What is JSON-LD schema markup and why does it matter?

JSON-LD is Google's preferred format for structured data. It tells search engines exactly what your content means, enabling rich results like FAQ dropdowns, star ratings, and how-to step carousels in Google Search.

Where do I paste the JSON-LD code?

Paste the script type application/ld+json block into your page's head section. In WordPress, use Rank Math's Custom Schema field, the Insert Headers and Footers plugin, or paste directly into header.php.

Can I have multiple schema types on one page?

Yes. It is common to stack multiple schema types on a single page — for example, Article, BreadcrumbList, and FAQPage all on the same blog post. Each can live in its own script block.

Who needs a schema markup generator?

Structured data is no longer optional. Google uses it to build rich results — star ratings, FAQs, how-to steps, sitelinks — directly in search. Any page without it is leaving visibility on the table.

How to use the Schema Markup Generator

Generating valid structured data takes under two minutes with this tool. Follow these steps to go from blank page to production-ready JSON-LD.

Select your schema type

Click the schema type that best describes your page — Article for blog posts, FAQPage for Q&A pages, Product for e-commerce listings, LocalBusiness for location-based businesses, and so on.

Fill in the common fields

Enter the page URL, title/name, and description. These map directly to @id, name, and description in the output. Use your canonical URL for best results.

Complete the type-specific fields

Each schema type reveals its own additional fields — author and publish date for articles, price and currency for products, address and phone for local businesses. Fill in as many as you have.

Generate and review

Click Generate JSON-LD. The output panel shows syntax-highlighted, validated JSON-LD. The validator checks for required fields and warns you if any are missing.

Copy or download, then paste into your page

Use Copy <script> tag to get the full <script type="application/ld+json"> block ready to paste into your page’s <head>. Or download the .json file for reference. Then test in Google’s Rich Results Test.

Schema types and their SEO impact

Not all schema types unlock rich results. Here’s a quick reference showing which types are supported by Google’s rich results feature, how hard they are to implement, and what you get in return.

Schema Type	Rich Result	SEO Impact	Complexity	Best For
`Article`	Byline, date in SERPs	High	Low	Blog posts, news articles
`FAQPage`	Accordion Q&A in SERPs	High	Medium	Help pages, landing pages
`HowTo`	Numbered steps in SERPs	High	Medium	Tutorials, recipes, DIY
`Product`	Price, stars, availability	High	Medium	E-commerce product pages
`LocalBusiness`	Knowledge Panel data	High	Low	Physical business locations
`WebApplication`	App name, category, price	Medium	Low	SaaS tools, browser utilities
`Organization`	Brand Knowledge Panel	Medium	Low	Homepage, About page
`WebPage`	Basic page metadata	Medium	Very Low	Any generic page
`BreadcrumbList`	Breadcrumb path in URL	Medium	Low	Multi-level site structures

Schema markup FAQ

JSON-LD (JavaScript Object Notation for Linked Data) is Google’s preferred format for structured data. It sits inside a <script type="application/ld+json"> tag in your page’s <head> and tells search engines exactly what your content means — not just what it says. When Google can interpret your content’s context, it can serve rich results: star ratings, FAQ dropdowns, how-to step carousels, and more. These rich results significantly increase click-through rates from search, often by 20–30% for supported schema types.

Yes, for most use cases. Google explicitly recommends JSON-LD because it doesn’t require you to modify your HTML structure — it lives in a separate script block that can be added or updated without touching your content markup. Microdata and RDFa require you to annotate every HTML element with attributes, which is error-prone and harder to maintain. Unless your CMS specifically outputs Microdata, JSON-LD is the right choice.

Not directly. Schema markup is not a confirmed ranking signal — Google has stated this clearly. What it does do is unlock rich results that increase click-through rates, which indirectly sends positive engagement signals back to Google. A page with FAQ rich results that takes up 3× the SERP space will naturally attract more clicks than a plain blue link, even at the same position. Improved CTR at scale can contribute to ranking improvements over time.

Paste the <script type="application/ld+json"> block anywhere in your page’s <head> section. In WordPress, you can use the Rank Math SEO plugin’s Schema tab (it has a Custom Schema option), paste it into your theme’s header.php, or use a plugin like Insert Headers and Footers to add it globally or per page. Avoid placing it in the <body> — while Google says it can parse it there, <head> placement is cleaner and more reliable.

Yes. It’s common and encouraged to stack multiple schema types on a single page. For example, a blog post might have Article + BreadcrumbList + FAQPage + WebPage all on the same page. Each can live in its own <script type="application/ld+json"> block, or you can combine them into a single JSON-LD array. Generate each type separately with this tool, then combine the outputs before pasting them into your page.

Use Google’s Rich Results Test — paste your URL or the raw JSON-LD code and it will show you which rich results your page is eligible for and flag any errors. Schema.org’s validator at validator.schema.org is useful for checking spec compliance, though it’s less focused on what Google actually supports. Both tools are free and require no account.

Google will ignore the schema or partially process it — neither outcome penalises your site. Schema errors are not a ranking negative signal. However, if required fields are missing (for example, Product schema without name or offers), you won’t qualify for the associated rich result. This tool validates required fields before output and warns you if something critical is missing. Fix the flagged fields and regenerate.

It depends on your setup. Yoast SEO and Rank Math both add basic schema (WebSite, WebPage, Article) automatically. However, the auto-generated output is often minimal and doesn’t cover FAQPage, HowTo, Product, or LocalBusiness types unless you explicitly configure them. Rank Math has a Schema module that supports most types through its UI, but complex schemas benefit from custom JSON-LD generated with a tool like this and pasted in manually for full control over every property.

Absolutely — this tool is completely free with no usage limits, no login, and no attribution required. Generate schema markup for as many client pages as you need. All processing happens in your browser, so no data from the fields you fill in is sent to any server. For agencies managing multiple sites, generate and save the JSON-LD files using the download button, then apply them per-page as needed.
