Server-side tracking, GA4 and Consent Mode v2 for brands scaling ads
Defined Chase sets up server-side tracking, GA4, Consent Mode v2, Meta Conversions API, Google enhanced conversions and offline conversions for brands spending $100,000+ a month on ads. The goal is simple: numbers you can trust before you raise the budget, so bidding learns from real revenue and your team stops arguing about which report is right.

4.9★★★★★across 30+ client reviewsWho it is for
We are a fit for a small number of teams, and we say so on the first call.
Good fit
- Brands spending $100K+ a month, or planning to
- Teams where ad platforms, GA4 and the backend disagree
- Companies in the EU and UK that need Consent Mode v2 done properly
- Apps, e-commerce, SaaS and B2B with CRM or backend data
Not a fit
- Sites with no conversion worth tracking yet
- Teams that want a cookie banner only, not working tracking
- Anyone who will not give access to GTM, the site and the CRM
What we do
Six things decide whether more budget makes more profit.
Find the gaps
Cookie banner, GTM container, dataLayer and every key conversion checked against the backend.
Consent Mode v2
A consent platform wired to Google and other tags, so nothing fires before consent and modelled data still works.
Server-side container
Events cleaned, deduplicated and enriched with first-party data before they reach the platforms.
Conversions APIs
Meta Conversions API, Google enhanced conversions and TikTok Events API.
Real outcomes
Qualified leads, paid orders and renewals from the CRM or backend sent back for bidding.
Tested and documented
Every consent scenario tested, a short write-up of what was done, and support after go-live.

FAQ
What is server-side tracking?
Instead of every tag sending data from the browser, events go to your own server container first. It cleans and enriches them, then sends them to Google, Meta and others. You lose less signal to ad blockers and browsers, and you control what is shared.
Do I need Consent Mode v2?
If you advertise to people in the EEA or UK with Google, yes. Without it you lose access to features and conversion modelling, and you risk tags firing before consent.
Why do GA4 and my ad platforms never match?
They count differently: attribution models, windows, consent and deduplication all differ. We reconcile them against your backend so you know which number to run the business on.
How long does it take?
A typical setup for one domain is planned in steps: access and audit, implementation, testing across consent scenarios, then go-live and support.
Can this be a standalone project?
Yes. Tracking can be fixed as part of an X-Ray or as its own project before any media management.
