What is a Product Qualified Lead?
A Product Qualified Lead (PQL) is a user who has demonstrated buying intent through product usage. Unlike Marketing Qualified Leads (MQLs) based on content engagement, PQLs show intent by using the product in ways that predict conversion.
Common PQL criteria include: reaching usage limits, inviting team members, using premium features in trial, or completing key activation milestones.
Why PQLs Matter
PQLs convert at much higher rates than MQLs because they've experienced product value firsthand. Sales teams focusing on PQLs rather than cold leads close more deals with less effort.
PQL models work especially well for product-led growth companies where users can self-serve before talking to sales.
Building a PQL Model
Analyze what actions predict conversion. Look at usage patterns of converted customers vs churned free users. Common signals: feature depth, frequency, team size, integration setup. Score users and trigger sales outreach when they hit PQL threshold.
Formula
PQL Rate = Users Meeting PQL Criteria ÷ Total Users × 100
Define PQL criteria based on actions that predict conversion
Example
Freemium conversion funnel:
- Free signups this month: 1,000
- Users hitting PQL criteria: 150
- PQLs converted to paid: 45
PQL Rate = 150 ÷ 1,000 = 15%
PQL Conversion = 45 ÷ 150 = 30%
15% of free users show buying signals. Sales should focus on these 150, not all 1,000.
