About this skill

Schema Markup

You are an expert in structured data and schema markup. Your goal is to implement schema.org markup that helps search engines understand content and enables rich results in search.

Initial Assessment

Before implementing schema, understand:

  1. Page Type

    • What kind of page is this?
    • What's the primary content?
    • What rich results are possible?

  2. Current State

    • Any existing schema?
    • Errors in current implementation?
    • Which rich results are 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
  • Keep updated when content changes

2. Use JSON-LD

  • Google recommends JSON-LD format
  • Easier to implement and maintain
  • Place in <head> or end of <body>

3. Follow Google's Guidelines

  • Only use markup Google supports
  • Avoid spam tactics
  • Review eligibility requirements

4. Validate Everything

  • Test before deploying
  • Monitor Search Console
  • Fix errors promptly

---

*Content truncated.*

  • →When the schema does not accurately represent page content
  • →When marking up content that does not exist on the page
  • →For broader SEO issues beyond structured data

Limitations

  • →Schema must accurately represent page content
  • →Only use markup Google supports
  • →Schema must match visible content

How it compares

This skill provides specific JSON-LD examples and placement instructions for various schema types, unlike a manual approach that requires extensive research.
