Why is GA4 alone not enough for B2B attribution?
GA4 measures sessions and site events, while the B2B commercial opportunity is recorded in CRM weeks or months later, often by a different person than the visitor. Without a key connecting both sides, GA4 attributes results to the last digital contact.
In a long cycle, that point is often branded search by someone who had already decided — leading budget to the channel that captures demand rather than generated it.
