Interpretations are based on observed StoreCensus data. Directional observations only - not financial or business advice.
Based on StoreCensus tracking of 2,226,599 active Shopify stores.
Data is refreshed on a weekly basis and reflects observed platform activity across active ecommerce stores. StoreCensus detects app and plugin installations through storefront signature analysis including JavaScript signatures, API calls, and HTML markers — measuring current active installations, not historical download counts.
StoreCensus continuously discovers and indexes active Shopify storefronts globally. Our crawler identifies 2,226,599+ live stores through domain analysis, platform signals, and third-party data sources.
App and plugin installations are detected through storefront signature analysis — including JavaScript bundle signatures, API endpoint patterns, HTML data attributes, and network request fingerprints. This identifies apps that are currently active, not merely historically downloaded.
Each store is re-scanned on a recurring basis. Historical snapshots are retained to calculate 30-day, 90-day, and year-over-year growth rates. This enables trend analysis that reflects actual merchant behavior over time, not just point-in-time counts.
Disclaimer: Estimated metrics (revenue, traffic) should be considered directional estimates rather than audited financial data. Active install counts reflect StoreCensus detection capability and may not capture 100% of installations for apps with non-standard implementation patterns.
This page presents data from the Shopify Product comparison App Statistics proprietary StoreCensus dataset. Statistics may change over time as stores are discovered, removed, or updated in our index.
StoreCensus does not receive compensation from app developers or vendors for rankings or placement. All rankings are determined solely by observed installation data across tracked Shopify storefronts.
