How it's built
Built from daily snapshots of public Chrome Web Store listings. User counts are the active-user figures the store displays. Recoveries, short-lived spikes and installs pushed by large companies or schools are left out. The store rounds larger counts, so multiples above 1,000 users are measured conservatively.
