Tracking
& Data
We build the measurement your decisions deserve: a clean event plan, server-side collection, consent handled properly, GA4 and the ad platforms fed the same truth, and a warehouse where spend, revenue and margin finally sit in one table.
Three ways measurement drifts, and what each one costs you.
Four dashboards, four answers, one budget
Meta, Google, GA4 and the store each report a different number for the same week, and each is right on its own terms. Meetings turn into attribution debates. The budget goes to whoever argued best, which is a strange way to spend a million euros.
The pixel is losing signal, quietly
Browser restrictions, consent refusals and ad blockers strip a large share of events before they reach the platforms. The algorithms optimize on what is left, which is not a random sample of your customers. Performance decays, the platform blames the creative, and nobody looks at the plumbing.
Consent was implemented as a banner, not as a system
A banner appeared, a box was ticked, and the tags kept firing regardless. That is a regulatory exposure and a data problem at once: the numbers are contaminated and you cannot prove otherwise. Compliance done properly is also, conveniently, better measurement.
Certified on the tools we measure with.
How we run it, and why it holds.
“Prescient provided us with the right methodology and technical foundations to scale.”
A measurement plan before a single tag
Which decisions the data must support, which events and parameters prove them, what a conversion is worth, and who owns each definition. Written down, agreed, and used as the spec for everything that follows. Most tracking problems are naming problems that got expensive.
Server-side collection, done properly
A first-party endpoint, server containers for GA4, Meta, Google and the rest, deduplicated against the browser, with enriched conversion values and match keys so the platforms recognize more of your customers. Event match quality goes up. So does everything downstream of it.
Consent that holds up, and data that survives it
A consent platform configured to your legal reality, Consent Mode and its equivalents wired correctly, modelling where it is allowed, and a clean record of what fired and why. Your DPO sleeps. Your analyst gets usable numbers. Both are rarer than they should be.
One table where spend meets margin
Ad platform costs, store or CRM revenue, returns and margin loaded into a warehouse on a schedule, joined on keys we chose, and served through a reporting layer you own. The dashboards stop disagreeing because they read the same rows. Then the interesting conversations can start.
Proof, in their numbers.

Frequently Asked Questions
Measurement planning, tag management, server-side collection, consent, analytics configuration and a warehouse with reporting on top, built by the people who also spend the media and therefore care whether the numbers are true.
If you spend on paid media and rely on the platforms to optimize, yes, and sooner than most think. The signal you feed the algorithm is the ceiling of its performance. Below a few thousand euros a month the answer may be a well-configured browser setup first, and we will say so.
It will make attribution honest, which is different from making it flattering. Cleaner data, consistent definitions and a joined view of spend and revenue remove most of the arguing. The remaining questions get answered with incrementality tests, not with another dashboard.
GA4, Google Tag Manager and its server container, Meta Conversions API, the ad platforms’ APIs, Didomi and the main consent platforms, BigQuery, Snowflake and PostHog, plus your store or CRM. We prefer the boring, well-documented stack. It is the one still running in three years.
Below roughly €5k a month in media we are usually not the right partner yet, and we will say so on the first call. Above it, the first conversation is free. The Diagnostic that follows is paid, and its fee is deducted if we go on to work together.
See whether your numbers would survive an audit.
It starts with a conversation, on us. If there is a fit, the Diagnostic that follows is paid, thorough, and yours to keep. If there is no fit, you will have spent thirty minutes and gained an honest opinion, which is still a decent trade.
