Comprehensive Google Analytics & GTM Setup

I need a complete health-check and configuration of my Google Analytics account, with all tracking routed cleanly through Google Tag Manager. The goal is rock-solid data accuracy from the very first session.

Please audit the current Analytics property, confirm the settings match best practices, and build (or repair) the GTM container so that every tag is organised and easy to maintain. From there, set up and deploy the required tags, configure detailed event tracking for the key actions I will specify, and troubleshoot any issues you uncover during testing.

Deliverables
• Fully-configured GA property (accounts, data streams, filters, enhanced measurement)
• Clean GTM container with version control and naming conventions
• Event tracking implemented and verified in Debug mode and real-time reports
• Written or video hand-off explaining how to add or edit tags

All events must fire correctly in GTM Preview, appear in GA real-time and standard reports with the agreed naming, and introduce no console errors. Once those checks pass, the job is done.
