How to Use This Schema Markup Generator
Structured data helps search engines understand your page content and can unlock rich results — enhanced listings with star ratings, images, FAQs, pricing, and more. This free generator walks you through creating valid JSON-LD markup without needing to write any code yourself.
- Pick a schema type from the dropdown. Each type is grouped by category and tagged with its Google support status so you know which ones can trigger rich results.
- Fill in the required fields first, then expand Recommended and Advanced sections for deeper coverage. The completion meter and live validation update as you type.
- Review the JSON-LD preview on the right (or tap "Preview & Validate" on mobile). The syntax-highlighted output updates in real time.
- Copy or download the finished markup, then paste it into your site using the CMS guidance panel below the preview.
You can also save drafts to your browser, import existing JSON-LD for editing, and load example data to see how a complete schema looks before starting from scratch.
Schema.org vs. Google Rich Results
Schema.org is a collaborative vocabulary maintained by Google, Microsoft, Yahoo, and Yandex. Any website can use it, and search engines may use it to better understand page content. However, not every Schema.org type triggers a visible rich result in Google Search.
Google documents specific types — like Article, FAQ, Product, Recipe, and LocalBusiness — that are eligible for enhanced display. This generator marks each schema with its current support level: "Google Supported" means Google has documented the type for a search feature, "Schema.org" means it is valid structured data but may not trigger visible rich results, and "Advanced / Restricted" means special eligibility or additional setup is needed.
Even when a type does not trigger a rich result today, adding accurate structured data improves machine readability and future-proofs your content for new search features.
Common Schema Markup Mistakes
Getting structured data right matters — invalid or misleading markup can result in manual actions from Google or simply be ignored. Here are the most frequent issues:
- Missing required properties: Every schema type has properties that Google considers mandatory. Without them, the markup is technically valid JSON-LD but will not qualify for rich results.
- Marking up invisible content: Structured data must reflect content that users can actually see on the page. Adding reviews or FAQs that are not visible to visitors violates Google's guidelines.
- Using the wrong type: A blog post is an Article, not a WebPage. A physical store is a LocalBusiness, not an Organization. Choosing the most specific applicable type improves accuracy.
- Stale or inaccurate data: Prices, ratings, availability, and event dates must match what is currently on the page. Outdated structured data erodes trust and can lead to removal from rich results.
- Forgetting @context: JSON-LD requires
"@context": "https://schema.org"at the top level. This generator adds it automatically, but manually written markup often omits it.
Where to Place JSON-LD on Your Site
JSON-LD goes inside a <script type="application/ld+json"> tag, typically in the <head> of your HTML. Unlike Microdata or RDFa, it does not need to be interleaved with visible page content — it can sit in a single block anywhere on the page, though the head is conventional.
Most CMS platforms provide a way to inject code into the head. WordPress users can paste the script into a theme header or use a plugin like Yoast, RankMath, or Insert Headers and Footers. Shopify has a dedicated theme.liquid head section. Wix and Squarespace provide custom code injection in their site settings. The CMS guidance panel in this tool gives specific steps for each platform.
Frequently Asked Questions
Is this tool really free?
Yes. Everything runs in your browser — no data is sent to any server, no account is needed, and there are no usage limits. Your form data stays on your device.
How do I test my structured data?
After deploying, paste your page URL into Google's Rich Results Test or the Schema.org Validator. Both tools parse your page and flag errors. This generator also includes a built-in validation panel that checks for missing required fields, structural issues, and rich-result readiness before you even deploy.
Can I use multiple schema types on one page?
Yes. You can include multiple JSON-LD blocks on a single page — for example, an Article schema and a FAQ schema on a blog post with an FAQ section. Each block is a separate script tag with its own @context and @type.
Does structured data directly improve rankings?
Structured data is not a direct ranking factor. However, rich results can significantly improve click-through rates by making your listing more prominent and informative. Higher CTR can indirectly benefit rankings over time.
