Product-Qualified Leads (PQLs)
Users whose product engagement signals conversion likelihood. Quality over quantity.
What it measures
Users who have demonstrated meaningful product engagement that correlates with conversion likelihood. Unlike marketing-qualified leads, PQLs are qualified by actual product usage.
Calculation Variants
- PQL (Product Qualified Lead)
- Measures individual user engagement. Used mostly in bottom-up PLG motions (e.g., a single user hits a paywall).
- PQA (Product Qualified Account)
- Aggregates usage across all users in a tenant. Used in B2B enterprise motions (e.g., 3+ users from the same domain active in a week).
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.
Illustrative scenario — a representative composite, not a specific company.
