Schema markup generator: valid JSON-LD from the fields you fill

The seogeoaeo.ai schema markup generator turns a schema type and a short form of fields into JSON-LD you can paste straight into a page. Each run costs 3 credits, fetches nothing, and previews the result against the validator rules, so you can spot gaps before the code ships.

What you get from one run

You choose a type, fill in what you know, and get back a block of JSON-LD with a preview against the validator rules. The generator never visits your page, which makes it safe to use on drafts, staging content or a page that does not exist yet.

The type list covers the markup most sites need:

Only the type is required. The rest of the form follows the type: headline, author and publish dates for an article; price, currency and rating for a product; start date, end date and location for an event; steps and ingredients for a recipe.

A worked example

Say you run a small app and want SoftwareApplication markup on its landing page. You would pick the type, then enter the name, page URL, application category, operating system, price and currency. A SoftwareApplication block with those fields follows the standard schema.org shape, roughly:

{
  "@context": "https://schema.org",
  "@type": "SoftwareApplication",
  "name": "Example App",
  "url": "https://example.com/app",
  "applicationCategory": "BusinessApplication",
  "operatingSystem": "Web",
  "offers": { "@type": "Offer", "price": "0", "priceCurrency": "USD" }
}

Read the preview before you copy the block. Adding a description or a rating now is cheaper than finding the gap after a failed test. Keep every value honest too: the price, rating and dates in the markup should match what the page itself shows.

Placing it on the page

Wrap the JSON-LD in a script tag with type="application/ld+json" and put it in the page's HTML. Google accepts it in the head or the body, and it recommends JSON-LD over Microdata and RDFa where your setup allows.

Two rules from Google's guidelines matter here. Every value must describe something a visitor can see on that page, and the markup has to carry the required properties for the rich result you want. Even then, Google says valid markup makes a page eligible for a rich result; it does not promise one.

Checking the live page

Once the page is deployed, run the Schema Markup Checker on its URL. It reports blocks that fail to parse, missing required and recommended properties, and types the page should add. That last part fills the one gap in the generator, which does not pick a type for you.

What it does not do

The generator is a builder, not an advisor. It does not recommend types, crawl a site, or stand in for Google's Rich Results Test. For Organization, FAQ and breadcrumb markup there are dedicated builders at the same price with fields shaped for those jobs.

If you only need one block once and do not mind checking it by hand, a free form-based generator will do. The reason to use this one is the preview and the path to a checker on the same account, plus the option to run it from an AI agent over REST or MCP with a workspace API key.

Who it suits

It fits a marketer filling in markup for a handful of key pages, a developer who wants a correct block to drop into a template, and an agent working through a site page by page. It suits a large catalogue less well: thousands of product pages should get their markup from the database behind the template, with the generator used once to settle the shape.

How to start

Open the schema markup generator, pick a type, fill the fields, and sign in to generate. The price shows before the run, and a run that fails costs nothing.
