Measure what percentage of signups reach your "aha moment."
Activation rate
—
Activation rate is the percentage of new signups who reach a meaningful milestone in your product — the moment they experience real value. Common activation events include creating a first project, sending a first message, or completing setup. High activation rates predict strong retention.
Define "activated" as the specific milestone where a user has experienced your core value. Track this for cohorts (e.g., users who signed up in March) rather than rolling totals to spot trends.

Produktly gives you tours, checklists, NPS, surveys, feedback widgets, roadmaps, and changelogs in one tool. Starting at $19/mo.
It depends on your product. For Slack, it was sending 2,000 messages within a team. For Dropbox, it was uploading one file to one device. Pick the action that correlates most strongly with users sticking around long-term.
Reduce signup friction, guide new users to the activation milestone with onboarding tours and checklists, send activation-focused emails in the first 7 days, and remove obstacles between signup and value.
Track each new signup cohort by week or month. Define a clear binary event ("user X did action Y within Z days") and calculate the percentage that completed it.
