How to Track Product-Led Growth Events
5 min read·SaaS
What PLG events to track
Product-led growth is about self-serve conversion. The events that matter are:
- Activation events — first time a user does the thing that makes them "get it"
- Engagement milestones — 5th project, 10th event logged, first team member invited
- Friction moments — upgrade wall hit, feature locked, usage limit reached
- Intent signals — pricing page visit, plan comparison, billing page open
Activation event (the "aha moment")
ts
// Tracked when user logs their first event successfully
async function trackFirstEvent(userId: string, projectId: string) {
await logit.now("activation", {
event: "First event logged",
description: "User hit their aha moment",
icon: "🎯",
notify: true,
tags: { milestone: "activation" },
metadata: { userId, projectId, activatedAt: new Date().toISOString() },
});
}
Engagement milestones
ts
async function trackMilestone(userId: string, milestone: string, count: number) {
const milestones: Record<string, { icon: string; notify: boolean }> = {
"5_events": { icon: "⭐", notify: false },
"first_team_invite": { icon: "👥", notify: true },
"100_events": { icon: "🏆", notify: true },
"first_channel_created": { icon: "📢", notify: false },
};
const config = milestones[milestone];
if (!config) return;
await logit.now("milestones", {
event: `Milestone: ${milestone.replace(/_/g, " ")}`,
description: `User reached ${count} ${milestone}`,
icon: config.icon,
notify: config.notify,
metadata: { userId, milestone, count },
});
}
Upgrade intent signals
ts
// When user hits a usage limit or clicks "Upgrade"
async function trackUpgradeIntent(
userId: string,
trigger: "usage_limit" | "feature_gate" | "upgrade_button" | "pricing_page"
) {
await logit.now("upgrade-intent", {
event: "Upgrade intent signal",
description: `Triggered by: ${trigger}`,
icon: "⬆️",
notify: true,
tags: { trigger },
metadata: { userId, trigger, url: typeof window !== "undefined" ? window.location.href : "" },
});
}
What to do with this data
- Activation rate: % of signups who log their first event within 24h
- Time to activate: median time from signup to first event
- Upgrade intent rate: % of users who trigger an upgrade intent event
- Conversion from intent: % of intent → paid
Watch your activation and upgrade-intent channels daily. If activation drops, your onboarding broke. If intent spikes but conversions don't, your pricing page has a problem.
