Method and limits
StoreRadar.co checks public Shopify storefronts and counts the signals it can see. We checked this group on 22 September 2026. Counts can change as stores and their tools change.
A signal is a clue from a public storefront. It is not proof of a subscription, performance, revenue or buying intent.
