// Data & Analytics

Tracking you actually own. Live in 5 days.

We rebuild your GA4, server-side and conversion tracking so your numbers finally agree — then we hand you the keys. You own the stack.

73%of GA4 setups carry silent misconfig — SR Analytics

You think you have to choose: a big agency that sends decks and locks you in, or a freelancer who sets it up and disappears. Neither works when your numbers have to be right and yours to keep. That's why we built the Data Tracking Sprint — fixed price, five days, you own everything.

// How it works

Three steps. No black box.

01

Book a call

15 minutes. We look at your setup and tell you straight if a sprint will help.

02

We audit your setup

Access, consent, tags, server. We find what's silently dropping your data.

03

You get tracking you own

Rebuilt, validated, documented — in your own accounts. We hand over the keys.

// What's inside

No black box. Every part is a module.

Discovery & Access

We map every account and container — and make sure they're in your name.

CMP & Consent (v2)

Consent Mode v2 set up right, so you stay compliant without going blind.

Tagging Plan

One documented plan: every event, every parameter, named the same everywhere.

Client-Side Tracking

GA4 and GTM rebuilt cleanly — no duplicate tags, no guesswork.

Server-Side Tracking

sGTM + Conversions API so data flows from your server, not the browser.

Looker Studio Dashboard

The numbers that matter, in one view you can actually read.

QA & Validation

We test every event against reality before we hand it over. No surprises.

// The difference

×GA4 says X, Meta says Y — every meeting starts with an argument.
×Audiences dropped at Consent Mode v2.
×Tracking lives in an agency account you can't log into.

// What the agency told you

Let's clear a few things up.

"We need a 6-week discovery phase first."
We audit in 48 hours and rebuild in five days. You see progress daily.
"Tracking has to live in our managed account."
It lives in yours. We set up access, then step back. No ransom.
"You'll need us on retainer to keep it running."
Optional. The sprint is yours to keep — retainer only if you want upkeep.
// FAQ

The questions you're about to ask.

Do I really get this live in 5 days?+

Yes — once access is sorted on day one. The five days are working days, and you'll see each module land as we go.

What do you need from me to start?+

Admin access to your GA4, GTM and ad accounts, plus 30 minutes on day one. We handle the rest.

Will this break my current tracking?+

No. We build alongside what you have, validate it against reality, then switch over once it's proven.

Is this consent-compliant for the EU?+

Yes. Consent Mode v2 and a proper CMP are part of the sprint — compliant by default, not bolted on.

Who owns the accounts and data?+

You do. Everything is built in your own accounts and containers. We never hold your stack hostage.

What if my setup is a complete mess?+

That's the normal starting point. The Quick Scan tells us how deep it goes; most messes still fit in one sprint.

Do you work with Shopify / WooCommerce / custom?+

All three, plus headless setups. Server-side tracking works regardless of the platform underneath.

What happens after the sprint?+

You own it outright. Add the Data Engine retainer only if you want us keeping it healthy as you ship.

MejorSet stopped guessing.

Their GA4 and Meta numbers were off by a third and no one trusted the dashboard. We rebuilt tracking server-side in one sprint — and handed back every account.
