A data layer without documentation is a liability — developers don't know what to push, analysts don't know what's available, and every team change means knowledge loss. We create comprehensive data layer documentation covering: every event name and trigger condition, all data layer variables with type definitions and example values, platform mappings (which variables feed which tags), and implementation examples for your tech stack — delivered as a living document your team can maintain.

Test conversions, GA4 DebugView confirmation, and full documentation handed to your team.

Yes — we document the GTM container setup (tags, triggers, variables) in addition to the website-side data layer, so the full picture is clear.
