Google Analytics is Google’s web and app analytics platform used to measure traffic, events, audiences, engagement, and outcomes.
It matters because analytics turns marketing activity into decisions. Without clear measurement language, teams may misread performance, overvalue the wrong channels, or miss the actions that actually drive revenue.
Example
A business uses Google Analytics to compare visits to a service page with completed inquiry events. It first verifies the events and traffic filters, because a polished report cannot compensate for duplicate events or missing measurement.
