Structured Data Markup (Schema) Complete Checklist

What is Structured Data, Schema & Rich Snippets?

Definitions:

●       Structured Data: A standardized format for providing information about a page.

●       Schema Markup: A vocabulary (from Schema.org) used to label content in structured data.

●       Rich Snippets: Enhanced search results (e.g., with reviews, images) powered by structured data.

Why Use Structured Data?

●       Improves search appearance (rich results)

●       Enhances click-through rates (CTR)

●       Helps search engines understand page meaning

●       Supports AI-driven experiences (Knowledge Graph, SGE, voice search)

Implementation Checklist

1. Choose Where to Add Schema

●       Sitewide (e.g., Breadcrumb, WebPage schema)

○       Add via CMS settings (e.g., header/footer script fields)

●       Page-specific (e.g., Product, Event schema)

○       Add via page-level script fields or template fields

2. Select the Right Schema Type

Use Google’s Search Gallery to:

●       Find schema types based on content (Article, Product, FAQ, LocalBusiness, etc.)

●       Learn required + recommended properties

3. Generate the JSON-LD Markup

3 Options:

1. Use Plugins (WordPress only):
   

○       Yoast SEO – Auto applies basic schemas (WebPage, Article)

○       RankMath – Gives control over schema per post/page

○       Easy but limited in depth and customization

2. Use Schema Generators:
   

○       Merkle’s JSON-LD Generator – Easy UI for beginners

○       Schemantra – Advanced, supports complex relationships with @id

○       RankRanger Schema Generator – Supports subtype attributes

3. Manual JSON-LD Creation:
   

○       Offers full control and nesting

○       Required for connecting entities (contextual SEO)

○       Ideal for advanced SEO or complex sites

4. Use ChatGPT (with precise prompts):
   

○       Start with a base schema prompt (e.g., “Generate Person schema with name, jobTitle, worksFor”)

○       Include sameAs, alternateName, and @id for relationships

4. Test & Validate Schema

Use:

●       Rich Results Test – Google’s official testing tool

●       Schema.org Validator

●       Classy Schema Visualizer – See entity relationships

What to Check:

●       Errors

●       Warnings

●       Missing required/recommended properties

●       Nesting and entity linking

Advanced: Create a Knowledge Graph

Connected Schema Markup:

●       Use @id fields to link entities:

○       e.g., connect Organization, WebPage, and Product

●       Use Schema Paths Tool by SchemaApp to discover entity connection logic

Example:

"@context": "https://schema.org",

"@type": "Product",

"name": "Canon EOS 90D",

"brand": {

  "@type": "Organization",

  "@id": "#canon",

  "name": "Canon"

}

Quality Guidelines

Google requires:

●       Schema reflects actual visible content

●       All required and recommended properties

●       No misleading or spammy markup

●       Canonical pages and duplicates must also have matching schema

Check:

●       Are images crawlable?

●       Is content relevant and accurate?

●       Are all reviews/user-generated content real?

In Details

PART 1: What Is Structured Data?

Structured data is a standardized way to label your website’s content so search engines understand it better.

Think of it like this:

●       Your content = a book

●       Structured data = a table of contents + glossary

It helps Google know that:

●       A number is a price

●       A string is a product name

●       A sentence is a review, not just text

Google uses structured data to create Rich Snippets and Knowledge Graph Panels.

PART 2: Why Structured Data Is Important

Benefit	Explanation
Enhanced Search Listings	Rich results like images, stars, reviews, FAQs
Higher CTR	Eye-catching previews in SERPs improve clicks
Semantic Understanding	Helps Google’s AI understand your content type
Better Analytics	Track schema visibility in Google Search Console
Voice Search Optimization	Required for Alexa, Google Assistant, SGE

PART 3: Types of Schema (Most Important)

These are the most-used and SEO-impactful types:

Article / BlogPosting

●       For blogs, news posts

●       Add author, datePublished, headline, image

Product

●       For ecommerce

●       Includes price, availability, brand, SKU, rating

Event

●       Used for concerts, webinars, launches

●       Add location, date, organizer, tickets

FAQPage

●       Adds expandable questions in Google results

●       Format: question + acceptedAnswer

LocalBusiness

●       For brick-and-mortar stores or service providers

●       Includes opening hours, geolocation, logo, sameAs links

Organization

●       For company-wide schema (e.g. in footer or header)

●       Add logo, founder, contactPoint, sameAs

PART 4: How to Implement Structured Data

You have 3 options:

Option 1: WordPress Plugins

Easy but limited

●       Yoast SEO: Basic schemas like WebPage, Article

●       RankMath: More flexible, supports FAQ, Product, etc.

