Structured Data

JSON-LD lets you describe page content in a machine-readable format that search engines understand.

Add a script Tag

Include a <script type="application/ld+json"> in svelte:head.

<svelte:head>
  {@html jsonLd}
</svelte:head>

Build the JSON

Stringify a JS object describing your page.

$: jsonLd = `<script type="application/ld+json">${JSON.stringify({
  "@context": "https://schema.org",
  "@type": "Article",
  headline: post.title
})}<\/script>`;

Schema Types

Common types: Article, Product, Recipe, Event, Organization, BreadcrumbList.

SEO Benefits

Rich snippets in search results: stars, prices, breadcrumbs, FAQ accordions.

Google Search Console

Check Google's structured data testing tool to validate your JSON-LD.

Multiple Schemas

You can include multiple JSON-LD blocks for different schemas on one page.

Avoid Spam

Only describe what is actually on the page; manipulating schema can lead to manual penalties.

Maintainability

Build a helper that takes data and returns JSON-LD strings for common page types.

Localization

Translate fields like name and description per locale for international SEO.

Combine With OG

JSON-LD and OG tags complement each other; both improve discovery and sharing.
