Free Schema Markup Generator (+ Guide)

What is schema markup?

Schema markup is a block of code that tells search engines what a page is: an article, a product, an app or an event. It's usually written as JSON-LD, a single script block in the page's <head>.

Google uses it for rich results, like a price, a rating or a breadcrumb trail under a page's title.

Which schema types still work in Google

Each type below was checked against its own page in Google's documentation. The builder shows the same status the moment you pick a type.

Stars from reviews are only for reviews of something else. Google won't show them when a business marks up reviews about itself.

Google's full list lives in its search gallery.

Google stopped showing FAQ rich results

FAQ rich results used to be the easiest win in SEO. Google limited them to well-known government and health sites in 2023, then removed them for everyone in May 2026.

FAQPage markup does no harm, but it earns nothing in Google Search anymore. HowTo is gone from Google's list too.

Valid doesn't mean shown

Google is clear about it: it "does not guarantee that your structured data will show up in search results, even if your page is marked up correctly." Valid markup makes a page eligible, and Google decides the rest.

Its first rule matters just as much: "Don't mark up content that is not visible to readers of the page." The builder only writes the fields you fill in, so mark up what's really there.

Does schema help with AI search?

Google's AI optimization guide answers it directly: "Structured data isn't required for generative AI search, and there's no special schema.org markup you need to add."

It still says to keep using it, because "it helps with being eligible for rich results on Google Search."

How to add schema markup to your site

Most site builders and SEO plugins have a place for code in the <head>. Paste the block there, publish, then test the live address.

Check the markup you already have

Open the Check a page tab and type any address. You'll see every JSON-LD block on the page, the types in it, and what to fix.

It follows the links inside a block too, like a profile page that points to the person it's about. That's where most checkers give up.

3 mistakes to avoid

• A free app with no price: Google's software app rules need a price, so set it to 0
• FAQ markup for a rich result: Google no longer shows them
• An online event for Google's event listing: Google's event rules need a venue with a street address
