The measurement layer that makes every other decision defensible. Without it, optimisation is guesswork with a dashboard on top — and the dashboard makes the guessing feel rigorous.
Browser restrictions, consent requirements and conversions that complete offline have quietly broken the default setup almost everywhere. The symptom is familiar: platform-reported conversions that do not reconcile with the CRM, and nobody able to say which number is wrong. That is not a reporting issue to be smoothed over — it is a data pipeline that needs rebuilding.
A pipeline that survives browser changes and closes the loop on offline revenue.
Because they measure different things at different moments, and each platform claims what it can see. The fix is a single source of truth in your own warehouse, with the platforms treated as inputs rather than as the record.
If a meaningful share of your traffic is on browsers that block third-party cookies, or your conversions complete offline, then yes. Otherwise you are optimising on a shrinking and biased sample.
Under European rules, tags must stay cookieless until a visitor consents. Configured properly with Consent Mode, you keep modelled conversions and lose far less signal than an incorrect setup would cost you.
