How to add schema markup search engines can use
What schema markup does
Schema markup is a block of structured data, usually JSON-LD, that describes a page using the schema.org vocabulary. Google uses it to understand the page and, for some types, to show richer results such as prices, ratings, or, on desktop, a breadcrumb trail in place of a plain address.
It doesn't guarantee a rich result or a higher ranking. Google shows rich results only when the markup is valid, matches what visitors can see, and Google decides the result is useful for the search.
Which types to start with
Most marketing sites get the most from five types.
- Organization on your home or About page: your name, logo, and official profiles.
- Article or BlogPosting on posts and guides: headline, dates, authors, and images.
- BreadcrumbList on pages below your home page, so desktop results can show where the page sits.
- SoftwareApplication on a product page, with a price and ratings from real reviews.
- FAQPage where a page shows questions and answers. Google no longer shows FAQ rich results, but the markup is still valid schema.org.
Rules that keep markup trustworthy
Mark up only what visitors can see on the page. Hidden or invented details, such as ratings that don't come from real reviews, break Google's structured data policies and can cost you rich results.
- Use full addresses, starting with https://, for pages, images, and logos.
- Write dates in ISO 8601 with a time zone, such as 2026-10-17T09:00:00+01:00.
- List each author as a separate person, with a link to a page about them.
- Check the page with Google's Rich Results Test after you publish.
Frequently asked
Questions, answered.
What people ask before they use the Schema markup generator.
Code added to a page that describes its content in the schema.org vocabulary, such as who wrote an article or what an app costs. Google recommends the JSON-LD format, a short script block that sits apart from your visible content.
In a script tag of type application/ld+json, in the page's head or body. Google reads it in either place. Each page should describe its own content.
Not directly. Google uses structured data to understand pages and to decide whether they can appear as rich results, which can earn more clicks. It doesn't promise a ranking boost.
Google limited FAQ rich results to a small set of government and health sites in 2023 and stopped showing them in May 2026. The markup is still valid schema.org, so there's no harm in keeping it.
Yes. Choose Check a page and enter the address. Our server fetches the public page and the tool lists every JSON-LD block it finds, with the same checks as the form. We keep the result for a few minutes so repeat checks are quick.
The Rich Results Test shows which Google results a published page qualifies for. This tool helps you write the markup in the first place and explains each problem in plain language. Write it here, then confirm it there.
