What is a JSON-LD generator and what does ld+json mean?

It creates structured data blocks you can copy straight into your site. In HTML, that block sits inside a ` ` tag—often shortened to ld+json—so Google understands exactly what your page represents.

How is this different from the schema markup generator?

It is not a second engine. Both pages share the same types and builder. Use this URL when you want a JSON-LD-named tool; use schema markup when that is the phrase you search for.

Do I wrap the output in a script tag?

The download is the JSON object only. In HTML you still wrap it: a script of type application/ld+json, then the object. Do not nest a second script.

Which types can I emit?

FAQPage, HowTo, Article, Product, LocalBusiness, BreadcrumbList, and Organization — the same set as the schema markup generator.

Is the JSON sent to a crawler from here?

No. Preview is local. Search engines only see markup after you publish it on a page they can fetch.

How do I emit the same JSON-LD without this form?

Use this page or the schema markup generator — they share buildSchemaJsonLd. There is no API. Compact empty strings/arrays. FAQPage needs both question and answer. HowToStep position starts at 1. Product Offer only if price or url is set (currency defaults to USD). Organization sameAs is newline-split. Serialize with JSON.stringify(..., null, 2) and a trailing newline.

Should I place the JSON-LD script tag in the head or body of my HTML?

Google supports JSON-LD script blocks in either the or section of your HTML document. Placing structured data inside the tag is standard practice because search engine parsers discover page metadata earlier in document processing.

Can I have multiple JSON-LD script tags on the same webpage?

Yes. You can include multiple independent elements on a single page, such as combining an Organization schema with an FAQPage or BreadcrumbList. Alternatively, entities can be grouped under a single @graph array.

This is the JSON-LD-focused entry for the same schema types as the markup generator. Fill the fields, copy the object, and paste it into a script of type application/ld+json. Review it in Google’s testers before you ship.
