What Schema Markup Info is

Schema Markup Info is a free web tool for creating schema markup and checking structured data. Its browser-based generator creates JSON-LD, with forms for types such as Product, LocalBusiness, Article, FAQ, WebSite, and HowTo. Product output can be copied or downloaded as a script tag, JSON-LD, WordPress, or Tag Manager format. The validator parses JSON-LD, microdata, and RDFa into an internal graph, then checks documented Google Search feature requirements and whether marked-up values match visible page content. Reports can include values, page location, visibility, and confidence. The validator can follow redirects and render JavaScript-built pages. For site checks, the audit reads a sitemap, crawls reachable pages, and groups findings by defect; crawls have a page budget and a 20-minute limit. The rule registry covers 19 Google Search features, with all entries marked provisional and requirements last verified on 2026-08-29. The tool says it cannot determine whether Google will show a rich result or what Google itself sees. The generator requires no account, and the site states it has no advertising trackers.

Who it suits

The tool suits people checking structured data on individual pages or auditing a website for grouped defects. Its maker also describes use with staging pages, pages behind a login, and undeployed markup pasted as HTML.

Questions

Is Schema Markup Info free?

Yes. The maker describes its generator and validator as free tools, with a free plan and no free trial.

Which markup formats can the validator check?

It parses JSON-LD, microdata, and RDFa into an internal graph before checking rules.

Can it guarantee a Google rich result?

No. The maker says the tool cannot determine whether Google will show a rich result, and structured data does not guarantee one or improve ranking.

Does the generator need an account?

No. The maker says the generator requires no account.

What integrations or export options does it offer?

The site links to Google’s Rich Results Test and the Schema.org validator. Product output options include script tag, JSON-LD, WordPress, and Tag Manager.

The generator runs in the browser and sends nothing typed into it. The validator sends a submitted URL to the service; pasted HTML is processed for a report and not retained.
