peeq — Schema & JSON-LD Validator for SEO & GEO

A quick peek into any page's structured data — schema and JSON-LD, instantly.

Structured data, checked — not just shown. peeq reads the schema.org markup on the page you're looking at, JSON-LD (including @graph, arrays and deep nesting) and Microdata, and then tells you what's wrong with it: required fields that are missing, malformed dates, relative URLs where absolute ones are needed, @id references that point at nothing, and what a Product, Article, Recipe or Event still needs to qualify for a rich result. Now the page itself gets a grade. The Overview reads the whole page and scores 12 essentials: title, meta description, canonical, indexability, headings, Open Graph, structured data, image alt text, HTTPS, language, favicon and viewport, each weighted by how much it matters. Every check opens into the measured fact behind it: the actual title and its length, the full heading structure, the images missing alt text. Structured data is how search engines and AI answer engines read your pages. The foundation of technical SEO and of GEO (Generative Engine Optimization). peeq checks that foundation against Google's documented requirements, right in your browser. WHY PEEQ • Honest: when peeq has no rules for a type, it says "not checked" instead of showing a green tick it hasn't earned • Private: zero network requests. Your markup never leaves the browser — validation runs against rules bundled inside the extension, not somebody's API • Readable: built for humans first; the raw JSON is always one toggle away WHAT IT DOES • An Overview that grades 12 on-page essentials, with the measured fact, never advice, behind every check, and a "?" that explains why each one matters; • Validation with four honest states: valid, warning, error, and not checked; • Rich-result gaps, spelled out field by field; • A side panel you can leave open. Site sessions keep a running count of the pages you've checked, how many are valid, warn, or are broken. One click per page; • Compact grid: identical schemas collapse into one ×N row, so the list never forces a scroll; • Readable property sheets plus a full code viewer with copy; • Export a session as JSON, or open a printable report and save it as a PDF; • Optional local history: encrypted, summaries only, never leaves your device, and never records private or incognito pages; • Dark and light themes, in English, Portuguese (BR), Spanish, German, Japanese and French. ABOUT PERMISSIONS peeq works on the page you ask it to check (toolbar click or right-click menu) and nothing more. Nothing runs before that click and there are no other optional permissions to grant. peeq declares access to one Google API origin ahead of a planned performance check; we make zero network requests. Everything runs in your browser. peeq is an independent project. Not affiliated with Google or schema.org.
