The definition

One visit to your site — pages viewed, actions taken — ending after ~30 minutes of inactivity. GA4's basic unit of traffic.

Why it matters to an owner

Sessions measure activity, conversions measure business. Rising sessions with flat conversions means the wrong visitors or the wrong page — dig, don't celebrate.

This is the work. Want it done?

Everything here is free to use yourself — that’s the point. If you’d rather a senior marketer just handle it, in your accounts and your name: 20-minute call, no pitch deck.
