Tag Manager
Google Tag Manager is the most powerful and most misused tool in the analytics stack. A misconfigured GTM container corrupts everything downstream.
What’s included
Block 02 — The Problem
Most GTM containers were set up once and never properly audited again.
Tags added by different team members over different periods. Triggers that fire on conditions nobody remembers setting. Duplicate GA4 tags from a migration that was half-completed. These are the standard findings in a GTM audit of a container in use for more than two years without structured oversight.
Block 03 — Our Approach
Audit. Restructure. Implement. Document.
Container audit: Full review of every tag, trigger, and variable — identifying misfires, duplicates, conflicts, and deprecated configurations
Data layer architecture: Design or restructure the data layer to support the events your business needs to track cleanly and reliably
Custom event tracking: Configure advanced event tracking — form interactions, scroll depth, video engagement, ecommerce events
Consent mode implementation: Correct consent mode v2 configuration ensuring compliant tracking across all regions
Server-side tagging: Where applicable, migrate to server-side GTM for improved data accuracy and enhanced first-party data collection

Block 05 — Cost of Delay
A misconfigured GTM container is corrupting your data right now. Every report built on it is unreliable.
GTM errors do not self-resolve. A duplicate GA4 tag fires twice on every pageview until it is removed. These are not problems that get better with time — they accumulate data debt that makes historical analysis increasingly unreliable.
A broken container corrupts every report downstream. A conversation costs nothing.
One container audit identifies every issue. Every data point collected after it is data you can trust.
