A schema markup generator turns plain form inputs into valid JSON-LD structured data you can paste straight into your page. Fill in a few fields, pick a type, and this free tool outputs a ready-to-use <script type="application/ld+json"> block for the schema.org types that do most of the real-world work: Organization, LocalBusiness, Article, FAQPage, Product, and BreadcrumbList. No login, no markup expertise, and everything runs in your browser so your data never leaves the page.
Structured data is how you tell search engines and AI answer engines exactly what a page is — who published it, what product it describes, what questions it answers — instead of leaving them to guess. That clarity is what makes a page eligible for rich results like review stars, FAQ accordions, and breadcrumb trails. It is also what helps Google AI Overviews, ChatGPT, and Perplexity parse your content and decide whether to cite it. JSON-LD is the format Google recommends, and it is the only output this generator produces.
Use the tool below to build clean, valid markup for a single page in seconds. Then validate it, paste it in, and move on. When you have a whole site to mark up — and need every type kept in sync as content changes — that is where the manual workflow stops scaling and Black & Gold SEO takes over.
How to use it
- 1
Choose your schema type
Select the schema.org type that matches what the page actually is: Organization for your brand identity, LocalBusiness for a physical or service-area business, Article for posts and guides, FAQPage for question-and-answer content, Product for an e-commerce detail page, or BreadcrumbList for the navigation path. Match the type to real on-page content — never mark up something that isn't there.
- 2
Fill in the fields
Enter the properties the tool asks for — name, URL, logo, address, author, price, questions and answers, and so on. The generator only requests the properties that carry weight for each type, so you don't have to memorize the schema.org vocabulary or hand-write nested objects.
- 3
Copy the generated JSON-LD
The tool instantly builds a single, valid <script type="application/ld+json"> block with the correct @context and @type, straight double quotes, and no trailing commas. Copy it with one click — everything is generated client-side, so nothing you type is sent anywhere.
- 4
Validate before you ship
Paste the markup into Google's Rich Results Test to confirm rich-result eligibility, and into the Schema Markup Validator at validator.schema.org to check it against the full schema.org vocabulary. Fix any errors first, then warnings — never publish structured data unvalidated.
- 5
Paste it into your page
Drop the script into the page's <head> or body. Keep the values matched to what's visible on the page, and re-test after any content change so your structured data stays accurate over time.
A small core of schema types covers the majority of real-world use, which is why this generator focuses on six rather than the hundreds schema.org defines. Organization establishes your brand identity site-wide; LocalBusiness adds address, phone, and hours for a physical or service-area business; Article marks up posts and guides with author and publish date; FAQPage makes question-and-answer pairs eligible for FAQ rich results; Product carries name, image, and offers for e-commerce; and BreadcrumbList describes the navigation path. Add only the types that genuinely fit the page in front of you.
It's worth being honest about what schema does and doesn't do. Structured data is not a direct ranking factor — Google has said so repeatedly. Its value is eligibility and clarity: it makes pages eligible for supported rich results and gives both classic search and AI engines an unambiguous reading of your content. Google also only renders rich results for a defined set of features, and only when the page qualifies, so valid markup for an unsupported type still adds machine-readable meaning even if it doesn't change how the listing looks.
The most common mistakes are easy to avoid with a generator: invalid JSON (curly quotes, trailing commas), marking up content that isn't actually on the page, and inconsistent entity details across pages. Use the same name and URL for your Organization everywhere, point each entity at its authoritative profiles with sameAs, and re-validate after every change. The hard part isn't generating one block — it's keeping dozens of them correct and in sync as your site grows.
