Third-party scripts on ecommerce storefronts

Per-domain statistics for the third-party scripts seen during scans of live stores: how often each host appears, its typical size, and integrity coverage.

Published hosts

No host has reached the publication threshold

A host is published once it has been observed on enough distinct stores for the figure to mean anything.

How these figures are produced

Every share is reported against the number of stores it was measured on, split by the store software, and dated to the run that produced it. Two populations that behave differently are never pooled into one number.

Aggregates only. No individual store is named, a host is published only once it has been seen on enough distinct stores, and no measurement identifier is ever published.
