What is a product qualified lead?

Unlike an MQL, which rests on fit and engagement, a PQL is grounded in what the person did inside the product. That behaviour is a much harder signal than opening emails or downloading a guide.

Typical PQL signals include reaching a usage limit on a free or freemium tier, inviting teammates, or repeatedly using a core feature. These actions show real value has been experienced, not just interest.

PQLs only exist if you have a product you can instrument to capture that behaviour. Where you can, they are usually the highest quality signal available, because they measure demonstrated value rather than demographics.
