Built for SEOs, e-commerce developers, and Shopify/WooCommerce/Magento store owners who need to verify structured data without digging through Google's documentation every time. WHAT IT CHECKS • Product Snippet requirements — name, image, offers, review/aggregateRating • Merchant Center Listing fields — price, priceCurrency, availability, itemCondition, GTIN, MPN, SKU, brand • Google's 2026 category property — Text, CategoryCode (Google Product Category), and array formats • Sale Duration — validFrom, validThrough, priceValidUntil, and StrikethroughPrice sale pricing • Shipping details — shippingRate, shippingDestination, delivery time • Return policy — MerchantReturnPolicy, return windows, return fees • Product variants — ProductGroup, variesBy, hasVariant, inProductGroupWithID • Apparel attributes — size, sizeSystem, sizeGroup, gender, ageGroup, pattern • Dimensions — weight, depth, width, height with proper QuantitativeValue units • BreadcrumbList structured data — itemListElement, position sequencing, required properties • Connected Graph / Structured Data Triangle — verifies @id references between Product, Offer, Brand, and Organization nodes actually resolve, so your schema isn't a disconnected island HOW IT WORKS 1. Open any product page 2. Click the extension icon (or open the side panel to keep it visible while you browse) 3. Get an instant pass/fail breakdown grouped by Required vs Recommended, with plain-language explanations for every check 4. Copy a summary of missing fields to share with your developer 5. Jump straight to Google's Rich Results Test or the Schema.org Validator with one click WHY IT MATTERS Structured data errors are one of the most common reasons products don't qualify for Free Google Shopping Listings, star ratings, price snippets, or availability badges in search results. This tool catches the gaps — including ones that look "technically valid" but are actually incomplete — before Google's own testing tools flag them. SIDE PANEL SUPPORT Keep the audit panel docked alongside your browser tab. It automatically re-scans as you navigate between product pages, so you can audit an entire catalog without reopening a popup every time. PRIVACY This extension reads only the structured data already present on the page you're actively viewing. Nothing is collected, stored, or sent to any server — all auditing happens locally in your browser. Built by Faiz Azizan — drfaizazizan.com ```
