How to generate JSON-LD schema markup

Schema markup is a machine-readable description of what a page is about, written as JSON-LD in a script tag. Search engines use it to understand your content and, when the required properties are present, to show a richer result.

The markup is generated in your browser. Choose the type that genuinely matches the page, fill in the core properties, and validate the result before you ship it.

  • Choose the schema type that matches the page: Organization for a homepage, Article for a post, Product for an item.
  • Fill in the name or headline, the URL, the description, and the image.
  • Add any further properties as key and value pairs, one per line, using the exact schema.org property names.
  • Copy the generated script tag into the head of your page.
  • Run the live URL through Google's Rich Results Test, which will tell you which required properties are still missing for a rich result.
Tips

Getting a better result out of Schema Markup Generator

Specific settings and thresholds, not general advice.

  • Structured data must describe what is actually on the page. Marking up a review, a price, or an event that a visitor cannot see is a spam violation, and Google issues manual actions for it. The markup is a machine-readable summary of the page, not an addition to it.
  • A minimal, valid schema object often does not qualify for a rich result. Rich results have required properties: a Product needs an offer, a review, or an aggregate rating; an Article needs a headline, an image, and a publication date. Valid is not the same as eligible, and this generator produces the former.
  • Structured data is not a ranking factor. It makes you eligible for a richer presentation in the results, which lifts click-through rate, and that is the whole mechanism. Adding schema to a page that nobody ranks for will change nothing.
  • JSON-LD is the format Google recommends, and it has a real practical advantage over microdata: it sits in one script block rather than being woven through your markup, so it does not break when a designer restructures the page.
  • Test everything in Google's Rich Results Test, which tells you whether you qualify for a rich result, and in the schema.org validator, which tells you whether your syntax is correct. Those are two different questions and you need both answers.
Limits

What Schema Markup Generator does not do

The honest boundary, so you do not lose time finding it yourself.

  • It offers eight schema types, and schema.org defines more than 800, so anything outside the common set has to be written by hand.
  • It does not check required properties, so it will happily produce a Product with no offer, which is valid JSON-LD and ineligible for any rich result.
  • It cannot build nested entities or an @graph, so relationships such as an article's author being an Organization with its own logo need manual editing.
  • It does not generate sameAs arrays or @id references, which are what tie your entities to a knowledge graph.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Will adding this schema improve my rankings?

Not directly. Google has been consistent that structured data is not a ranking signal. What it does is make a page eligible for a rich result, which is a visually richer entry in the results page: star ratings, a price, a recipe image, a breadcrumb trail. Those enhancements can lift click-through rate substantially, which is a real benefit, but they only apply to a page that already appears in the results. Schema is presentation, not position.

My markup validates but I get no rich result. Why?

Validation and eligibility are separate tests. The schema.org validator checks that your JSON-LD is well-formed and uses real properties. Google's Rich Results Test checks whether you have supplied the specific properties that a given rich result requires, which is a much narrower bar. A Product without an offer, a review, or an aggregate rating is perfectly valid schema and will never produce a rich result. Run the Rich Results Test, and it will list exactly which required fields are missing.

Can I mark up content that is not visible on the page?

No. Google's structured data guidelines require the marked-up content to be visible to the user, and marking up ratings, prices, or FAQs that do not appear on the page is one of the clearest ways to earn a manual action. The penalty removes your rich results entirely and can affect the site more broadly. The mental model to hold is that structured data annotates the page rather than extending it.

Where does the JSON-LD script go?

Anywhere in the document, though the head is conventional. Google reads it from either the head or the body, and it does not need to sit near the content it describes, which is precisely the advantage of JSON-LD over microdata. If the page is client-rendered, make sure the script is in the server's HTML response, because although Google does render JavaScript, doing so is slower and less reliable than reading it from the initial payload.

Is my data sent anywhere?

No. The JSON-LD is assembled in your browser from the values you type. Nothing about an unreleased product, price, or event is transmitted.
