What structured data does for a page
Structured data is a standardized way of describing a page's content in a format machines can parse unambiguously, using a shared vocabulary maintained by schema.org and adopted by every major search engine. Rather than a search engine having to guess from surrounding text that a number is a price or that a name is an author, structured data states it explicitly: this is a Product, its price is this, its currency is this. That precision is what allows search engines to build enhanced result features — star ratings, FAQ dropdowns directly in search results, recipe cards with cook times, and similar rich display elements — that a plain, unstructured page simply isn't eligible for.
This generator produces the JSON-LD format specifically, which is the format search engines explicitly recommend over the older microdata and RDFa alternatives, mainly because it lives in a single, self-contained script tag rather than being woven attribute-by-attribute through the visible HTML, making it far easier to add, update, or remove without touching the rest of a page's markup.
Choosing the right schema type
Article schema fits blog posts, news pieces, and similar editorial content, and is what allows search engines to reliably attribute a byline and publish date to a piece of writing. Product schema is built for individual product pages and is one of the most consequential types to get right, since accurate price and availability data feeds directly into shopping-related search features. FAQ schema marks up a genuine list of question-and-answer pairs already visible on the page — using it for content that isn't actually presented as a Q&A on the page itself risks being flagged as misleading structured data rather than a helpful description of real content. Local Business schema is for a physical business location, feeding directly into local search and map-based results, and Breadcrumb schema describes a page's position in a site's navigational hierarchy, which can influence how the URL path is displayed in search results.
A critical rule: structured data must match the visible page
Every schema type generated here should describe content that's actually visible on the page it's added to. Search engines have explicit guidelines against structured data that describes something different from, or more impressive than, what a visitor actually sees — marking up a five-star rating that isn't shown anywhere on the page, or FAQ content that doesn't appear as visible text, is treated as a violation of those guidelines and can result in the structured data being ignored or, in more serious cases, being treated as a broader trust signal issue for the site. Use this generator to accurately describe real content, not to add data you wish were true.
Adding the generated code to your page
Paste the generated script tag anywhere inside your page's head or body section — placement doesn't affect how it's read by search engines, since JSON-LD is intentionally self-contained and doesn't need to sit near the content it describes. After adding it to a live page, it's worth validating the result with a structured data testing tool to confirm it parses correctly and is recognized as the intended type, since a small typo in a field name can silently cause an entire block to be ignored.
