schema

Search engines cannot work out what a page is about just by reading it, so pages carry hidden labels that spell it out — this writes those labels for your pages and checks that Google accepts them.

WHEN TO USE

SCOPE

USE FOR

Mark up a product page so its price and rating can show in the search result.
Set up your frequently asked questions so they can appear directly in search results.
Combine several labels on one page instead of adding each one separately.
Fix a labelling error that Google Search Console is reporting on your pages.
Label the navigation trail on a page so it matches how your site is organised.

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

Check for product marketing context first: If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before implementing schema, understand:

Page Type - What kind of page? What's the primary content? What rich results are possible?
Current State - Any existing schema? Errors in implementation? Which rich results already appearing?
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

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: See references/schema-examples.md

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

You can combine multiple schema types on one page using @graph:

{
  "@context": "https://schema.org",
  "@graph": [
    { "@type": "Organization", ... },
    { "@type": "WebSite", ... },
    { "@type": "BreadcrumbList", ... }
  ]
}

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

Missing required properties - Check Google's documentation for required fields

Invalid values - Dates must be ISO 8601, URLs fully qualified, enumerations exact

Mismatch with page content - Schema doesn't match visible content

Implementation

Static Sites

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

Dynamic Sites (React, Next.js)

Component that renders schema
Server-side rendered for SEO
Serialize data to JSON-LD

CMS / WordPress

Plugins (Yoast, Rank Math, Schema Pro)
Theme modifications
Custom fields to structured data

Output Format

Schema Implementation

// Full JSON-LD code block
{
  "@context": "https://schema.org",
  "@type": "...",
  // Complete markup
}

Testing Checklist

Validates in Rich Results Test
No errors or warnings

All required properties included

Task-Specific Questions

What type of page is this?
What rich results are you hoping to achieve?
What data is available to populate the schema?
Is there existing schema on the page?
What's your tech stack?

This skill ships inside the Marketing Skills for AI Agents plugin.

Install just this skill

Run this outside your AI tool, using Node.js 22.20.0 or newer. Skills CLI 1.7.2 skips skill selection; prompts cancel installation without an interactive terminal. If choosing Project when asked about installation scope, open your project's folder before running this.

Install checklist

Check selected tools if a picker appears; Claude Code may be unchecked under Additional agents. ↑/↓ moves, Space toggles selections, Enter confirms.
Without a tool picker, check Installing to: for your intended tool. Stop if it names a different tool.
If asked, choose Symlink (Recommended) for shared files or Copy to all agents for separate copies; review the summary before confirming installation.
Install the find-skills skill? defaults to Yes, adding another skill for all projects. Choose No if you don't want that extra installation.

Skills CLI 1.7.2 sends install data to skills.sh by default, including the source, skill names, target tools and file details; GitHub sources are reported only when GitHub confirms the repository is public, while other remote sources can also be reported. Confirmed-public GitHub sources also trigger a security-audit request. Before installing, set the environment variable DO_NOT_TRACK=1 or DISABLE_TELEMETRY=1 to disable both.

npx skills add coreyhaines31/marketingskills --skill "schema" --full-depth

After installing for Claude Code, open it in the installation project if you chose Project; Global makes the skill available across projects on this computer. Once Claude Code loads the skill, its description helps Claude decide when to use it.

If installation created a top-level skills folder that did not exist when your Claude Code session started, run /reload-skills in that session. Run it again after later changes in that folder.

Install the whole plugin

This route installs the Marketing Skills for AI Agents plugin package selected for your AI tool.

Add the marketplace, then install the plugin

Type both lines inside a Claude Code session, not at your shell prompt. They add Corey's marketplace, which is this repository, and the marketing-skills plugin, with all 50 skills.

/plugin marketplace add coreyhaines31/marketingskills

02
```
/plugin install marketing-skills
```

Installation and loading

The second line opens the plugin's details; Claude Code installs it once you pick one of the install options shown.

Good to know

/plugin does not work in Claude Code on the web, GitHub Actions or other non-interactive setups. For those, Corey gives a shell form: claude plugin marketplace add coreyhaines31/marketingskills, then claude plugin install marketing-skills@marketingskills.

Add the marketplace, then pick the plugin in Codex

Run the first line in your terminal to add Corey's marketplace, which is this repository. Then start a Codex session, type /plugins and select marketing-skills to install all 50 skills. To get new releases later, run codex plugin marketplace upgrade.

codex plugin marketplace add coreyhaines31/marketingskills

02
```
/plugins
```
