Product Qualified Lead PQL
A Product Qualified Lead (PQL) is a free trial or freemium user who has reached a predefined product usage milestone that indicates strong purchase intent and likelihood to convert to a paying customer. PQLs are identified through in-product behavioral signals rather than traditional marketing engagement. The PQL model is the foundation of product-led growth (PLG) go-to-market strategy.
PQL criteria should be derived from cohort analysis comparing the product behaviors of users who converted to paid vs. those who did not, identifying the specific aha-moment actions that most predict conversion.
