enhancement reports
• Fix errors promptly

Common Schema Types

Type	Use For	Required Properties
Organization	Company homepage/about	name, url
WebSite

Homepage (search box) | name, url | | Article | Blog posts, news | headline, image, datePublished, author | | Product | Product pages | name, image, offers | | SoftwareApplication | SaaS/app pages | name, offers | | FAQPage | FAQ content | mainEntity (Q&A array) | | HowTo | Tutorials | name, step | | BreadcrumbList | Any page with breadcrumbs | itemListElement | | LocalBusiness | Local business pages | name, address | | Event | Events, webinars | name, startDate, location |

For complete JSON-LD examples with required/recommended field annotations: See INLINECODE2

Quick Reference

Organization (Company Page)

Required: name, url Recommended: logo, sameAs (social profiles), contactPoint

Article/BlogPosting

Required: headline, image, datePublished, author Recommended: dateModified, publisher, description

Product

Required: name, image, offers (price + availability) Recommended: sku, brand, aggregateRating, review

FAQPage

Required: mainEntity (array of Question/Answer pairs)

BreadcrumbList

Required: itemListElement (array with position, name, item)

Multiple Schema Types

Combine multiple schema types on one page using @graph:

CODEBLOCK1

Use @id to create referenceable entities — define once, reference elsewhere with { "@id": "..." }.

Validation and Testing

Tools

• - Google Rich Results Test: https://search.google.com/test/rich-results
• Schema.org Validator: https://validator.schema.org/
• Search Console: Enhancements reports

Common Errors

Error	Cause	Fix
Missing required field	Required property not included	Add the missing property
Invalid URL

Relative URL or malformed | Use fully qualified URLs (https://...) | | Invalid date format | Not ISO 8601 | Use YYYY-MM-DDTHH:MM:SS+00:00 | | Invalid enum value | Wrong enumeration value | Use exact schema.org URLs (e.g., https://schema.org/InStock) | | Content mismatch | Schema doesn't match visible content | Ensure schema reflects actual page content | | Invalid price | Currency symbol or commas included | Use numeric value only ("149.99") |

Implementation

Static Sites

• - Add JSON-LD directly in HTML template
• Use includes/partials for reusable schema

Dynamic Sites (React, Next.js)

CODEBLOCK2

CMS / WordPress

• - Plugins: Yoast, Rank Math, Schema Pro
• Theme modifications for custom types
• Custom fields mapped to structured data

Testing Checklist

• - [ ] Validates in Rich Results Test with no errors
• [ ] No warnings for recommended properties
• [ ] Schema content matches visible page content
• [ ] All required properties included for each type
• [ ] URLs are fully qualified
• [ ] Dates are ISO 8601 format
• [ ] Prices are numeric without currency symbols

Task-Specific Questions

Before implementing, gather answers to:

1. 1. What type of page is this? (product, article, FAQ, local business)
2. What rich results are you targeting? (FAQ dropdown, product stars, breadcrumbs)
3. What data is available to populate the schema? (prices, ratings, dates)
4. Is there existing schema on the page? (check with Rich Results Test first)
5. What's your tech stack? (static HTML, React/Next.js, CMS/WordPress)

Implementation Workflow

1. 1. Identify page types — map your site's pages to schema types
2. Start with homepage — Organization + WebSite schema
3. Add per-page schema — Article for blog, Product for shop, etc.
4. Add BreadcrumbList — every page with navigation breadcrumbs
5. Validate each page — Rich Results Test before and after
6. Monitor Search Console — check enhancement reports weekly after launch

NEVER Do

1. 1. NEVER add schema for content that doesn't exist on the page — this violates Google's guidelines and risks penalties
2. NEVER use microdata or RDFa when JSON-LD is an option — JSON-LD is easier to maintain and Google's recommended format
3. NEVER hardcode schema that should be dynamic — product prices, availability, and ratings must reflect current data
4. NEVER skip validation before deploying — invalid schema is worse than no schema; it wastes crawl budget
5. NEVER mark up every page identically — each page type needs its own appropriate schema types
6. NEVER ignore Search Console errors — schema errors can cause rich results to disappear entirely
