Using Tarsier

Events & goals

Pageviews tell you where people go. Events tell you what they did when they got there — signups, purchases, downloads, button clicks.

Track an event

From anywhere after initialization:

Tarsier.trackEvent({ name: "signup" });

// with extra context
Tarsier.trackEvent({ name: "purchase", data: "plan=pro" });

Names are free-form but permanent-ish: pick something you will still understand in a year, like signup_completed rather than btn-click-7.

Promote it to a goal

  1. Open the Events card on your dashboard.
  2. Find the event under “seen but not goals” and add it, or type the name into the goal box.
  3. Completions and conversion rates appear next to your traffic from then on.
Events are the difference between “12,000 people visited” and “214 people signed up.” Track the second thing.
