Stuck at any point? Ask an AI about this page →Analytics answers what happened; CRO decides what to change. They are separate skills and this section covers both, because a measurement setup nobody acts on and a test programme with untrustworthy data fail the same way.
Start with the fundamentals and the GA4 setup if the numbers are not yet trusted — everything downstream depends on that. If the data is sound, go to experimentation.
A theme runs through the section: a metric with no decision attached is a number you will report for two years and never act on.
