How to Generate JSON-LD Schema Markup for SEO
Add structured data to any webpage and unlock rich snippets in Google Search — star ratings, FAQs, breadcrumbs and more. No coding skills required.
What is JSON-LD schema markup?
Schema markup (structured data) is a vocabulary of code that you add to your webpages to help search engines understand your content. Instead of Google guessing whether your page is an article, a recipe, a product, or a local business — schema tells it explicitly.
JSON-LD (JavaScript Object Notation for Linked Data) is the format Google recommends for implementing schema. It looks like this:
{
"@context": "https://schema.org",
"@type": "FAQPage",
"mainEntity": [{
"@type": "Question",
"name": "What is JSON-LD?",
"acceptedAnswer": {
"@type": "Answer",
"text": "A structured data format recommended by Google."
}
}]
}
This code sits inside a <script type="application/ld+json"> tag in your page's <head> — completely separate from your visible content, so it never affects your design or performance.
Why does schema markup matter for SEO?
Structured data doesn't directly improve your rankings, but it unlocks rich results in Google Search — the enhanced listing formats that get dramatically higher click-through rates:
| Schema Type | Rich Result in Google | CTR Boost (avg.) |
|---|---|---|
| FAQPage | Expandable Q&A directly in SERP | +20–30% |
| Article | Date, author, breadcrumbs shown | +15% |
| Product | Price, stock, star ratings | +25–40% |
| LocalBusiness | Map, hours, phone in Knowledge Panel | +30% |
| BreadcrumbList | Site path shown instead of URL | +10–15% |
| SoftwareApplication | Rating, OS, price in sidebar | +20% |
Even without rich results, schema helps Google better understand your content — which correlates with stronger topical authority and more consistent keyword coverage.
Step-by-step: generating JSON-LD schema markup
Step 1 — Choose your schema type
Open our JSON-LD Generator. Select the type of structured data you need: Article, FAQPage, LocalBusiness, Product, BreadcrumbList, or SoftwareApplication.
Step 2 — Fill in your details
Complete the form fields — name, description, URL, date, author, etc. The form adapts to show only the fields relevant to your chosen schema type. No need to know the property names by heart.
Step 3 — Copy the generated code
The tool generates valid, Google-compliant JSON-LD in real time as you type. Click "Copy to Clipboard" to get the complete <script> tag ready to paste.
Step 4 — Paste it into your webpage
Add the <script type="application/ld+json"> block inside your page's <head> tag. Works with WordPress (Theme Editor or Rank Math/Yoast), Webflow, Shopify, Squarespace, custom HTML — any platform.
Step 5 — Validate with Google's Rich Results Test
Paste your page URL into Google's Rich Results Test to confirm the markup is valid and eligible for rich results. Google typically picks up schema within 1–2 crawl cycles.
Which schema type should I use?
Here's a quick reference for the most common use cases:
- Blog post or news article → use
ArticleorNewsArticle - FAQ section on any page → use
FAQPage(huge SERP real estate) - Online tool or software → use
SoftwareApplication - Physical business with a location → use
LocalBusiness - Product page on an e-commerce site → use
ProductwithOffer - Any page on a site with a clear hierarchy → add
BreadcrumbListalongside any other type
You can stack multiple JSON-LD blocks on the same page — for example, an Article + BreadcrumbList + FAQPage all on a single blog post.
Frequently asked questions
What is JSON-LD and why does Google prefer it over Microdata?
JSON-LD is a self-contained data block in a <script> tag. Microdata embeds attributes directly inside your HTML elements. Google recommends JSON-LD because it's easier to maintain — if you update the structured data, you only change the script block without touching the HTML structure.
Does schema markup directly improve rankings?
Not directly — it's not a confirmed ranking signal. But it enables rich results which boost CTR significantly. Higher CTR on the same keyword can eventually improve rankings through behavioral signals.
Where exactly do I paste the JSON-LD code?
Inside the <head> section of your HTML, before the closing </head> tag. In WordPress, you can add it via a plugin like Rank Math, or by editing your theme's header.php.
How long until Google shows rich results?
Typically 1–4 weeks. Google needs to recrawl and reindex the page first. You can request indexing in Google Search Console to speed it up.
Is the generator free to use?
Yes, completely free — no account, no limit. The tool runs entirely in your browser, so your data stays on your device.
