Most stores have hundreds of products missing images, descriptions, or tags — silently hurting conversions and SEO. CatalogCheck scans your entire catalog and flags every gap: missing or thin images, weak descriptions, short titles, missing tags, product types, categories, and duplicate SKUs. Export the full list as a CSV in one click. No setup, no editing, no risk — CatalogCheck is read-only and never changes your products. Works for every Shopify store.
