Compare visible product details, structured data, and one local feed row on the current product page. Merchant Match Preflight is a local preflight checker for Shopify and WooCommerce product pages. Use it when investigating a Google Merchant Center price or availability mismatch, or before resubmitting product data after a store change. On the page you open, it compares visible product details with Product or ProductGroup structured data and, optionally, one local CSV, TSV, or JSON feed row. Review the evidence and suggested repair, make the correction, then rescan to see whether the supported finding was resolved. Main features: * Compare visible price, sale price, currency, and availability with Product or ProductGroup offers in JSON-LD or basic microdata. * Check supported title, brand, SKU, GTIN, MPN, and selected-variant conditions. * Optionally compare one local feed row with visible and structured values. * Review severity, evidence sources, and a suggested repair for each finding. * Export the current report and compact local scan evidence. * Keep up to 50 local history records for 30 days and clear them at any time. No account is required. Product-page and feed content is processed locally. Optional pseudonymous usage measurement is off by default and requires separate consent. It does not receive page URLs, domains, product or feed contents, prices, customer identities, or browsing history. Scope and limits: * Supports Shopify and WooCommerce product detail pages. * Does not sign in to Google Merchant Center or inspect account diagnostics. * Does not validate sale_price_effective_date, crawl a catalog, modify pages or feeds, or upload product data. * Results are a preflight aid, not a guarantee of Merchant Center approval or policy compliance. Merchant Match Preflight is an independent product and is not affiliated with Google.