Option 2: Online Schema Generators

●       Merkle Schema Generator

●       Schema Markup Validator

●       ClassySchema Visualizer

These generate JSON-LD scripts you can paste into your HTML.

Option 3: Manual Code (Advanced)

<script type="application/ld+json">

{

  "@context": "https://schema.org",

  "@type": "Product",

  "name": "Logitech MX Master 3",

  "brand": "Logitech",

  "price": "99.99",

  "priceCurrency": "USD",

  "availability": "https://schema.org/InStock"

}

</script>

PART 5: Schema Placement

Where to Place the Schema Code:

●       In the <head> section of your page OR

●       Just before the </body> tag

Use <script type="application/ld+json"> to wrap the data.

For CMS Users:

●       WordPress: Use theme header/footer, or plugin fields

●       Shopify: Use theme.liquid or product-template.liquid

●       Webflow/Squarespace: Use Embed blocks

PART 6: Required vs Optional Properties

Property	Required?	Notes
@context	Yes	Always "https://schema.org"
@type	Yes	E.g. Product, BlogPosting
name	Yes	Title of item (product/post)
description	Yes	Short meta-like summary
image	Yes	Must be crawlable
url	Yes	Canonical or content link
offers (for Product)	Yes	Contains price, currency, stock
sameAs	Optional	For linking to social profiles

PART 7: Linking Entities (Advanced but Powerful)

Use @id and sameAs to connect things.

Example:

"@type": "Person",

"@id": "https://example.com/#author",

"name": "Hasib Al Hasan",

"sameAs": [

  "https://www.linkedin.com/in/hasibseo",

  "https://twitter.com/hasibseo"

]

This connects your author profile to your LinkedIn and Twitter – builds entity trust.

PART 8: Testing Your Schema (Critical)

Always test your structured data before and after implementation.

Tools:

1. Rich Results Test
   

○       Checks if you're eligible for stars, FAQs, reviews, etc.

2. Schema.org Validator
   

○       Pure syntax validation

3. Classy Schema Visualizer
   

○       See graph-style entity mapping

PART 9: Tracking Schema in Google Search Console

Navigate to:

GSC → Enhancements

You'll see:

●       Which schema types are detected

●       Errors (missing fields, invalid data)

●       Which URLs are eligible for rich results

Fix warnings too – they’re not fatal but they limit full display.

PART 10: Schema for AI-Driven Search (SGE, ChatGPT, Perplexity)

Structured data plays a role in:

●       Google SGE (AI Overviews)

●       ChatGPT citations

●       Perplexity.ai rankings

Add:

●       Clear author and datePublished for EEAT

●       sameAs links for brand presence

●       Internal entity connections via @id

This helps AI understand your domain and surface your answers.

4. Embed snippet into webpage in the head or body tag
   
   
5. Test using Google’s Rich Results Test before publishing

6. Common Mistakes & How to Avoid Them

Mistake	Fix
Wrong schema type (e.g. using Review for blog post)	Match page content with correct schema
Incomplete or missing required properties	Use official Schema.org definitions
Hidden or non-visible elements marked up	Only mark up content visible to users (per guidelines)
Errors or warnings not addressed	Validate before and after deployment

7. Enhancing Schema for Rich Snippets & CTR

●       Aggregated Ratings: Use AggregateRating schema to enable star ratings

●       About Events: Event schema with startDate, location, offers

●       BreadcrumbList: Helps Google display site hierarchy

●       Monitor performance using Search Console reports on rich result impressions and errors

9. Advanced Tips & Pro Strategies

●       Use multiple schema types on one page (e.g., Article + Breadcrumb + FAQ) — choose a primary schema properly

●       Update schema regularly, as schema.org adds new types or deprecates old ones

●       Use plugins like Rank Math, Schema Pro for easier setup and editing

●       Maintain transparency: schema must reflect actual page content and visible information
