Google Rich Results Test vs Schemantra (2026): which should you pick?

Pick Google Rich Results Test if

• Fits if you're checking structured data before a page goes live
• Works for finding out why a rich result stopped showing for a page

Look elsewhere if

• Skip it if you need general schema.org checks, as it only knows Google's rich result types
• Not for you if the page is behind a login, firewall or robots.txt block, unless you paste the code or use a tunnel
• Watch out: passing the test doesn't mean Google will show the rich result, as it picks layouts per search
• Watch out: shared links and saved history last about 90 days, and anyone with the link can open them

Pick Schemantra if

• Fits if you need a schema.org type that Google's rich result tools don't cover
• Works for mapping how the entities on a page relate before you write the markup

Look elsewhere if

• Watch out: it's still labeled a beta, the footer copyright reads 2022 and the newest blog posts are from March 2024
• Not for you if you want markup tested, as it only writes it
• Too light for sites that need markup added and monitored, as you paste it in yourself and nothing is checked later
• Skip it if you don't want an account, which is needed to create and save schemas

Google Rich Results Test

• Checks only the rich result types Google Search supports; Google points to the Schema Markup Validator for general schema.org checks.
• Pages behind a firewall or login, or blocked by robots.txt, cannot be tested by URL; you need a tunnel or a code snippet.
• A passing test does not guarantee a rich result: Google says it chooses result layouts per search.
• Shared results links and saved test history last only about 90 days, and anyone with a bookmark can open it.

Schemantra

• It is labeled as a beta; the footer copyright reads 2022 and the newest blog posts date from March 2024.
• It only writes markup: you add the JSON-LD to your pages yourself or through a tag manager, and nothing is monitored afterward.
• An account is needed to create and save schemas.
• Custom ontology building is offered as a service, with no prices shown.

Google Rich Results Test

Test a URL or a code snippet

Enter a public URL, or paste code and edit and rerun it as often as needed; JSON-LD, RDFa and Microdata are supported.

Rich result detection

Lists the rich result types found, such as Article, Breadcrumb, Event, Job posting, Product snippet, Recipe and Review snippet, with each item's errors and warnings.

Crawl checks

Reports whether Google could crawl and fetch the page, whether robots.txt allows it, and which page resources failed to load.

Search result preview

For some rich result types, shows how the result might look in Google Search on desktop and mobile.

Code explorer

Clicking an error opens the rendered source at the line in question.

Shareable results and history

Share a results link that anyone can open, and bookmark runs to keep a test history, each kept for about 90 days.

Schemantra

The full schema.org vocabulary

Its guide lists 1,353 schema types and 1,448 properties, so less common types can be built as well as the ones Google uses for rich results.

Sub-schemas and linked entities

Properties that are themselves types, such as an organization's founder as a Person, are added as sub-schemas linked to the main entity.

Knowledge graph view

Shows the entities on a page and how they relate to the main one as a diagram while you build.

Industry starting points

Lists the usual types for local businesses, healthcare, real estate, ecommerce, car dealers, airlines, hotels and publishers.
