Product-Qualified Leads (PQLs)
Users whose product engagement signals conversion likelihood. Quality over quantity.
PQLs = Count of users meeting predefined engagement criteria
PQL Rate = (PQLs / Total trial or free users) × 100%
What it measures
Users who have demonstrated meaningful product engagement that correlates with conversion likelihood. Unlike marketing-qualified leads (based on content engagement), PQLs are qualified by actual product usage.
What to watch
- Rising: More users are reaching meaningful engagement, which is good for pipeline. Track PQL-to-paid conversion to validate your criteria.
- Falling: Fewer users are engaging deeply. Check if onboarding is broken, if traffic quality has declined, or if product changes have made the "aha moment" harder to reach.
In practice
A SaaS company defined PQLs as "created 3+ projects and invited 1+ teammates." Sales closed 35% of PQLs vs. 8% of all trial users. When they added "used integration feature" to the criteria, PQL volume dropped 40% but close rate jumped to 52%. Better targeting made their sales team more efficient.
