What it does
Guides implementation of Schema.org structured data (JSON-LD) for rich snippets, enhanced search results, and Generative Engine Optimization (GEO).
How it works
- Emphasizes using JSON-LD in the
<head>with@context,@type, and stable@idto connect entities (e.g., Organization, WebSite) and to align with visible content. - Recommends selecting the most specific schema type that fits page content (e.g., Recipe, JobPosting, Event, SoftwareApplication, Product, FAQPage, HowTo, Article, NewsArticle).
- Provides required properties for BlogPosting/Article types (headline, image, datePublished, author, publisher) and suggests optional properties (dateModified, description, mainEntityOfPage).
- Describes BreadcrumbList as a dedicated JSON-LD structure matching visible breadcrumbs, with absolute URLs and sequential positions.
- Advises validation using Rich Results Test and Schema Markup Validator.
- Highlights GEO relevance for AI search visibility with key types (Organization, Person/Author, WebSite, WebPage, FAQPage, HowTo, Article, Product, AggregateRating).
- Outlines workflow steps: identify page type, content entities, and goals (rich snippets, AI visibility, Knowledge Panel).
When to use it
Not specified as conditional triggers beyond general usage guidance for content types and SERP features.
What it can touch
Not specified beyond recommending JSON-LD in the head and linking entities via @id.
Caveats
Not specified in detail beyond general guidance; notes that HowTo is deprecated for Google rich results as of Sep 2023, and that type suitability depends on content matching page purpose.

How do I install it?
Run `npx skills add kostja94/marketing-skills --skill schema --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From kostja94/marketing-skills, a repository with 848 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
