Every schema markup on any page, detected, decoded, and validated. Schema Auditor lives in Chrome's side panel and shows you exactly what structured data a page carries and whether it qualifies for rich results, the moment the page loads. Stop copy-pasting URLs into online validators. Browse your site (or your competitor's), and the audit is already done. WHAT IT DETECTS • JSON-LD — including blocks injected late by Google Tag Manager and single-page apps that copy-paste testing misses • Microdata (itemscope / itemprop, with itemref support) • RDFa • A toolbar badge shows the schema count on every page, colored by health — green, amber, or red WHAT IT VALIDATES • JSON syntax errors with line numbers and plain-English hints ("looks like a trailing comma", "smart quotes aren't valid JSON") • Required properties for rich results — missing ones are flagged as errors that block eligibility • Recommended properties that limit how your result can appear • Value formats: ISO 8601 dates and durations, URLs, price and currency, availability, rating ranges • Typo'd schema.org types, missing @context, dangling @id references • Duplicate schemas — catch two SEO plugins both emitting Organization markup 25+ types covered: Product, Article, FAQPage, Recipe, Event, JobPosting, LocalBusiness, BreadcrumbList, VideoObject, Review, HowTo, Organization, Course, Dataset, SoftwareApplication, ClaimReview, and more. BUILT FOR REAL AUDITS • Per-schema verdict: see instantly whether each entity is eligible for its rich result type • Expandable property trees — read nested markup without squinting at raw JSON • Raw view with pretty-printed source and one-click copy • Export a standalone HTML report you can send to a client or developer • One click to re-test any page in Google's Rich Results Test for a second opinion • Dark and light themes WHO IT'S FOR SEO/AEO/PPC professionals auditing client sites. Developers debugging structured data. Agencies producing audit deliverables. Site owners who want to know why their stars, FAQs, or breadcrumbs stopped showing in search. PRIVACY Schema Auditor collects nothing. No analytics, no accounts, no network requests — every scan and validation happens locally in your browser, and results are discarded when you close the tab. From the maker of Pixel Auditor, the tracking pixel and consent-mode inspector. Schema Auditor is an independent tool and is not affiliated with or endorsed by Google. "Rich results" criteria are based on publicly documented search feature guidelines.
