The record

Purpose: Schema Markup Info provides a free schema markup generator and validator for building JSON-LD and checking existing markup against Google requirements and visible page content.
Page validator: The validator checks whether marked-up values match what visitors can see and reports evidence including values, page location, visibility, and confidence.
Site audit: The site audit reads a domain’s sitemap, crawls reachable pages, and groups findings by defect; crawls have a page budget and a 20-minute limit.
Generator types: The generator offers schema markup forms for multiple types, including Product, LocalBusiness, Article, FAQ, WebSite, and HowTo.
Supported formats: The validator parses JSON-LD, microdata, and RDFa into an internal graph before checking rules.
Export options: The Product generator offers output as a script tag, JSON-LD, WordPress, or Tag Manager, with copy and download controls.
Integrations: The product links to Google’s Rich Results Test and the Schema.org validator; its generator also provides WordPress and Tag Manager output options.
Privacy: The generator runs in the browser and sends nothing the user types; the validator sends the submitted URL to the service, and pasted HTML is processed for a report and not retained.
Security and tracking: The site states that it has no advertising trackers.
Support: Questions, corrections, and disagreements can be sent to maintainer Taylor Walsh at [email protected].
Rule currency: The site says its Google Search feature requirements were last verified on 2026-08-29 and that all 19 registry entries are marked provisional.
Limitations: The validator says it cannot determine whether Google will show a rich result, and the site says structured data does not guarantee one or improve ranking.
Audience: The site audit describes its grouped findings as a way to prioritize template-level fixes across a website’s pages.
Page validation: The validator checks structured data against Google’s documented Search feature requirements and whether marked-up values match visible page content.
