# Data Measured

> Data, measured properly. Measurement, attribution and first-party data — explained for operators, with one installable artifact per issue. Twice a week, every citation verified.

Editorial: The Editorial Team. A free twice-weekly briefing (Mon & Thu) on measurement, attribution and first-party data; sign up at https://datameasured.com/#/portal/signup.
Every issue: one artifact you can install (SQL, GTM configs, consent snippets, audit checklists), one dated and sourced benchmark, and the GDPR lens first — what a change means legally before what it means technically.
