Should I use JSON-LD or microdata?

JSON-LD. Google recommends it, and it sits in one block instead of being spread through your HTML.

Yes, by adding more than one script block or using @graph. Keep each one accurate to what's on the page.

Create schema.org structured data in JSON-LD for the five types most sites need. Pick a type, fill in the fields, and copy a script tag ready to paste into your page's head or body.

How to use the Schema markup generator

Choose the schema type that matches the page.
Fill in the fields; empty ones are left out.
Copy the JSON-LD and paste it into the page, then test it with our schema checker.

Which type to use

Organization on your homepage or about page. SoftwareApplication for a SaaS or app page, with its price. Product for something you sell. Article for blog posts and guides. LocalBusiness if customers visit an address.

Why structured data matters now

Google uses it for rich results, and AI answer engines use it to understand what a page is about: the product name, price, category and who makes it. Clean markup makes your facts easier to quote correctly.

Rules to follow

Only mark up what's visible on the page. Ratings must come from real reviews shown there. Keep prices and availability current. One main entity per page is clearer than several competing ones.
