Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCatalogGuard helps merchants review product catalogue completeness from within Shopify Admin. It scans product information using read-only access, identifies common issues, and organises findings by severity and type. Merchants can open affected products in Shopify, make corrections, and run another scan to verify changes and refresh their catalogue health score. CatalogGuard does not modify product data.
Many product listings have weak titles, short descriptions, or missing SEO fields that are hard to spot across a large catalog. Product Content Optimizer scores each product on title, description, SEO, completeness, and clarity, then shows clear issues and recommendations in Shopify Admin. On Growth and Pro plans, review rule-based rewrite suggestions for titles, descriptions, and SEO.
