Data & Analytics
& Full-Stack.
Our Process
Tracking Audit and Measurement Plan
We audit your current GA4, tag, and event setup, then map every metric back to a business question in a documented measurement plan and event schema.
Instrumentation and Data Pipelines
We implement clean event tracking through GTM or server-side tagging and pipe raw data into a warehouse like BigQuery so nothing is sampled or lost.
Dashboards and Funnel Reporting
We build self-serve dashboards in Looker Studio or Power BI that expose acquisition, funnel conversion, and retention without anyone exporting a spreadsheet.
Experimentation and Optimization
We design and run statistically valid A/B tests against your biggest drop-off points, then translate the winners into prioritized next actions.
Stop guessing. Know exactly what is working and what to fix next.
We replace gut-feel reporting and broken tags with a measurement system you can trust, from the first event fired to the boardroom dashboard.
Our Benefits
We tie every event and dashboard tile back to a revenue or retention question, so reporting drives decisions instead of decorating slides.
We build tracking that survives ad blockers, iOS restrictions, and consent rules using server-side tagging and a warehouse you own.
We run experiments with proper sample sizes and significance, so you ship changes that actually lift conversion rather than chasing noise.
From raw events to confident decisions
Most teams do not have a data problem, they have a trust problem. Numbers disagree between GA4 and the ad platforms, events double-fire or stop firing after a release, and nobody is quite sure whether last month's lift was real or seasonal. erikservice fixes the foundation first: a documented event schema, clean instrumentation through Google Tag Manager or server-side tagging, and consent handling that keeps you compliant with GDPR and tracking restrictions. Once the collection layer is reliable, everything downstream, from attribution to forecasting, finally agrees with itself.
On top of that foundation we build the parts you actually use day to day. Dashboards in Looker Studio or Power BI surface your full funnel, from first touch to activation to repeat purchase, so you can see where users drop off and what it costs you. Conversion and funnel analysis pinpoints the highest-leverage friction points, and our experimentation program turns those into A/B tests with pre-calculated sample sizes and honest significance thresholds. The result is a continuous loop: measure, find the leak, test the fix, and bank the lift, with the raw data warehoused in BigQuery so you are never locked out of your own history.
Our Approach
We treat analytics as an engineering discipline, not a one-off setup. Clean data in, trustworthy decisions out, with you owning every layer.
-
Question before metric
We define the business decision first, then instrument only the events and reports that answer it, so dashboards stay focused instead of bloated.
-
Own your data layer
We pipe raw, unsampled events into a warehouse you control, so your analytics outlive any single tool or platform policy change.
-
Decisions, not dashboards
Every report ends in a recommendation and a prioritized test, so insight turns into shipped changes rather than another tab nobody opens.
Your questions, answered.
A focused GA4 and GTM setup with a core funnel dashboard typically takes two to three weeks, including the audit and a documented measurement plan. Server-side tagging and a BigQuery pipeline add roughly one to two more weeks depending on the number of events and platforms involved.
Usually yes, because most existing setups are installed but not instrumented. We commonly find missing conversion events, double-counted pageviews, no funnel definition, and no warehouse export. We audit what you have, fix the gaps, and document the event schema so future tracking stays consistent as your product changes.
We implement consent mode and respect your cookie banner choices, and we use server-side tagging to keep data collection accurate under ad blockers and browser restrictions while staying GDPR-aligned. We collect only the events tied to a defined business question, which keeps your data footprint lean and defensible.
It depends on your baseline conversion rate and the size of the effect you want to detect, but as a rule of thumb you want a few thousand conversions per month across the funnel area you are testing. For lower-traffic pages we prioritize bigger structural changes, longer test windows, or qualitative analysis instead of chasing small percentage tweaks.
You own everything: the GA4 and tag configuration, the warehouse and its raw data, every dashboard, and the documented measurement plan and event schema. We hand over with a walkthrough and written documentation so your team can self-serve reporting, and you can keep us on retainer for experimentation and new tracking as the product evolves.
