Collection tools stop at the raw export. We turn that analytics data into tested transformations and activation-ready outputs with clear lineage and ownership.

Start with the smallest task that covers the decision at hand. It should also match the system boundary and the evidence you'll need for acceptance.

Data Enrichment & Transformation

The versioned enrichment and transformation model joins and normalizes analytics data, adds derived fields, removes duplicates, and keeps tests, lineage, and activation-ready outputs with the work.

The exports have already landed and stay untouched; this is where inconsistent campaign and channel labels become joined tables a dashboard or model can actually read.

Transform, enrich, test, and activate analytics data beyond collection tools with explicit lineage and ownership.

GA4 owns exports and collection tools. Engineering owns durable transformations and downstream models.

Every engagement has named inputs, owners, human approval gates, reproducible QA, explicit limitations, and an operating handover.

We transform raw analytics streams into structured, version-controlled data models ready for business analysis. Zeo specialists author dbt models, automated data quality tests, and BigQuery schemas, while your data team owns business logic definitions and warehouse access.

A rigorous data pipeline development process from raw logs to warehouse data models.

Model raw analytics data
We clean, parse, and structure raw GA4 BigQuery export tables into normalized relational or dimensional data models.
Build transformation pipelines
We write modular, version-controlled dbt models and SQL scripts for recurring sessionization, attribution, and user metrics.
Implement data testing
We configure automated data quality assertions checking for primary key uniqueness, non-null constraints, and metric anomaly thresholds.
Activate downstream
We connect modeled warehouse tables to BI tools, reverse-ETL integrations, and marketing automation platforms.

A client describing the planning and reporting problems we started from.

Before working with Zeo, we had serious problems, especially with planning and measurement. Because we couldn't get complete measurements and reports, we struggled to evaluate our work. Evaluating the data correctly, in line with scientific rules, was the most important thing for us.
