🗺️ Schema.org Mastery
Your machine-readable DNA - make AI systems understand you perfectly
What Is Schema.org?
Section titled “What Is Schema.org?”Schema.org is a vocabulary for structured data on the web.
Translation: It’s how you tell machines (search engines, AI agents, crawlers) EXACTLY what your content means.
Without Schema:
<p>Basecamp costs $299</p>Machine reads: “Some text about numbers”
With Schema:
{ "@type": "SoftwareApplication", "offers": { "@type": "Offer", "price": "299", "priceCurrency": "USD" }}Machine reads: “This is software. It costs $299 USD.”
The difference: Ambiguous text vs. structured, queryable data.
Why Schema Matters for AI
Section titled “Why Schema Matters for AI”AI systems need structure:
Without Schema, AI must:
- Parse unstructured HTML
- Guess at meaning
- Infer relationships
- Hope for accuracy
With Schema, AI can:
- Read structured data directly
- Understand precisely
- Extract facts confidently
- Cite accurately
Result: Schemaed content is 10-100x more likely to be understood and cited by AI.
The Three Implementation Methods
Section titled “The Three Implementation Methods”1. JSON-LD (Recommended)
Section titled “1. JSON-LD (Recommended)”JavaScript Object Notation for Linked Data
<script type="application/ld+json">{ "@context": "https://schema.org", "@type": "Organization", "name": "Basecamp"}</script>Pros:
- ✅ Clean, separate from HTML
- ✅ Easy to generate programmatically
- ✅ Doesn’t affect page rendering
- ✅ Recommended by Google
- ✅ Best for AI parsing
Cons:
- ❌ Requires JavaScript support (minimal concern)
Use this 95% of the time.
2. Microdata
Section titled “2. Microdata”Inline HTML attributes
<div itemscope itemtype="https://schema.org/Organization"> <span itemprop="name">Basecamp</span></div>Pros:
- ✅ Tightly coupled to visible content
- ✅ No duplication
Cons:
- ❌ Clutters HTML
- ❌ Harder to maintain
- ❌ Less flexible
Use when: You need HTML validation or can’t use JSON-LD.
3. RDFa
Section titled “3. RDFa”Resource Description Framework in Attributes
<div vocab="https://schema.org/" typeof="Organization"> <span property="name">Basecamp</span></div>Pros:
- ✅ W3C standard
- ✅ Powerful for complex data
Cons:
- ❌ More complex
- ❌ Less common
- ❌ Overkill for most use cases
Use when: You have complex linked data requirements (rare).

The Philosophy
Section titled “The Philosophy”Schema isn’t SEO. It’s communication.
You’re telling machines:
- Who you are
- What you do
- Where you are
- How much you cost
- Who trusts you
Clear communication = AI can understand, trust, and cite you.
“If your data isn’t structured, AI can’t understand it. If AI can’t understand it, you’re invisible.” 🗺️
