See every featureFeedKill Watch helps Shopify merchants running Google Shopping and product feeds catch eligibility issues before ad spend flatlines. The app polls your catalog daily via Admin GraphQL for missing GTINs, unpublished products, and title policy flags, then merges pasted Google Merchant Center disapproval exports into one prioritized alert feed inside Shopify admin.
Preflight Product Feed Checker scans your Shopify catalog for product data issues before they affect product feeds, Google Shopping, or ads. It flags missing GTINs or barcodes, missing images, invalid prices, out-of-stock active products, draft products, and other feed risks. Use the review queue to open affected products, fix issues in Shopify, or ignore intentional warnings.
