Marketing Qualified Lead (MQL)
A Marketing Qualified Lead (MQL) is a lead that has demonstrated a level of engagement or intent that suggests readiness for sales follow-up, based on criteria defined jointly by marketing and sales teams. MQL criteria typically include engagement thresholds such as content downloads, webinar attendance, or website behavior combined with ICP fit indicators such as company size and industry. The definition of an MQL should be regularly reviewed and calibrated against conversion data to ensure marketing is delivering leads that sales can actually close.
Why It Matters
The MQL definition is the primary interface between marketing and sales — and it is frequently the source of the most damaging internal conflict in B2B organizations. An MQL definition that is too loose sends unqualified leads to sales; too restrictive, and sales lacks enough pipeline. Calibration against conversion data is the only way to know if the definition is working.
Example
A SaaS company revises its MQL criteria after discovering that leads from their webinar series convert to closed deals at 4x the rate of ebook downloads. They shift MQL weighting to weight webinar attendance more heavily — improving MQL-to-SQL conversion by 30% within one quarter.
