Schema Markup Generator
Create JSON-LD for common website content, then validate its JSON syntax in your browser. Choose a schema type, add facts that match the visible page and copy the finished markup.
Generate JSON-LD
Add accurate information from the page you are marking up. Optional fields stay out of the output when left blank.
JSON-LD script
Structured data should describe content visible on the page. Valid JSON does not guarantee eligibility for a search feature or a rich result.
Validate existing JSON-LD
Paste a JSON object or a full application/ld+json script. This checks JSON syntax and common top-level fields locally.
Nothing is sent to a validation service.
How to use the Schema Markup Generator
- Choose a schema type from the dropdown — Person, Organization, WebSite, Service, Article, FAQPage, BreadcrumbList, or Product.
- Fill in the fields for your page (name, URLs, dates, prices, and FAQ questions with answers), leaving blanks you cannot verify — blank fields are left out of the output.
- Click Generate schema markup, then use Copy markup to grab the finished JSON-LD script for your page.
- Paste existing code into the Validate existing JSON-LD panel and click Validate JSON-LD to check its syntax before publishing.
Why it matters
Structured data translates your page into a format search engines understand precisely: who you are, what you offer, when content was published, and how pages connect. That clarity feeds rich results, knowledge panels, and the entity graphs behind AI answers. Pages with correct schema are easier for both Google and AI systems to cite accurately. Generating clean JSON-LD removes the syntax errors that silently break markup, so your investment in content actually gets understood by machines.
Schema Markup Generator FAQs
Does valid schema guarantee a Google rich result?
No. Search features have their own eligibility rules that go beyond syntax — the markup must match visible page content, use a supported type, and meet Google's policies. The generator checks JSON structure only, so always confirm eligibility with Google's Rich Results Test after publishing and watch Search Console for enhancement reports.
Should I fill in every optional field?
No. Add only accurate values that describe the page or entity, and leave anything you cannot verify blank — the tool omits empty fields automatically. Do not mark up information visitors cannot see on the page, since mismatched markup can disqualify you from rich results.
Which schema types does the generator support?
Person, Organization, WebSite (including sitelinks search box markup), WebPage, Service, Article, FAQPage with a question-and-answer builder, BreadcrumbList, and Product with brand, SKU, price, currency, and availability. These cover the most common pages: homepages, service pages, blog posts, FAQs, and product pages.
Does this tool send my content to a server?
No. Generation and the JSON syntax check both run locally in your browser, and nothing you type is transmitted or stored. That keeps client details and unpublished drafts private while you build markup, and it means the tool works the same way whether you are on a fast connection or not.
