Why we picked it Once you have decided that signups and leads are what count, GA4 is the free tool that connects a content visit to that action. This is Google's own reference on key events, the setting that lets you flag "newsletter signup" or "demo requested" as the outcome you measure, so a blog post's worth is tracked by conversions, not sessions. It pairs naturally with Search Console: one shows how people find you, the other shows what they do next.
About key events (conversions) in Google Analytics 4 (official docs)
From Google Analytics Help by Google Analytics team
- A key event is just an existing event you mark as important, so you tag actions like signup, lead, or purchase and then measure content against those, not against traffic.
- GA4 is free and lets you mark up to 30 key events per property, which is plenty to cover the handful of outcomes a founder actually cares about.
- If you prefer a lighter, privacy-friendly setup, Plausible tracks custom goals the same way, the principle is identical: define the conversion first, then read content by it.
